* Zygote stage (0-2 weeks) * Embryonic stage (3-8 weeks) * Fetus (9-38 weeks) ## Footnote Each stage has distinct characteristics and developmental milestones.
31
What happens on Day 0 of the zygote stage?
Ovum and sperm fuse to form a zygote ## Footnote This marks the beginning of prenatal development.
32
What occurs on Day 6 of the zygote stage?
Zygote is down the fallopian tube and cells divide to form a sphere ## Footnote This is part of the early development process.
33
When does the embryonic stage begin?
At the end of implantation ## Footnote This stage lasts until the 8th week of development.
34
What is a key characteristic of the embryonic stage?
Period of intense vulnerability ## Footnote The embryo is highly vulnerable to outside influences such as disease and drugs.
35
What significant development occurs by Week 3 of the embryonic stage?
Neural tube begins to form ## Footnote This is crucial for brain development.
36
What happens to the heart by the end of Week 4 in the embryonic stage?
Heart becomes visible ## Footnote Blood vessels and lungs begin to develop during this week.
37
What major milestones are reached by Week 8 of the embryonic stage?
* All major organs present (except sex organs) * Basic structures of brain and central nervous system established * Very light (around 40g) ## Footnote This marks the end of the embryonic stage.
38
What is the duration of the fetal period?
Lasts 32 weeks ## Footnote This stage is focused on the continued development of organs.
39
At what gestational age does viability start?
Around 23-24 weeks ## Footnote This is when the fetus can potentially survive outside the womb.
40
What fetal behaviors develop around 6 weeks?
* Moving limbs * Head movements * Swallowing * Breathing * Hiccupping ## Footnote These behaviors indicate the fetus is developing motor skills.
41
Define teratogens.
Foreign agents that can cause abnormalities in the fetus and embryo ## Footnote Teratogens can include drugs, diseases, and environmental factors.
42
What are examples of illegal teratogens?
* Heroin * Cocaine * LSD * Methamphetamines ## Footnote These substances can have harmful effects on fetal development.
43
What effect does cocaine have on fetal development?
* Growth restriction * Irritability * Withdrawal symptoms * Lower birth weight * Increase in hyperactivity disorders ## Footnote Cocaine reduces blood flow to the placenta.
44
What are the effects of heroin on fetal development?
* Lower birth weight * Shrunken head circumference * Cognitive impairments ## Footnote Heroin passes into the fetus's bloodstream.

48
At what gestational age do ears develop?
Around Week 8 post-conception ## Footnote This is when the fetus begins to have the ability to hear.
49
What can fetuses hear by Week 16?
Fetus perceives sound outside the womb through fluid-filled ears ## Footnote They begin to learn vocal rhythms and patterns.
50
What study did DeCasper & Spence (1986) conduct related to fetal hearing?
Mothers read Dr. Seuss books out loud while pregnant ## Footnote Newborns preferred listening to these books after birth.
51
Can reading to a fetus stimulate brain development?
Currently, no evidence supports this ## Footnote The amniotic fluid filters sound, limiting what the fetus can hear.
52
What do infants prefer in terms of voice recognition?
Infants prefer playback of mother’s voice to voices of other women ## Footnote This indicates early recognition and preference for maternal sounds.
53
What can fetuses taste by Week 16?
Fetuses can experience taste through amniotic fluid ## Footnote Tastes pass into the amniotic fluid from the mother.
54
What were the findings of the Mennella, Jagnow & Beauchamp (2001) study?
Infants exposed to carrot juice preferred carrot-flavored cereal ## Footnote This indicates that fetal taste exposure influences food preferences.
55
What innate abilities do infants have regarding taste?
* Detect sweet, savoury, bitterness, sourness, and umami * Salt develops after 4 months ## Footnote Infants react negatively to sour tastes.
56
How do infants react to their mother's voice?
Infants experience slower heart rate when hearing mother’s voice ## Footnote This indicates a calming effect.
57
At what gestational age do eyes begin to develop?
Week 7 ## Footnote This marks the beginning of visual development.
58
What is the visual acuity of newborns?
20/200 ## Footnote Normal adult vision is 20/20.
59
What are the key points about prenatal physical development?
* Includes zygote, embryonic, and fetal stages * The embryo is particularly vulnerable to outside influences * Teratogens can cause abnormalities * Fetuses and neonates have sensory abilities ## Footnote This summarizes the main aspects of prenatal development.
60
What is emotion?
Emotion: a psychological state characterized by subjective feelings, physiological arousal, expressive behaviours, and cognitive appraisal, influencing how individuals perceive and respond to their environment
61

Develops very early – within first 2 weeks. One of the earliest emotions to develop
62
What is the possible adaptive function of distress?
 Indicates to others the infant has basic needs that are unmet
63
When does sadness and anger develop?
- Around 2-3 months – anger and sadness expression start to differentiate - Around 3 months – infant’s cries can be categorised
64
How do differentiations between expressions occur?
- Differentiations between expressions believed to be learned - Based on feedback from environment in meeting the infant’s needs
65
When does wariness and fear develop?
- Around 4 months – infants show wariness  Stranger wariness: distress in presence of unfamiliar adult  Involves signs of caution, hesitation, or distress in response to unfamiliar people or situations
66
What are the possible adaptive functions of wariness?
 May serve as a protective mechanism to prevent harm or danger by prompting infants to approach unfamiliar stimuli with caution
67
What was the 'Little Albert' experiment ?
An experiment to study fear in infants
68
What was the method of the 'Little Albert'?
Little Albert played with a white rat = not afraid A hammer makes a loud noise = afraid A hammer makes a loud noise while Little Albert is playing with white rate = afraid The whit rate alone (no noise)  afraid
69
What was the outcome of 'Little Albert'?
