questioning, songs and storytelling,
listening, asking questions and generated
conversations and stories.

26
Preterm infants
babies born earlier than 36 weeks - children born at 25 weeks have a little over 50% chance of surviving - however, because fetal development happens quickly, children born at 30 weeks have a 95% chance of survival - survival is the first step, followed by possible short and long term negative effects on psychological and cognitive functioning
27
Visual cliff
tests depth perception in infants
28
rooting reflex
sucking - helps infant begin feeding
29
moro reflex
"startle" - when infants lose support of their head - they reach their hands up and then in a hugging motion
30
grasping reflex
safely holding onto their caregiver
31
stepping reflex
leg straightens at onset of pressure on sore of foot
32
What are the different reflexes
rooting moro grasping stepping
33
synaptogenesis
forming of new synaptic connections - through infancy and childhood - together with synaptic pruning increase neural efficiency
34
synaptic pruning
loss of weak nerve cell connections, accelerates during brain development through infancy and childhood - together with synaptogenesis - increase neural efficiency
35
Kangaroo Care
- an interesting support that was designed for premies - baby takes as much time as it can tolerate outside of the incubator to do: - skin-to-skin contact of a parent and preemie - holding technique, chest to chest, in an upright position where the baby is only wearing a diaper on the parent's bare chest - non-invasive, supportive, and natural early intervention for preterm infants - four fold decrease in apnea - improves survival rates
36
Motor Development
Infants are born with a large set of automatic motor behaviours (reflexes) Sucking and rooting reflexes are essential for feeding ❖The Progression of Motor Development In contrast to reflexes, the development of motor skills is dependent on practice and deliberate effort. Most infants develop motor skills in a sequence. The ages indicated are averages - infants may develop any of these milestones a few months earlier or later than the average. Cross-cultural differences in development
37
Brain Development in Early Childhood
- Better working memory ❖Between ages 8 and 10, cognitive functions are increasingly localized in distinct neural systems ❖Prefrontal-cortical areas – rapid growth, increase in executive functioning skills ❖Left cerebral hemisphere more active – language and knowledge ❖Inner brain: Hippocampus – memory and images of space Amygdala – novelty and emotional information ❖Better capacity in terms of perceptual motor coordination Cerebellum – balance and control of body movement
38
Early Childhood - Physical Growth
Body growth slows after the first two years Child’s shape becomes more streamlined Wide range of growth Individual differences more apparent More adult proportions Loss of body fat compared to infants Skeletal changes continue: New epiphyses, or growth centers in which cartilage hardens into bone, emerge Teeth All primary by 3 years old Begin to lose around 5-6 years old
39
Infants - Motor Development

Most infants develop motor skills in a sequence. The ages indicated are averages - infants may develop any of these milestones a few months earlier or later than the average. Cross-cultural differences in development
40
Sensory Development
Human infants are born almost completely helpless and require extended care as they develop their senses, strength, and coordination. ❖ Five senses functional at birth but not fully developed. Hearing is better developed than vision. Can discriminate, prefer certain odours, and tastes. ❖The human face holds particular importance for newborns. Newborns will imitate the facial expressions of others. Newborns prefer to look at stimuli that look like faces, compared to stimuli that have all the same features but are scrambled so that they don’t look like faces
41
Fine Motor Development in Middle Childhood (6 to 12 years)
❖Advances in fine motor skills occur due to the amount of myelin in the brain increasing significantly between the ages of 6 and 8 ➢ Better finger dexterity, control, coordination and eye hand coordination ❖Children’ increase in fine motor development enables them to develop new interests: ➢ build model cars, braid friendship bracelets, learn to play musical instruments ➢ use of computers/ tablets and phones - (academics, and social media) ❖Printing and Writing – greater legibility ❖Drawing – greater organization, representation, and detail (more purposeful)
42
Adolescent Peer Relations
▪Adolescent self-image is formed by perceptions of one’s place in the social world ▪Acceptance by peers: ▪ Has a major impact on socialization ▪ Close affiliation with a high-status peer crowd protects against depression and other negative psychological symptoms ▪Poor peer relations: ▪ Related to high social anxiety ▪Types of Friends: ▪ Controversial status youth ▪ Aggressive kids who are either highly liked or intensely disliked by their peers ▪ This sort of youth is most likely to engage in antisocial behavior
43
Principles of growth and development
- continuous sequential process from conception to death = during the first year, growth is very rapid - growth levels off during the preschool and elementary-school years - growth is rapid again in early adolescence - not all body parts grow in the same rate at the same time - each child grows in his/her own unique way - each stage of growth and development is affected by the preceding types of deveopment
44
What are the physical growth trends?