- Infants can learn fear - Fear can be generalised in infants
70
What are some criticisms of the 'Little Albert' experiement?

ability to monitor, evaluate, and modulate one’s emotional responses
80
When does emotional regulation begin?
- Development begins in infancy but limited  Reliance on caregiver soothing  Continues to develop throughout childhood/adolescence
81
When does self-soothing begin in infants?

84
What is attachment?
“Lasting psychological connectedness between human beings” (Bowlby, 1969, p194)
85
What does Freud think about the early mother / child bond?

86
What is the learning theory?
- Mother associated with food - ‘Cupboard Love’
87
What is the Harlow's Monkeys experiment?
- Tested hypothesis that food drive is basis of attachment - Rhesus monkeys raised by two mothers  Wire mother  Cloth mother - Half monkeys received food from wire mother - Hald from terry towelling mothers - Harlow found - Monkeys preferred cloth mother in both cases - When frightened monkeys ran to cloth mother - Comfort not food basis bond
88
What is Bowlby's attachment theory?
- John Bowlby (1907 – 1990) - WWII Medic, Psychoanalyst, and active researcher - After WWII, commissioned by the World Health Organization to investigate the problem of orphaned infants
89
What was the conclusion of the WHO report on attachment theory in partnership with Bowlby?
“What is believed to be essential for mental health is that the infant and young child should experience a warm, intimate and continuous relationship with his mother (or permanent mother-substitute) in which both find satisfaction and enjoyment” (Bowlby, 1951/1971, p.12).
90
What was Bowlby's attachment theory findings?
- Drive for “felt security” - The development of the “Secure Base” - Individual Differences in attachment - Biologically rooted
91

- Signalling behaviours  Crying  Smiling - Kewpie faces  Facial features commonly associated with infants  Large forehead, wide-spaced eyes, a small chin, and delicate facial features
92
What is attachment?
the emotional bond formed between an infant and their primary caregiver(s), typically developing in the first year of life - Suggests that infants seek proximity to their caregivers for protection and comfort - Emphasises the importance of early relationships in shaping later social and emotional functioning
93
What is social development?
‘Social development changes over time in the child’s understanding of attitude to, and action with others’ (Hartup, 1991)
94
What are learning theories?
Focus on how individuals acquire new behaviours or knowledge through experience and practice

'Little Albert' experiment ?
98
What is operant conditioning?
- Learning by reward and punishment (Skinner, 1971) - If you do an action & rewarded, more likely to do it in the future
99
What are the insights of operant conditioning?
- Attention as a reward - ‘Time-out’ - Importance of the schedules of reinforcement
100
What are the limits of operant conditioning?
- Not all learning can occur this way
101
Who was Albert Bandura?
- One of the most highly cited psychologists of all time - Influential in Social cognitive theory, therapy, and personality - Highly influential for the transition from behaviourism to cognitive psychology - Developed social learning theory (now called social cognitive theory)
102
What is emphasis on observation learning?
- We don’t have to be directly rewarded, just observe it
103
What were the insights of Bandura's theory?
Children learn by following models Bobo Doll
104
What was the method of the Bobo doll experiement?
- Three groups of pre-school children watched 3 different films of aggressive acts 1. Actor rewarded for acts 2. Actor punished for acts 3. No consequences - Children then placed in room with Bobo doll - Observed to see what would happen
105
What were the results of the Bobo Doll experiment?
1. Actor rewarded for acts 2. Actor punished for acts 3. No consequences - Groups 1 and 3 produced most aggressive behaviours - Boys more than girls - All groups produced aggression if rewarded - Example of observational learning - Very influential on research, parenting, learning practices - Supports Bandura’s Social Cognitive Theory
106
What are the limitations of the bobo doll experiment?
- Ecological validity - Cumberbatch (1990) – novelty of the doll - Long term effects on children’s behaviour?
107
What are the social cognitive theories?
- Emphasis on observation of others - But also - Child is active in their own development - Can we focus on understanding how the child processes the information they encounter? - How do the children process information and problem solve?
108
What is the social information processing theory?
- Evaluated social problem solving in children - Children interpret situations based on past experiences - Including home environment and peer relations
109
What are the 6 stages to problem solving?
1. Encode a problematic event 2. Interpret the social cues involved in it 3. Formulate a goal to resolve the incident 4. Generate strategies to achieve the goal 5. Evaluate the likely success of potential strategies 6. Enact a behaviour - Measured responses to ambiguous situations
110
What is the evidence of hostile attribution bias?
 Children tend to interpret ambiguous social cues as hostile or threatening, leading to aggressive responses
111
What is meant by a self-fulfilling prophecy in terms of social information processing theory?
 When children consistently interpret social cues as hostile and respond aggressively, it reinforces their belief that others are hostile
112
What are gender roles within childhood?
- Expectations about behaviour patterns specific to each gender - Boys in blue, girls in pink - Boys interested in things, girls in feelings
113
What is the sociobiological theory? In terms of gender?
Gender is purely biological (adaptive differences between sexes)
114
What is the cognitive developmental theory in terms of gender?
children understand gender as cognition develops. Gender identity becomes stable over time (Kohlberg, 1966)
115
What is the social learning theory in terms of gender?
Children learn gendered behaviours through observation, reward and punishment (Bandura, 1977)
116
What did Smith and Llyod do?
- Investigated the influence of adult expectations on children's play behaviour. - Child dressed in gender neutral clothes - Adults conformed to stereotyped interactions more when they knew the gender - Adults' awareness of a child's gender influenced their behaviour and interactions - Highlights the role of social expectations in shaping children's experiences and opportunities for play.
117
What about gender roles in picture books? What did LaDow do?
- 125 picture books representing the work of 100 authors - Analysed: - The percentage of males or females represented in the titles, main characters, illustrations - Roles and activities of adults - Activities of children.
118
What was the gender representation in the picture books (LaDow)?
- 40% of the illustrations contained only male characters - 11 % contained only female characters
119
What gendered roles were depicted in the picture books? LaDow?
- Male characters depicted 81 different roles while female characters depicted only 17 different roles (e.g. caregiving roles for females)
120
What did the Gooden and Gooden (2001) study show in terms of gender in books?
- Females were listed as the main character 40% of the time and males in 39% of the titles analysed - Male characters depicted 25 roles, whereas female characters depicted 14 roles - “Although most of the women’s roles were traditional ones (mother, grandmother, washerwoman, etc.), they were finally seen as doctors, chefs, and even milk vendors.”
121
What about aggression and gender?
- Are boys more aggressive than girls? - Intentions  instrumental/hostile - Behaviours – physical – rough and tumble/ aggressive - Consequences Boys 3 times more likely to be directly aggressive than girls (Card et al., 2008, findings from 148 studies)
122
Why are boys more aggressive than girls?
- Testosterone (Book et al., 2001) - Genetic influences (Ferguson, 2010)
123

- Physical aggression - Relational aggression (Archer, 2004) - Aims at damaging social status or relationships - Generally, more common in girls
124
Why is relational aggression more common in girls?
- Societal demands - Different socialising patterns - Media influences (“Mean Girls”)
125
What is developmental psychology?
- Developmental psychology focuses on how people change throughout the lifespan ➢ What is the trajectory/history? ➢ Is this change continuous development, or is it in specific developmental stages? ➢ What causes the change?
126
What is adolescence?
- When does childhood end and adulthood begin? - Adolescence is a transitional stage between childhood and adulthood - Marked by physical, psychological, and social changes linked to puberty - Often associated with the teenage years, but development starts earlier and can continue into the 20s - The WHO definition: Ages 10-19, but this is a broad and debated range
127
Is adolescence universal?
- In some cultures, childhood ends with a clear rite of passage (e.g., bar/bat mitzvah, quinceañera, initiation rituals). - In Western societies, adolescence has lengthened due to prolonged education and delayed financial independence. - Some researchers suggest "emerging adulthood" (Arnett, 2000) is another division of development for ages 18-25, where identity exploration continues.
128
What about puberty and adolescents?
- Some define adolescents with the start of puberty - Puberty: a biological process that leads to physical and hormonal changes, preparing the body for sexual maturity and reproduction. Marked by:  Physical growth (height and weight) accelerates  Maturation of primary sex organs  Differentiation of secondary sex characteristics  Hormonal changes (females: oestrogen; males: testosterone) - Average onset : 8-14 in females, 9-15 in males (Blakemore et al., 2010, but large individual difference caused by genetic and environmental influences (Kauffman, 2010)
129
What is the Gillick competency test?
Both Gillick competency and Fraser guidelines refer to a legal case form the 1980s which looked at whether doctors should be able to give contraceptive advice or treatment to young people under 16-years-old without parental consent” – this is if they pass the Gillick competence test then they are able to receive this without competence - Based on a court case in 1986 - How does one assess “maturity” and “understanding of risks”?
130
What is meant when we say that brain development is 'protracted'?
- These are white matter tracts - General structures are present in babies - Continued development into adulthood - New studies  even as late as 35 years
131
What are synapses?
- Individual brain cells are called ‘neurons and the gap between them are called ‘synapses’ - Signals are produced in the cell body (soma) and travel down the axon as electrical signals - These are converted to chemical signals (neurotransmitters) to pass over the synaptic gap
132
What is the definition of a synapse?
The junction between one neuron and another
133
What is synaptogenesis?
Formation of new connections between neurons
134
What is synaptic pruning?
Regulatory elimination of these connections
135
How is pruning different from neuronal loss with aging?
 Pruning in adolescence is distinct from neuronal loss in aging  It is based on learning and experiences  ‘Use it or lose it’ principle and makes brain more efficient at its chosen tasks
136
What is gray matter and it's role?
- Gray matter = cell bodies and unmyelinated axons  The areas that are doing the ‘thinking’
137
What is white matter?
- White matter = myelinated axons  The cables connecting the different brain areas together
138
What is myelination?
- Myelin is a fatty tissue which coats the outside of the axon - Provides insulation for the neurons and makes nerve impulses more efficient - Information travels around 100 times faster through a myelinated than an unmyelinated axon
139
What is synaptic pruning?
- The first change after synaptic growth during fetal development is selective synaptic pruning - In adolescence, most pruning is taking place in the frontal lobes - Adolescents lose approximately 3% of gray matter in the frontal lobes
140
In adolescence where does most synaptic pruning take place?
Frontal lobes
141
How has a higher volume of grey and white matter - adolescents or children?
- Adolescents have a higher volume of white matter and a lower volume of grey matter compared to children.
142
When does synaptogenesis peak?
- Synaptogenesis peaks in early childhood, while synaptic pruning continues into the 20s.
143
What areas of the brain are last to develop?
- The areas which control ‘executive functions’ (i.e. impulse control, planning) are among the last to mature and this can happen in the 20s
144
What are Piaget's stages?
Sensorimotor Preoperational Concrete operational Formal operational
145
What is the sensorimotor stage?
- Sensorimotor (0-2 years): object permanence and separation anxiety develop during this stage.
146
What is the preoperational stage?
- Preoperational (2-6 years): child capable of symbolic thought and pretence but lacks ability to reason logically.
147
What is the concrete operational stage?
- Concrete operational (6-12 years): can reason logically about concrete objects and can thus begin to perform mathematical operations.
148
What is formal operational?
- Formal operational (12 years+): can reason logically about abstract concepts and can think in hypothetical terms.
149
According to Piaget what does the formal operational stage represent?
- According to Piaget, the formal operational stage represents the shift from concrete to abstract and symbolic thought
150
What is the third eye problem?