Proximodistal trend Cephalocaudal trend Epiphyses
45
Proximodistal trend
- near to far - head, chest and trunk grow ahead of extremeties
46
cephalocaudal trend
head to tail - head develops more rapidly than lower part of the body
47
Epiphyses
- a physical growth trend - in pre-natal development, bones form as cartilage - shortly before birth turn into bone through epiphyses (hard at each end and middle)
48
Important aspects of development
- Development occurs in a relatively orderly sequence, with later abilities, skills, and knowledge building on those already acquired Example: crawl, pull to stand, steps, walking Example: cooing, sounds, approximations, words, phrases, sentences ❖Development proceeds at varying rates from child to child as well as unevenly within different areas of each child’s functioning Own pattern and timing of growth Unique personality, temperament and learning style Varied experiences and family background ❖Early experiences have both cumulative and delayed effects on individual’s development; optimal periods exist for certain types of development and learning Example: First 3 years optimal for verbal language
49
Infants- motor development
Infants are born with a large set of automatic motor behaviours (reflexes) Sucking and rooting reflexes are essential for feeding ❖The Progression of Motor Development In contrast to reflexes, the development of motor skills is dependent on practice and deliberate effort. Most infants develop motor skills in a sequence. The ages indicated are averages - infants may develop any of these milestones a few months earlier or later than the average. Cross-cultural differences in development
50
When does body growth slow?
after the first two years Child’s shape becomes more streamlined Wide range of growth Individual differences more apparent More adult proportions Loss of body fat compared to infants Skeletal changes continue: New epiphyses, or growth centers in which cartilage hardens into bone, emerge
51
Teeth
- All primary by 3 years old - Begin to lose around 5-6 years old
52
Brain Development in Early Childhood
Better working memory ❖Between ages 8 and 10, cognitive functions are increasingly localized in distinct neural systems ❖Prefrontal-cortical areas – rapid growth, increase in executive functioning skills ❖Left cerebral hemisphere more active – language and knowledge ❖Inner brain: Hippocampus – memory and images of space Amygdala – novelty and emotional information ❖Better capacity in terms of perceptual motor coordination Cerebellum – balance and control of body movement
53
Gross motor
Engage in more complex motor skills: Balancing Running Jumping Skipping Throwing Swinging Hopping ❖Greater balance, flexibility, speed and endurance
54
Fine motor
More dexterity Precise, delicate ❖Self-help skills Dressing Feeding Shoe tying ❖Gripping Use varied grips depending on task More developed by end of early childhood ❖Handedness About 90% right-handed
55
Brain development in middle childhood
The brain continues to grow and develop during middle childhood ❖Weight of the brain in middle childhood increases by 10%: ❖ White matter rises steadily, especially in the prefrontal cortex, parietal lobes, and corpus callosum ❖ Gray matter peaks in middle childhood and then declines as a result of synaptic pruning ❖Synaptic pruning and accompanying reorganization and selection of brain circuits lead to more effective information processing ❖Neurotransmitters and hormones may affect brain development and functioning
56
What happens to white and gray matter in middle childhood?
White matter rises steadily, especially in the prefrontal cortex, parietal lobes, and corpus callosum ❖ Gray matter peaks in middle childhood and then declines as a result of synaptic pruning
57
Fine motor development in middle childhood (6 to 12 years)
Advances in fine motor skills occur due to the amount of myelin in the brain increasing significantly between the ages of 6 and 8 ➢ Better finger dexterity, control, coordination and eye hand coordination ❖Children’ increase in fine motor development enables them to develop new interests: ➢ build model cars, braid friendship bracelets, learn to play musical instruments ➢ use of computers/ tablets and phones - (academics, and social media) ❖Printing and Writing – greater legibility ❖Drawing – greater organization, representation, and detail (more purposeful)
58
Adolescent growth spurt and puberty
Puberty marks the biological start of adolescence * Events and timing of sexual maturation differ for boys and girls - Adolescents become taller, heavier, and experience changes in both primary and secondary sex characteristics -
59
What regulates the timing of puberty
genes, nutrition, and health
60
Brain Development During Adolescence
- Brain almost adult size by adolescence ❖Synaptic pruning: less-used circuits eliminated ❖Myelination leads to greater efficiency ❖Decision-making areas of cortex mature slowly ❖“Pleasure centers” mature more quickly
61
Adolescent Peer Relations
▪Adolescent self-image is formed by perceptions of one’s place in the social world ▪Acceptance by peers: ▪ Has a major impact on socialization ▪ Close affiliation with a high-status peer crowd protects against depression and other negative psychological symptoms ▪Poor peer relations: ▪ Related to high social anxiety ▪Types of Friends: ▪ Controversial status youth ▪ Aggressive kids who are either highly liked or intensely disliked by their peers ▪ This sort of youth is most likely to engage in antisocial behavior
62
Cognition and cognitive development
Cognition Activity of knowing and the mental processes used to acquire knowledge and solve problems ❖Cognitive development Changes that occur in mental skills and abilities over the course of life
63
Piaget's theory of cognitive development
Stage-like theory, domain-general ❖Children construct their knowledge ❖Schema Cognitive structures or concepts used to identify and interpret objects, events, information in environment, an organized ways of making sense of experience . ❖ Children use assimilation to acquire new knowledge within a stage Absorb knowledge into current structures ❖ When a child can no longer assimilate new information, accommodation occurs Process of altering a belief to make it more compatible with experience ❖Organization and Equilibrium: Rearranging existing schema into more complex ones
64
Piaget's stages of cognitive development
Sensorimotor Preoperational Concrete operational Formal operational
65
Primary sex traits
changes in the body part of reproduction (menstration)
66
Secondary sex traits
changes in the body not a part of reproduction (ex. growth of pubic hair, muscle in boys and breasts in girls)
67
menarche
onset of menstruation (usually 12)
68
Cognitive reframing
strategy of dealing with emotions where we learn to look at our experience through a different frame - like turning something negative into a learning experience
69
Delaying gratification
putting off immediate temptations in order to focus on long term goals
70
formal operational thinking
abstract reasoning and logic and higher cognitive abilities (starts to go up after age 12)
71
formal operational thinking
abstract reasoning and logic and higher cognitive abilities (starts to go up after age 12)
72
Lawrence Kohlberg
moral development learning right from wrong
73
Levels of reasoning:
preconventional conventional postconventional
74
Preconventional reasoning
- people reason based on self-interest, avoiding punishment
75
Conventional reasoning
people reason based on social conventions (traditions), can involve authority figures "Because mom said so"
76
Post conventional level
Level of reasoning that considers justice and fairness
77
Sensitive periods
windows of time during which exposure to a specific type of environmental stimulation is needed for normal development of a specific ability ex. becoming fluent in a language --> should be introduced to that language in really early years
78
assimilation
fitting new information into the belief system you already posses ex. all girls have long hair - that person has short hair but is a girl! (azlan)
79
accomidation
creative process where people modify their belief structures based on experience ex. that girl has short hair, so girls can have short hair
80
Sensorimotor Stage
stage of cognitive development by Piaget - Birth - 2 yrs - cognitive experience based on direct sensory experience w world and motor movements - object permanence is the milestone of this stage - sensory inputs like vision and hearing and motor capabilities become more coordinated - infants develop sensorimotor schemes - this stage is further subdivided into six stages
81
sensorimotor scheme
An organized pattern of action (or behaviour) with which the infant interacts and comes to know the world. Examples: Sucking and Grasping
82
Object permanence
Understanding that objects continue to exist when they are not in sensory or motor contact with the object, as revealed by retrieval of hidden objects ❖*May be present within first few months - Renée Baillargeon’s studies - earlier than Piaget conceptualized. ❖Mastery is gradual, more complex with age as changes take place in the frontal and prefrontal cortex: Awareness not yet complete: A-not-B search error
83
A-not-B search error
A-not-B search error: continuing to search for an object in its first hiding place even after seeing it moved Full understanding revealed by problems involving invisible displacement
84
Preoperational stage
One of Piaget's stages of cognitive development - 2-7yrs - as children move from the sensorimotor to the preoperational stage, cognitive representational activity increases Use of symbols increases: symbolic function, symbolic/pretend play - children during this stage did not yet have the ability to think logically - mastering conservation - egocentrism
85
conservation
knowledge that the quantity or amount of an object is not the same as the physical arrangement and appearance of that object
86
Egocentrism
- during preoperational stage - focus only on their own viewpoint or perspective - unable to think about others' symbolic viewpoints from one's own (ex. if they see cows from their side of the mountain, they feel the child also sees the cows) - Piaget believed preschoolers' egocentric bias prevents them from accommodating or reflecting on and revising their limited reasoning
87
What are the two key aspects of conservation
Due to 2 key aspects: 1. Centration: focusing on one aspect of a situation while neglecting other important features 2. Irreversibility: an inability to mentally go through a series of steps in a problem and then reverse direction, returning to the starting point
88
transitivity
if you have more than her, and i have more than you, then I also have more than her
89
Concrete operational stage
One of Piaget's stages of cognitive development - 7-11 yrs - children develop skills in logical thinking and manipulating numbers (transitivity property) - now we are able to conserve (decentration - nolonger focus solely on one aspect and reversibility (can reverse thinking))
90