 Third eye problem (‘if you had a third eye, where would you put it?’ A test of formal operational thought
151
What is the Pendulum problem?
 Pendulum problem (‘what governs the speed of a object swinging on a piece of string A test of formal operational thought
152
What age does formal operational thought typically develop?
Aged 15
153
What is basic cognitive capacity and when is it fully developed?
- Basic cognitive capacity is fully developed by mid-adolescence: e.g. processing speed and short-term memory span. - However, some cognitive functions continue to improve e.g. creativity, episodic long-term memory (use more efficient strategies, become better at inhibiting irrelevant information).
154
What are some key executive functions?
- Key executive functions include:  Planning ahead  Inhibitory control  Switching between tasks  Updating the working memory
155
What is inhibitory control?
- Inhibitory control improves across adolescence and into adulthood (Schel and Crone, 2013; Crone et al, 2018). - Helps control impulsive behaviour. - Slower to develop in more deprived communities.
156
What is working memory?
- Working memory matures into adulthood. - Improvements result in quicker and better decision-making. - Working memory in adolescence may be boosted by mindfulness interventions (Quach et al., 2015) and music practice (Nutley et al., 2014).
157
What did Tamnes et al. (2013) find in their study?
- Longitudinal study of individuals aged 8- 22. - Completed working memory updating task and structural MRI twice, 2.5 years apart. - Findings: Improvement in memory updating associated with reduction in frontal lobe volume.

What is the link between adolescents and sleep?
- Sleep is needed to support the neurobiological changes during adolescence - A critical period of development (Larsen & Luna, 2018) - However, adolescents are getting less sleep! - The percentage of adolescents sleeping more than 7 hours per night is less than 40% (Keyes et al., 2015) - But when undisturbed, adolescents typically sleep over 9 hours per night (Carskadon, 2011)
159
What is inconsistent sleep associated with?
- Inconsistent sleep is associated with reduced frontal lobe gray matter thickness and poorer inhibitory control in adolescents (Lapidaire et al., 2021).  Catching up on sleep on weekends was associated with increased white matter density and increased emotional control in adolescents (Guldner et al., 2023) - Different effects for males vs. females! Sleep deprivation has a stronger effect on executive functioning in male adolescents than females (Kuula et al., 2015).  Individual differences may exist! - Sleep may be a protective factor in managing the adolescent critical period of brain development!
160
Why do adolescents experience increased emotional intensity?
- Increased emotional intensity: adolescents experience emotions more intensely due to heightened limbic system activity
161
Why are adolescence more emotionally volatile?
Mood swings become more common due to hormonal fluctuations (testosterone, oestrogen, cortisol)
162
What is the imaginary audience effect?
- Heighted self-consciousness: adolescents become more aware of how they are perceived by peers, often leading to social anxiety  ‘The imaginary audience’ effect – many adolescents believe others are constantly watching and judging them, which can influence their behaviour (Elkind, 1967)
163
What was the Larson et al. (2002) study?
- Larson et al. (2002) – longitudinal experience sampling study - Participants: 200 youth, surveyed at random times for one week, then again for one week 4 years later - Findings:  Emotional states become less positive across early adolescence  Decline in positive emotions stopped by grade 10 (suggesting stabilisation in late adolescence)
164
What happens to emotions between the ages of 12 and 18?
- Between ages 12-18: (Zemen et al., 2006)  Greater awareness of emotions and their consequences  Increase in self-conscious emotions in frequency and intensity (e.g. shame, embarrassment, pride)  More complex emotion regulation strategies emerge - Adolescents experience heightened emotional self-awareness and an increase in self-conscious emotions, influencing their social and psychological development
165
What did Garnesfski discover?
- Increase in cognitive coping strategies to manage negative emotions across adolescence.
166
What are some adaptive strategies?
 Positive reappraisal (rethinking a situation in a more positive way).  Refocus on planning (developing strategies to deal with stress).
167
What are some maladaptive strategies?
 Rumination (dwelling on negative feelings).  Self-blame (placing excessive responsibility on oneself).
168
Increased social anxiety in adolescence
- Increased social anxiety: greater fear of judgment and rejection, particularly in peer settings - Peer relationships become less activity-focused in adolescence
169
What happens to independence in adolescence?
- Stronger desire for independence: shift from family-oriented to peer-focused social structures  Achieving mature peer relations  Achieving independence from adults
170
What about risk taking in adolescence?
- Greater risk-taking: more likely to engage in thrill-seeking behaviours due to an imbalance between the limbic system (emotion) and the prefrontal cortex (regulation)(Steinberg, 2007)
171
What about identity exploration in adolescences?
- Identity exploration: Adolescents experiment with different roles, values, and beliefs as they form a sense of self (Kroger, 2006)  Greater exploration of intimacy and relationships
172
What was the social media study by Cingel & Krcmar, 2014?
- How is Facebook use related to Imaginary Audience ideation (the belief that others are constantly watching and judging)? - Participants: 9-26 years
173
What did the social media study by Cingel & Krcmar, 2014 find?
- Facebook use is positively associated with Imaginary Audience ideation  Adolescents who used Facebook more were more likely to feel watched or judged - The more adolescents engaged in social comparison and strategic self-presentation, the stronger their imaginary audience perception - Self-consciousness and social media behaviours are intertwined  Adolescents who frequently thought about their self-presentation also engaged in image control online
174
What was the study of peer rejection carried out by Sebasitain?
- Study of peer rejection using Cyberball and fMRI (Sebasitain et al.m 2011) - Cyberball task  Participants play a virtual ball-toss game; eventually, they are excluded by the others: (controlled by researchers) to simulate rejection
175
What were the findings of the peer rejection study by Sebasitain et al., 2011
 Adolescents’ distress  Higher distress from social exclusion than adults  Brain activation (MRI results)  Greater activation in the medial prefrontal cortex (mPFC) during social exclusion
176
What happens to peer relationships in adolescence?