Strategies and rules that make thinking more systematic and powerful
These are used in concrete operational stage of cognitive development - numbers - categories of objects - spatial relations among objects - cognitive maps
91
Formal operational stage of cognitive development
11+ yrs - Piaget's final stage of cognitive development - children can think more rationally and systematically - they can think about abstract concepts and hypothetical events, using cognitive skills such as inductive reasoning Ex. start with a theory about what produces a particular outcome and then deduce explanations for specific situations in which they see that particular outcome -
92
What contributions did Piaget's Theory give us:
Helped us to understand that children are fundamentally different from adults – think differently within cognitive limitations related to stage. ❖Founded the discipline of cognitive development ❖Emphasized children’s active involvement in their development ❖Attempted to explain; not just describe development ❖Influenced research in other areas of development (social, emotional)
93
Challenges of Piaget's work
Due to the limited technology available to Piaget, the limited # of children he observed, and a limited understanding of culture, Piaget underestimated children’s cognitive abilities ❖Piaget indicated all children go through sequential stages – but is development sequential and something all children go through uniformly? For example - many cognitive changes in children are gradual and continuous rather than abrupt and stage-like Various aspects of children’s cognition change unevenly ❖Culturally biased methods (focused on Western-educated samples)
94
Lev Vygotsky's Theory of Development
Lev Vygotsky’s Sociocultural Theory of Development Cognitive development is inseparable from social and cultural contexts Cognitive development occurs the support of more knowledgeable others in a child’s world – MKOs May vary from culture to culture
95
Vygotsky’s Sociocultural Theory of Development includes:
- zone of proximal development - scaffolding - importance of language
96
Zone of proximal development
difference between what a child can do alone/independently or with assistance - part of vygotsky's sociocultural theory of development
97
Scaffolding
- part of vygotsky's sociocultural theory of development The support provided initially to facilitate a child’s learning of a skill may be a lot – verbal, hand over hand, demonstration, imitation - It's a teaching strategy As the child develops the skill, the scaffolding gets less until the child can do the skill independently
98
Importance of language
Language plays an important role in cognitive development Inner speech or thought is used for mental reasoning and regulate own behaviour External speech is used to converse with others – helping a child to learn - part of vygotsky's theory
99
What are the contributions of Vygotsky
His Sociocultural Theory of Development Vygotsky’s work has had a significant effect on aspects such as education ❖Cooperative/collaborative learning Educational implications Active collaboration with family Active collaboration with peers
100
habituation
decrease in responding with repeated exposure to an event - like walking the same route every day
101
dishabituation
if stimulus suddenly changes -> increase in responsiveness with presentation of new stimulus - like walking to school and there's a new bright car in a driveway
102
Social and emotional development
Social and emotional development is a lifelong process (from birth to death) that in significantly important to helping people across the lifespan learn to understand, express, and manage their emotions, and to form and maintain healthy relationships with others.
103
Social cognition
thinking people have and demonstrate about the thoughts, feelings, motives and behaviours of themselves and other people.
104
Self awareness/ self concept
one’s perceptions of one’s unique attributes or traits - a combination of physical and psychological attributes
105
Development of the self
begins at birth significant development during toddler's development
106
Rouge test
- Most 12-month-olds touch the mark on the mirror - Most 15-month-olds touch the mark on their face; indicating they recognize the infant in the mirror as themselves
107
Social and Emotional Development - Infants
The ‘social smile’ appears around 4 weeks – happiness ❖ Stranger anxiety starts at 8-9 months, peaks at 12-15 months ❖ Infants experience diverse emotions – sometimes all at once ❖ Through the first year of life infants begin to refine their emotional expression ❖ Infants develop interest in other people very quickly after birth ❖ An infant’s temperament is a key factor in emotional regulation but also social relationships - basic emotional style that appears early in development and is largely genetic in origin ❖ Development of the Self-Awareness- the ability to recognize one’s individuality.
108
Attatchment
- part of social emotional development Attachment describes a close reciprocal emotional relationship between two people; people we feel closest to across the lifespan. ❖Attachment is not a trait or skill. ❖It is the quality of the inter-dependent, bidirectional relationship of individuals, across the lifespan. ❖Attachment - emotional security is a strong need maintained by the trust in the availability and responsiveness of key individuals in our lives during times of distress. This sense of security also extends to relationships across the life span. With development, this security shifts in emphasis of need.