They become more important
177
Peer relationships - development of identity?
- Key in development of identity  Friendships provide social support and sense of belonging
178
Peer relationships - based on intimacy/self-disclosure
- Often based on intimacy/self-disclosure  Change from earlier focus on shared activities seen in childhood
179
Do peers have negative influence in adolescence?
 Depends on the peers and environment  Tend to be more positive than negative.  Positive: emotional support, intimacy  Negative: bullying, encouraging risk
180
What happens to attachment to parents in adolescents?
- Attachment to parents  Adolescents still seek security and support, but independence increases.  A shift occurs toward a balance between attachment and exploration
181
What about conflict with parents in adolescence?
 Some conflict with parents is common – but not for everyone!  Intensity and frequency of conflict peak in early adolescence and decline by late adolescence.
182
What factors shape parent-adolescent relationships?
 Early attachment patterns and child temperament influence adolescent relationships.  Warm, responsive parenting predicts stronger bonds and healthier adjustment.  Authoritative parenting (high warmth + firm guidance) fosters independence and well-being.
183
What about troubled parent-adolescent relationships?
 Chess & Thomas (1984):  Adolescents in conflict-prone relationships fare best when parents remain calm but firm.  Excessively harsh or permissive parenting can worsen behavioural issues.
184
What are the two key dimensions of parenting styles?
Responsiveness (warmth) Demand-control (control)
185
What is responsiveness (parenting)?
 Supportiveness & sensitivity to need
186
What is demand-control (parenting)?
- Most successful parenting style: authoritative - Exercise power: reasonable set of rules - Also responsive to needs - Supportive and flexible
187
What are the outcomes of authoritative parenting?
Linked to better adolescent adjustment across cultures - Predicts:  Higher confidence & cooperation  Lower delinquency & trouble  Better mental health  Improved school performance
188
What did the Kerr et al., (2012) longitudinal study show?
 Found that adolescent adjustments predicts changes to parenting, rather than the reverse  Good parenting is adaptive – parents adjust to their approach their approach based on their teen’s needs
189
What influence does authoritative parenting have on risk taking?
 Linked to lower risk-taking behaviours (moderate control + emotional support).
190
What did the Piko & Balazs (2012) study show?
 Examined smoking and drinking behaviours in 2,000+ 12- 22-year-olds. - Findings:  Low emotional responsiveness from parents linked to higher risk-taking.  Lack of identification with parents and negative family interactions also predicted higher risk-taking behaviours. - Parental relationships and parenting styles may be a risk factor for risky behaviours in adolescents
191
What did the Chein et al., study show in terms of peer influences on adolescent risk-taking?
- Adolescents took more risks when peers were watching (Peer condition). - fMRI results: Adolescents showed higher activity in reward-related brain regions in the Peer condition - Cognitive control brain regions (prefrontal cortex) were less active in adolescents compared to adults, but did not change with peer presence.
192
What was the Chein et al., (2010) study?
- Does the presence of peers increase risk-taking in adolescents? - Participants completed a driving-simulator task in two conditions:  Alone (no observers)  Peer condition (friends observed from another room – surprise condition!) - Participants:  Adolescents (14–18 years)  Young Adults (19–24 years)  Adults (24–29 years)
193
What is the Analogue Risk Task ?
Participants inflate a virtual balloon, earning money for each inflation. The risk is that the balloon might pop, causing them to lose all money accumulated.
194
What were the findings of the Balloon Analogue Risk Task?
Adolescents (14-18 years) show higher risk-taking, inflating the balloon more times compared to adults and children. This supports the idea that adolescence is a peak period for risky behaviour.
195
Do all risky behaviours peak in adolescence?
Yes. - Higher risk-taking in adolescence than children or adults  Criminal behaviour, drugs, reckless driving, dangerous sports, antisocial behaviour…..  But still only minority teenagers
196
What was Casey's Theory?
Proposed that this mismatch between the fast development of the limbic system and the slow development of the prefrontal cortex Adolescents are more likely to seek out rewarding experiences (e.g., peer approval, excitement, novelty) because their limbic system is highly responsive. Because the prefrontal cortex is still maturing, adolescents may not fully anticipate the consequences of their actions
197
What was the Telzer et al., 92015) study?
- Telzer et al. (2015) - Assessed peer conflict and risk-taking - Participants: Adolescents 15-17 years completed the BART

199
What is the Diagnostic and statistical manual of mental disorders (DSM - 5)?
- 5th edition of the American Psychiatric Association’s manual for identifying conditions - A classification system for identifying, diagnosing, and treating mental health conditions - Used by clinicains, researchers and policymakers worldwide
200
Why are there so many editions of DSM?
- Mental health understanding evolves over time (e.g. homosexuality was a disorder in DSM-I, 1952) - New research leads to updated definitions and criteria - Each edition reflects shifting cultural and scientific perspectives
201
What are the five main criticisms of DSM-5?
Lack of empirical support – Some diagnostic categories are not strongly backed by research Low interrater reliability – Clinicians often disagree on diagnoses for certain disorders Influence of Big Pharma – Concerns that pharmaceutical companies shape diagnostic criteria Culturally biased – Based largely on Western norms, potentially misdiagnosing diverse populations Medicalizes normal experiences – Expands diagnostic categories to include everyday struggles (e.g., grief vs. depression)
202
What are four strengths of the DSM-5?
- Incorporates practical knowledge – Draws from extensive clinical experience and case studies - Refinement of material – Refined criteria for certain disorders (e.g., autism spectrum changes) - A useful “one-stop shop” – Standardized tool for diagnosing mental disorders - Common ground for clinicians & researchers – Creates a shared language for mental health professionals
203
What is normal?