109
Role of fathers
With parental leaves being shared by parents, there is an increasing # of fathers are becoming attachment figure
110
Attachment styles
Attachment Styles were not created by Bowly in his original conceptualization of attachment. ❖They were created by Mary Ainsworth. Type A Secure Type B Insecure avoidant Type C Insecure anxious ambivalent ❖ They have been seen as the problem with attachment – not culturally relevant. ❖Solomon and George conceptualized the 4th style of parenting Type D Disorganised (not Ainsworth’s work
111
Fourth style of parenting
Solomon and George conceptualized the 4th style of parenting Type D Disorganised (not Ainsworth’s work)
112
The Problem with assessing attachment security
The strange situation developed by Mary Ainsworth involved: Laboratory test of eight episodes Simulates caregiver–infant interactions in everyday life Infant’s behaviour is recorded Attachment style can be determined ❖IMPORTANT - that the strange situation has inherent problems. Research indicates the strange situation is not an appropriate measure of attachment and not culturally relevant
113
Social and emotional development in childhood:
Generally preschool and school age children are much better able to regulate their emotions and understand the emotions of others. ❖Differences in children’s social and emotional development can be influenced by culture, trust in relationships, and biological factors (temperament). ❖Friendships often become important in childhood - Continued development of the Self- Awareness ❖Self esteem and self concept
114
Important factors of childhood social and emotional development
secure attachment parenting style cultural differences
115
Adolescence
Transition between childhood and adulthood ❖ Spans 12 – 25 years of age World Health Organization – increased age of adolescence due to the fact that the brain (prefrontal cortex) is not fully developed until 25 ❖ Puberty ❖ Primary and secondary sex traits ❖ Estrogens and androgens are present in both sexes, though the ratios are different Estrogens higher in women, androgens higher in men
116
Hary Harlow
monkeys taken away from mother clung to cloth pads rather than wire mother regardless of which one had food
117
memory
collection of several systems that store information in different forms for different amounts of time
118
Atkinson-Shiffrin Model
describes memory: three memories stores: sensory, short-term and long term memory jk
119
Control processes
shift processes from one memory store to another (represented by arrows in figure 7.1)
120
attention
selects with information will be passed onto Short term memory
121
encoding
how we narrow info we receive in STM - process of storing infor in the LTM system
122
retrieval
brings infor from LTM back into STM - happens when you become aware of long term memories - not perfect
123
Iconic memory
visual form of sensory memory (0.5-1sec)
124
Echoic memory
auditory form of sensory memory (5-10sec)
125
Sensory memory
memory store that accurately holds perceptual info for a brief amount of time the shortest memory ex. access codes - includes iconic memory and echoic memory
126
What are the two peak times of brain development
infancy and adolescence
127
STM
short term memory store - limited capacity and duration (30 seconds) Very brief, 5-20 seconds * STM in adults is usually 7 pieces of information * Rehearsal extends the duration of STM information * Can extend our STM span by using chunking information * Chunking is the organization of a large body of information into smaller, more meaningful groups
128
chunking
organizing smaller units of information into larger more meaningful units (textbook definition) breaking larger pieces of information into chunks (Pitt's definition)
129
LTM
long term memory holds memories for extended periods of time, if not permanentaly - no capacity limitation that we know of May last decades or a lifetime (perma-store) * Long-term memory errors tend to be semantic (meaning- related) whereas short-term memory errors tend to be acoustic
130
TOT
Tip of tongue phenomenon - when a word is on the tip of your tongue - we're able to retrieve similar sounding words or words that start with that same letter, but can't retrieve the word you want
131
serial position affect
we remember only first few and last few (like of a list of numbers) but not so much the middle ones
132
proactive interference
process in which the first information is learned, but leaves less room for later learned info/new info
133
retroactive interference
most recently learned info overshadows some older memories you've not yet made into long-term memory

Working memory model
- an active short term memory system - Baddely, 1992 often thought of as a workspace within the mind that is used to carry out operations, store information, and make decisions on a moment-by-moment basis this includes the central excecutive = phenological loop, episodic buffer and visuospacial skechpad
135
Central excecutive
decides which working memory store is most important at a given time Ex. when driving and have to remember number on the radio that they called - choose btw ponological loop, episodic buffer and visuospacial sketchpad
136
Phonological loop
storage component of working memory that relies on rehearsal and stores infor as sounds, auditory code like when you say the same number over and over again in your head
137
rehearsal
repeating information until you do not need to remember it anymore
138
word length effect
ppl remember more one syllable words than 4 or 5 syllable words
139
visuospacial sketchpad
storage component of working memory that maintains visual images and spatial layouts in a visuospatial code
140
feature binding
combining visual features into a single unit
141
episodic buffer
storage component of working memory that combines the images and sounds from other two components into a coherent, story-like episode
142
declarative memories
- aka explicit memory - branch of long term memory - explicit memories that we are consciously aware of and that can be verbalized: including facts about the world and our own personal experiences Includes memories that are conscious or intentionally remembered * Divided into two subparts: 1. Episodic memory - stores memories of personally experienced events 2. Semantic memory - stores facts and information
143
non-declarative memories
- aka implicit memory actions or behaviours that you can remember or perform without awareness a subsystem of long term memory Includes memories that are unconscious or automatic, and aren’t intentionally remembered * Divided into two subparts: 1. Procedural: memory - how to do things, such as motor skills, habits – brushing teeth, singing a familiar song 2. Priming: an individual's exposure to stimuli influences their subsequent response to stimulus without being aware of the connection – simple classical conditioned responses PSYC1000 W 25 Dr. G. Pitt 22
144
Schema
- part of PIaget's theory of cognitive development - like files in brain: when you learn something new it gets put in a file - and may have a pre-existing file and can build on this ex. like learning to drive standard after automatic (Nazli)
145
episodic memories
declarative memories that seem to be organized around episodes and are recalled from first person ex. like recalling episodes of your life like shoulder dislocation
146
semantic memories
declarative memories that include facts about the world - can be active at the same time as episodic memory
147
Procedural memories
branch of non-declarative memory learned through patterns of muscle movements ex. How to walk, tie shoes, drive car ex. is classical conditioning
148
Long term potential
LTP demonstrates there is increase in connective and transmission of nerve signals btw nerves that fire together - like Hebbs law
149
consolidation
process of converting short term to long term memories "Use it or loose it" - happens in hippocampus
150
amnesia
profound loss of at least one form of memory
151
anterograde amnesia
inability to form new memories for evens occurring after a brain injury - inability to consolidate (STM to LTM) - ex. H. M.
152
Who was george sperling?
Sperling flashed a group of letters for 1/20 of a second. * People could recall only half of the letters * When he signaled to recall a particular row immediately after the letters disappeared with a specific tone, people could do so with near-perfect accuracynumbers
153
reconsolidation
hippocampus functions to update, strengthen or modify existing long term memories - like during SLGs
154
cross-cortical storage
phenomenon where long-term declarative memories are distributed throughout cortex of brain, rather than being localized at one region
155
retrograde amnesia
memory for events preceding trauma or injury is lost ex. forgetting everything before an accident like in Gordon Korman's book, Restart
156
157
elaborate rehearsal
prolonging exposure to information by thinking about its meaning and elaborating on it - like in Ashlyn's SLGs
158
LOP
Levels of processing our ability to recall information is most directly related to how information was initially processed - can be shallow or deep
159
Shallow processing
encoding more superficial aspects of a stimulus, like sound or spelling of word (flash cards when you don't know the meaning just memorized the words)
160
Deep processing
related to encoding information on items meaning or function - like in SLGs
161
self-reference effect
when you think of information in terms of how it relates to you, or how useful it is to you - helps us remember later like me trying to relate to all these terms bro LOL
162
Latent learning
Refers to learning that is not directly observable learning that is not immediately expressed by a response until the organism is reinforced for doing so (like Mickey not doing "down" command until he is offered a treat, even though he knows how , or mice not running a maze unless there's cheese at the other end or me not spitting facts until I have an exam and need to do so) Tolman & Honzik proposed that humans (as well as other animals) display latent learning
163
S-O-R theory
stimulus-organism-response theory early view of cognitive model each person or organism will think about or interpret a situation in a slightly different way ex. Erin being offended by a joke, while I find it funny
164
Observational learning
changes in behaviour and knowledge that result from watching others ex. watching people present and read slides and do a goood job (what did they do that worked well) Not based on behaviourism – or conditioning * Don’t have to engage in trial and error to learn something new
165
Four processes involved in observational learning
part of social theory of learning by bandura (latent learing) 1. attention to the act or behavior 2. memory for it 3. ability to reproduce it 4. motivation to do so
166
Imitation
recreating someone's motor behaviour or expression, often to accomplish a specific goal Role of mirror neurons – active during observational learning * Become activated when an animal observes or performs an action can be bad: violence, swearing can be good: studying, manners
167
stimulus generalization
process in which a response that originally occured for a specific stimulus also occurs for different, though similar, stimuli ex: dogs salivate to other noises that sound like a bell (amount was less, but still)
168
extinction of a stimulus
reduction of the conditioned response when a conditionned and unconditionned stimulus no longer occur together ex. if sound of bell or clicking is played and food no longer follows --> salivation will occur less and less until not at all (extinct)
169
acquisition
initial phase of learning in which a response is established/aquired
170
spontaneous recovery
reoccurrence of a previously extinct conditioned response, typically after some time has passed since extinction
171
conditioned emotional responses
are also classical conditioning emotional and physiological responses that develop to a specific object or situation ex: conditioning little Albert to fear
172
conditioned taste aversions
the acquired dislike or disgust for a food or drink because it was paired with illness part of classical conditioning es. Ronan not liking ice cream for the longest time, since once he ate too much and got sick, or me and my goat roti
173
preparedness
a biological predisposition to rapidly learn a response to a particular class of stimuli
174
latent inhibition
frequent experience with a stimulus before it is paired with an unconditionned stimulus, makes it less likely that conditioned taste aversions will occur after a single episode of illness ex. eat same sandwich everyday and get sick once (we are less likely to avert from sandwich)
175
operant conditioning
type of learning in which behaviour is influenced by consequences associated w behaviourism - A type of learning in which behaviour is strengthened if followed by reinforcement or diminished if followed by punishment - involves voluntary actions, unlike classical conditioning, which is automatic (reflex) Change in behaviour created through reward or punishment The organism “gets something” because of its response (food, avoids punishment)
176
contingency
consequence depends on an action ex. getting a good grade is contingent upon studying effectively
177
reinforcement
process where an event or reward that follows a response increases likelihood of response happening again
178
law of effect
rewarded behaviour is likely to recur. Edward Thorndike idea that responses followed by satisfaction (such as studying and achieving a good grade) will occur in same situation, whereas those that are not followed by satisfaction become less likely (sitting next to kat)
179
reinforcer
stimulus that is contingent upon a response and that increases the probability of that response occuring again ex. food appear after pressing button -> more likely to press that button