Normal’ changes over time and across contexts  DSM: Homosexuality classified as a disorder until 1973  Left-handedness once seen as a disability or defect
204
What effect does culture have on defining normal?
 Culture matters: some behaviours considered disorders in one society are seen as strengths or spiritual gifts in another
205
What effect does environmental matters have on what is normal?
 Environment matters: a trait that’s problematic in one setting may be an advantage in another (e.g. ADHD in school vs. entrepreneurship)
206
What is normal?
- ‘Normality’ is not a fixed concept – it depends on historical, cultural, and situational context - Labels shape perception – once diagnosed, behaviour is interpreted through that lens  E.g. ‘Sane in insane places’ study (Rosenhan, 1973)
207
What was the objective of the Being sane insane place study ?
- Examine the validity of psychiatric diagnoses by determining if mental health professionals could distinguish between ‘sane; and ‘insane’ individuals  Note: language used to describe mental illness is now unconventional
208
What was the method of the being sane in insane places study?
- Eight ‘pseudo-patients’ (including Rosenhan) feigned auditory hallucinations to gain admission to 12 different psychiatric hospitals - After admissions, they behaved normally and reported no further hallucination
209
What are the findings of the being sane in insane places study?
- All were admitted with diagnoses of paranoid schizophrenia. - Hospital stays ranged from 7 to 52 days (average 19 days). - Staff failed to identify the pseudo-patients as impostors; however, some actual patients suspected the truth. - All patients were eventually discharged - Labelled “remitted schizophrenia” upon discharge
210
What were the conclusions of the being sane in insane places study?
- Labels stick: Once diagnosed, normal behaviour was interpreted as pathological - Power of context: The hospital environment shaped perceptions of behaviour
211
What was the challenge that was given to Rosenhan after his being sane in insane places study?
- A hospital doubted Rosenhan’s findings and claimed they could detect pseudo-patients
212
What was the procedure for this being sane in insane places follow up study?
- Rosenhan informed the hospital that pseudo-patients would attempt admission over the next three months - Staff were asked to rate each new patient on a 10-point scale regarding the likelihood of being a pseudo-patient
213
What were the results of the being sane in insane places follow up study?
- Out of 193 patients, 41 were suspected as ‘imposters’ by at least one staff member - But no pseudo-patients were sent
214
What is neurodiversity?
- The idea that everyone has unique cognitive, behavioural, and emotional differences - Conditions like autism and ADHD are just variations in human functioning rather than deficits
215
What is the medical model of neurodivergence?
View neurodivergence as a disorder or deficit that needs to be diagnosed and treated. Focuses on symptoms, deficits, impairments, and possible interventions e.g., ADHD is seen as an inability to focus
216
What is the social model of neurodivergence?
Sees neurodivergence as a natural variation in human thinking and behaviour. Challenges the idea that difficulties arise from the individual rather than societal barriers. e.g., Instead of "fixing" an autistic person’s sensory sensitivities, environments could be adjusted (e.g., quiet spaces, flexible work policies).
217
What is Autism?
- A neurodevelopmental condition affecting social interaction, communication, and behaviour. - Exists on a spectrum—each autistic person has unique strengths and challenges.
218
What features of autism are laid out in DSM-5?
Differences in social communication (e.g., difficulty with eye contact, interpreting social cues). Repetitive behaviours & special interests (e.g., routines, deep focus on specific topics). Sensory differences (e.g., heightened or reduced sensitivity to sounds, lights, textures).
219
What are gender differences in autism ?
Males are 4 x more likely to be diagnosed than females Ongoing debate about why Do males actually have autism more often? Or are males easier to diagnose due to more ‘textbook’ presentation? Autistic females may mask their traits, leading to underdiagnosis or misdiagnosis (e.g., as anxiety or social difficulties)
220
What was the Watson et al. (2013) study?
- Recruited children (ASD & control group) aged 2 to 7 years. - Parents provided retroactive home videos from infancy at 2 time points (9–12 months & 15– 18 months). - Researchers analysed early social behaviours to identify early signs of autism
221
What were the findings of the Watson et al study?
- Differences in early social behaviours - Joint attention: Less likely to follow gaze or point to share interest. - Behavioural regulation gestures: Fewer gestures like waving or reaching to request help. - Social interaction: Less eye contact, smiling, or back-and-forth interactions.
222
Are genetics a risk factor of autism?
- Genetics – multiple interacting genes play a role rather than a single gene (Sandin et al., 2017)
223
Are brain differences predictors of autism?
- Brain differences – increased neuron proliferation in frontal lobes (Benaron, 2009)
224
What are perinatal influences of autism risk?
- Perinatal influences – factors during pregnancy  Parental age – older parents = slightly higher likelihood  Pregnancy complications – e.g. exposure to toxins, infections in utero
225
What does not cause autism?
- Neglectful parenting – the outdated ‘refrigerator mother’ theory has been thoroughly disproven - Vaccines – the claim that MMR causes autism has been scientifically debunked - Post-natal toxins/infections – autism develops before birth, not due to environmental exposure after birth
226
What is Applied Behavioral analysis?
- A controversial type of therapy - Focuses on modifying behaviours using principles of reinforcement and punishment.  Developed from B.F. Skinner’s operant conditioning theories.  Can cause distress for the individual - Often used to teach communication, social skills, and daily living activities  Can improve communication and social skills for some children with autism.
227
What are the DSM - 5 features of ADHD?
- Inattention (6+ months, inappropriate for developmental level) - Hyperactivity & Impulsivity (6+ months, inappropriate for developmental level) - Symptoms must be seen in at least two settings (e.g., home, school, work) - Symptoms significantly impact daily life (social, academic, or occupational functioning) - Not better explained by another condition - Symptoms appear by age 12.
228
What are some risk factors and predictors of ADHD?
- Genetics – highly heritable! - Brain developmental differences – structure & function of frontal lobes linked to inhibitory problems, imbalance of neurotransmitters (Barkley, 2006) - Prenatal influences – factors during pregnancy  Pregnancy complications (e.g. exposure to toxins, infections in utero)
229
What treatment and support is available for children with ADHD?
- Classroom management: feedback, planned ignoring, time-out, daily reports, adapting educational materials - Psychosocial intervention: child and parent behaviour training and support
230
What treatment and support is available for adults and children with ADHD?
- Drug treatment (e.g. Ritalin and ither stimulants) - Physical exercise: positive effects on cognitive symptoms (Lambez et al., 2020) - Cognitive Behavioural Therapy (CBT): learning coping skills
231

232
What are the Key features of preschool depression?
 Irritability, withdrawal, loss of pleasure.  Lack of attachment, parental depression, and increased risk for later depression.
233
What is childhood depression?

236
What are some interventions for adolescent depression?
Anti-depressants Cognitive behavioral therapy
237
What affect do anti-depressants have on adolescent depression?
 Do improve symptoms in severe depression.  May have side-effects: controversy about suicidal thoughts.
238
What affect does cognitive behavioral therapy have on adolescent depression?
 CBT effective in mild-moderate depression.  More effective than anti-depressants  Effective in mental health and social work settings.
239
When does neuronal loss occur?
 Older adults have fewer neurons than younger adults  About 5-10% fewer neurons at age 65 than at age 20
240
What is neurogenesis and when does it occur?
 Neurogenesis (new neurons) can still occur especially in the hippocampus (important for memory)  Brain remains plastic (changeable) even in later life
241
What are neurofibrillary tangles?
 Occurs inside neurons as tau protein begins to deform and tangle  Associated with Alzheimer's disease, but also increases naturally with age
242
What are amyloid plaques?
 Occurs outside of neurons as clumps of dead/dying neurons and proteins accumulate  More common with age, even in people without dementia
243
Where, how and why does brain shrinkage happen?
 Especially in the frontal lobes  Shrinkage is due to natural aging  Could be related to mini-strokes (infarcts) and accumulated small traumas
244
What declines more, white or grey matter?
 White matter (the brain’s communication highways) declines more than grey matter (neuron bodies). This affects how efficiently brain areas talk to each other
245
What functions are carried out by the frontal lobe?
- Many age-related cognitive changes are linked to frontal lobe - Especially affects executive functions: planning, multitasking, inhibiting distractions
246
What is retrogenesis?
Last in, first out.
247
What is the hippocampus?
- A small, seahorse-shaped structure deep in the brain - Crucial for forming new memories and for spatial navigation - One of the first regions affected in Alzheimer’s disease - There are two structures (on each side of the brain) that comprise the hippocampus
248
What does age do to the hippocampus?
- The hippocampus shrinks as we get older - This shrinkage reflects loss of neurons and connections - Studies show accelerated shrinkage in older age (Fjell et al., 2013)
249
How does a smaller hippocampus affect memory?
- Smaller hippocampal size is linked to poorer memory - In a study of adults aged 81-94, those with smaller hippocampi had more memory impairments (Lye et al., 2004)
250
What can blood flow tell us about brain activity?
- Blood flows closely linked to brain activity. - When a brain region is active, it needs more oxygen and nutrients, which increases blood flow to that area. - So, by measuring blood flow, researchers can infer which areas of the brain are working harder during tasks.
251
What did the Spreng et al., (2010) study show at rest?
 Older adults have lower frontal lobe blood flow than younger adults  Suggests reduced baseline activation of frontal love with age
252
What did the Spreng et al., find during cognitive tasks?
 Older adults show higher frontal blood flow compared to younger adults  Indicates they are recruiting more frontal resources to complete complex tasks
253
What is short-time memory?
- It’s the system that lets us hold a small amount of information for a short time (up to 30 seconds – 1 minute)
254
What is the capacity of short-term memory?
 Limited to around 5-9 items (Miller’s “Magic number 7 ± 2”)  You can test this with the digit span task:  Listen to a sting of numbers and repeat them back
255
Does short-term memory decline with age?
- Not much - Digit span scores stay relatively stable into older adulthood - This suggests that the basic ability to hold small amounts of information is preserved even as other types of memory change
256
What is working memory?
- More than just short-term storage - WM lets us hold information in mind while actively using it
257
How do we test working memory?
- Use of tasks where information needs to be manipulated or processed simultaneously
257
What is working memory essential for?
- Reading comprehension (remembering what you just read while processing the next sentence) - Mental arithmetic (holding numbers in your head while calculating) - Conversation (keeping track of what's being said while planning your response
258
What happens to working memory with age?
- Older adults show declines in working memory capacity - Especially when tasks require simultaneous storage and processing.
259
What is long term episodic memory?
- Memory for events - Involves remembering what happened, where and when - E.g. remembering items from a shopping list or what you did last weekend
260
What happens to long-term episodic memory with age?
- Episodic memory often shows early and noticeable decline with age - In lab studies, older adults tend to:  Recall fewer items from word lists  Make more intrusion errors (recalling words that weren’t on the list)  Use fewer effective strategies, like mental imagery or chunking
261
What is long-term autobiographical memory?
- Memory for your personal life history - Combines episodic memory (specific events) and semantic memory (general facts about your life)  E.g., remembering what happened on your 18th birthday and where you celebrated it.
262
How does long term autobiographical memory change with age?
- Well preserved in older adults! → Especially for early childhood memories - This supports the "reminiscence bump" – a tendency to recall more memories from youth and early adulthood
263
Explain the case of Jeanne Calment...
- Jeanne Calment showed high autobiographical memory accuracy even at age 118 through neuropsychological testing (Ritchie, 1995)
264
What is long term procedural memory?