180
punishment
process that decreases the future probability of a response ex. timeouts, having parents called when I broke a pencil
181
positive reinforcement
strengthening of behaviour after potential reinforcers such as praise, money, or nourishment ex. laughing at profs jokes increases likelihood of them telling jokes
182
negative reinforcement
strengthening of behaviour causes it to remove or diminish a stimulus ex. taking an aspirin to remove a headache putting in earlplugs when Mara was being loud to remove the sound Includes avoidance learning and escape learning
183
avoidance learning
specific type of negative reinforcement that removes the possibility that the stimulus will occur ex. leaving early to prevent running into traffic wearing equipment to prevent injury
184
escape learning
type of negative reinforcement where response moves a stimulus that is already present (ex. covering ears to escape loud music)
185
Positive punishment
process in which behaviour decreases in frequency cause it was followed by particular, usually unpleasant experience ex. spanking, or squirting a cat positive just means that a stimulus is added
186
Shaping
reinforcing successive approximations of a specific operant response - done in step by step process until desired response is learned
187
chaining
linking together 2 or more shaped behaviours in to a more complex action or sequence of actions ex. toilet training or like how they train animals to act in movies
188
ABA
applied behaviour analysis involves using close observation, prompting, and reinforcement to learn behaviours, way of applying operant conditioning
189
primary reinforcers
reinforcing stimuli that satisfy an individual's biological needs to survive basic motivational needs ex. food, water, shelter
190
secondary reinforcers
stimuli that aqcuire their reinforcing effects only after we learn they have value ex. money, "likes" on insta
191
discriminative stimulus
a cue or event that indicates that a response, if made will be reinforced Like: before we pour a coffee, checking if light is on, or checking parents mood before asking a favour
192
discrimination
when an organism learns to respond to one original discriminatory stimulus, but not two (like not a new one that may be similar) ex. pigeon responding to 1000Hz but not 2000Hz
193
Generalization of operant response
operant response occurs in response to a new stimulus that is similar to other stimulus
194
schedules of reinforcement
rules that determine when reinforcement is available reinforcements may be available at highly predictable times
195
continuous reinforcement
every response made results in reinforcement ex. putting money in a vending machine - we always get a snack
196
partial (intermittent) reinforcement
only a certain number of responses are rewarded, or a certain amount of time must pass before reinforcement is available ex. calling sharon and she only picks up sometimes
197
4 Types of partial reinforcement schedules
1. fixed-ratio schedule 2. variable ratio schedule 3. fixed interval schedule 4. variable interval schedule
198
Fixed interval schedule
reinforces the first response occurring after a set amount of time passes - like studying every time there's a test but not so much in between tests
199
Variable ratio schedule
Type of partial reinforcement schedule number of responses required to receive reinforcements varies according to an average Like playing Tims roll up the rim: 1/6 chance these depend on number of responses
200
fixed ratio schedule
type of partial reinforcement reinforcement is delivered after specific number of responses have been completed ex. press lever 10 times before receiving food (every 10 times)
201
variable interval schedule
type of partial reinforcement first response is reinforced after a variable amount of time ex. watching a meteor shower or pop quizzes that arise unexpectedly - gotta constantly be looking or studying outcomes based on how often you study or engage in behaviour
202
Partial reinforcement effect
phenomenon in which organisms have been conditionned under partial reinforcement resist extinction longer than those conditionned under continuous reinforcement ex. superstitions and me wearing the same shirt to hockey cause I may score a goal
203
recognition
identifying a stimulus of information when it is presented to you ex. mc test or police line-up
204
recall
retrieving information when asked but without that information being present during the retrieval process ex. short answer question or describing the criminal's appearance
205
retrieval cues
helped when there are hints = like pictures at the beginning of MCB short answer questions
206
encoding specificity principle
retrieval is most effective when the conditions at the time of encoding and retrieval are the same (ex. chewing gum when studying and chewing when remembering)
207
context dependent memory
idea that retrieval is more effective when it takes place in the same physical setting as encoding --> as characteristics of environment likely serve as retrieval cues Ex. like me practicing mon discours on the miller small gym stage and yeah
208
state-dependent memory
retrieval is more effective when your internal state matches the state you were in during encoding
209
mood-dependent memory
people remember better if their mood at retrieval matches their mood during encoding
210
weapon focus
tendency to focus on a weapon at the expense of peripheral information, including the identity of person holding weapon
211
flashbulb memory
an extremely vivid and detailed memory about an event and the conditions surrounding how one learned about the event ex. the dislocation or discovering yeah...