- Memory for how to do things - Acquired skills retained in memory - E.g., Riding a bike - Usually remains intact with age—even in older adults with cognitive decline
265
What is long-term semantic memory?
- Memory for facts - E.g., how to spell your name - Usually remains intact with age (may even improve!)—even in older adults with cognitive decline
266
What happens to prospective memory as we age?
- Consider: Prospective memory - Prospective memory: Memory for future intentions; remembering to carry out a task at the right time  E.g., Remembering a doctor’s appointment Henry et al. (2004) meta-analysis found an “age paradox”: - In the lab: Younger adults outperform older adults on prospective memory tasks - In real life: Older adults often do better than younger adults!
267
What is intelligence?
 The capacity to learn from experience and adapt to the environment
268
What two types of intelligence did Horn and Cattell's Theory (1967) propose?
Fluid intelligence Crystallized intelligence
269
What is fluid intelligence?
- Ability to solve novel problems without relying on prior knowledge - Ability to be flexible and adaptive - E.g. figuring out a new phone, solving Sudoku
270
What happens to fluid intelligence as we age?
- Peaks in early adulthood, then declines with age
271
What is crystallized intelligence?
- Accumulated knowledge and experience - E.g. Knowing historical facts, offering advice, using rich vocabulary, vocabulary test - Dependant on culture
272
What happens to crystalized intelligence as we age?
- Remains stable or improves with ages
273
What is cognitive reserve?
 Brain’s resilience to age-related decline or damage.  Helps explain why some people maintain mental sharpness despite brain aging or pathology.
274
What factors link to greater cognitive reserve?
 Education: Higher levels of education  Complex careers: Jobs that challenge thinking and decision-making  Mentally and socially stimulating activities: e.g., Book clubs, travel  Good physical health and fitness  Strong attention and processing speed  Flexible personality: Open to new experiences and adaptable to change
275
What is brain training?
 Computerized tasks or apps designed to improve memory, attention, reasoning, or speed (e.g. Lumosity, BrainHQ)  Usually includes repetitive puzzles or games  Sometimes known as “brain games
276
What does research say about brain training?
 Short-term task improvement is common  People get better at the trained task  It is not transferable to tasks outside of the game metrics  No strong evidence that improvements transfer to:  Everyday memory  Decision making  Real-world cognitive functioning
277
How does exercise help our brain?
 Exercise increases blood flow to the brain  Promotes neurogenesis especially in the hippocampus  Triggers release of proteins that supports brain cell function.
278
What did Buchman et al. (2012), longitudinal study show?
 716 adults aged 60+, tracked over 4 years - Findings:  Those with higher physical activity:  Had slower cognitive decline  Showed a lower risk of developing dementia
279
What was the theory of socioemotional selectivity by Carstensen & Charles (2007)?
- Proposes that our motivational goals change with age - Young adults often see time as expansive  focus on learning, exploring, and preparing for the future - Older adults become more aware of limited time  focus on emotionally meaningful goals and experience in the present - This shift influences how older adults manage emotions, attention, and memory
280
What does socioemotional selectivity predict about older adults?
- Chose situations which maximise positive emotions - Be biased to attend to and remember positive information - Reappraise situations in a positive way - Regulate emotions to emphasise the positive
281
Does emotion become more negative or more positive as we age?
- Despite physical or cognitive decline, many older adults report greater emotional well-being - No decline – and sometimes an improvement – in life satisfaction - Supported by both cross-sectional and longitudinal studies - Found across cultures: UK, US, China, Nigeria - Lawton (1991):  Older adults (even 85+) often more content  Report less negative affect such as anger, anxiety and depression
282
What happens to anger as we age?
- Anger declines steadily with age  Older adults report significantly less frequent anger than younger adults  Possibly due to better emotion regulation and fewer social threats
283
What happens to sadness as we age?
 Less of a decline compared to anger  May reflect sadness being more tied to loss
284
What age period do adults have the lowest levels of anxiety?
- Lowest levels of anxiety reported by adults aged 60 and above - May reflect greater emotional regulation, life experience, or reduced daily stressors
285
When does happiness peak?
- Peak happiness reported between ages 65-79 - Possibility linked to retirement, more free time, and social connectedness
286
How does depression present in later life?
- Less frequently diagnosed in older adults compared to younger people - May be due to underreporting, stigma, or different symptom expression - Scottish data shows lower reported rates of depressive symptoms in older age groups (e.g., 65–74). - More common in women than in men across the lifespan
287
What is depression in older adults linked to?
 Caring responsibilities (e.g., for a spouse or grandchildren)  Chronic physical health conditions (e.g., arthritis, cardiovascular disease)  Social isolation, bereavement and reduced mobility
288
How does the prefrontal cortex affect emotion as we age?
- The prefrontal cortex helps with emotion regulation (e.g., reappraising situations) - Older adults often show increased prefrontal cortex activity when focusing on positive emotions  Suggests that the frontal lobe is recruited to improve emotion regulation (Mammarella et al., 2017)
289
How does the amygdala affect emotion as we age?
- The amygdala processes emotional information, especially fear and threat - In older adults, it becomes less reactive to negative stimuli, which may reduce distressing emotions experienced (Mather & Carstensen, 2005)
290
What was the task in the Mather et al., (2004) study?
: viewed pleasant, unpleasant, and neutral scenes while brain activity was measured (fMRI)
291
What were the findings of the Mather et al., (2004) study?
- Young adults: amugdala responded stongly to both pleasant and unpleasant images - Older adults:  Strong amygdala activity for pleasant images (same as young adults)  Reduced amygdala activity for unpleasant images → Suggests a reduced sensitivity to negative emotional content
292
What does contact with grandchildren do to grandparents mental wellbeing?