212
forgetting curve
shows that most forgetting occurs right away, and the rate of forgetting slows to the point where one eventually doesn't seem to forget at all (i think that's when there's like perioding reflection/recollection in between)
213
mneumonic
technique intended to improve memory for specific information
214
method of loci
mneumonic that connects words to be remembered to locations along a familiar path ex. relating first letter of word to location on path
215
acronyms
pronounceable words whose letters represent the initials of important phrase or set of items ex. MADD
216
first letter technique
GPNDS uses the first letters of a set of items to spell out words that form a sequence
217
Dual coding
when information is stored in more than one form ex. verbal description and image (leads to deeper processing)
218
Desireable difficulties
techniques that make studying slower and more effortful, but result in better remembering (and understanding) like going over the MCB processes till remember
219
testing effect
taking practice tests can improve exam performance, even without additional studying
220
cognitive offloading
use of an action or device to reduce cognitive demands imposed by a given task
221
schemas
organized clusters of memories that constitute a person's knowledge or beliefs about events, objects and ideas like files when we encounter similar events, these schemas become active
222
Constructive memory
process by which we first recall a generalized schema and then add in specific details
223
infantile amnesia
you do not have any personal or autobiographical memories from before your 3rd birthday
224
false memory
remembering events that did not occur, or incorrectly recalling details of an event
225
misinformation effect
when information occurring after an event becomes part of the memory for that event
226
source memory
the memory for how or where information was initially acquired ex. remembering when a prof taught a concept or where you heard a fact
227
imagination inflation
increased confidence in a false memory of an event following repeated imagination of the event ex. "Happier" song and ft
228
guided imagery
techniques used by some clinicians (and some police investigators) to help people recover details of events they are unable to remember
229
DRM procedure
participants study a list of highly related words called semantic associates (means associated by meaning) and then the word most obvious is missing (critical lure) but a large portion remember (intrusion)
230
critical lure
the missing word from DRM procedure that a large portion remember
231
intrusion
false memory sneaking into real memory (like the critical lure)
232
recovered memory
memory of a traumatic event that is suddenly recovered after blocking the memory of that event for a long period of time
233
controversy of recovered memory
validity of recovered memories
234
Behaviour Psychology
Behavioral psychology is the study of “external” behavior * Behaviour is objective and observable * Behaviour is the response of an organism to stimuli * Behaviour and learning theorists emphasize experience and learning as the primary forces that shape human behaviour * Behaviour can be controlled by consequences - type of reinforcement following the behaviour * Classical Conditioning and Operant Conditioning PSYC1000 W25 Dr. G. Pitt 3
235
Thorndike's experiment
cat in a puzzle box - has to pull string to open door to get food (it does this faster and faster) operant conditionint - law of effect
236
B.F. Skinner's work w operant conditionning
Pioneer in his work with operant conditioning * Was influenced by Thorndike’s Law of Effect With his studies, Skinner designed an operant chamber, or Skinner box. * To help his subjects/animals learn different behaviors, he started with shaping, which gradually guides the animal to the desired behavior Skinner used shaping as a technique to teach rats a complicated task * The rat was rewarded for each response that is closer to the final desired behavior – press lever for food. * Process of reinforcing successive approximations of a specific operant response
237
What did skinner develop?
Skinner developed two types of reinforcement: 1. Positive Reinforcement: * strengthens a response by presenting a desirable stimuli 2. Negative Reinforcement: * strengthens a response by reducing or removing something undesirable or unpleasant
238
Why do we seek reinforcement?
Nucleus accumbens is active during processing of rewards, both natural and artificial * Dopamine is released during operant conditioning when behavior is rewarded Dopamine-releasing neurons in nucleus accumbens and other areas maintain record of rewarding behaviors
239
Two types of cognitive learning:
1. Latent learning 2. Observational Learning
240
Tolman & Honzik research
on LATENT LEARNING Their research involved three groups of rats run through the maze 10 times. * The first group was rewarded every time they found the route out. * The second group was rewarded only after the 10th time. * The third group was never rewarded Results: * The second group quickly performed as well as the first group after receiving a reward. * The second group was learning but only demonstrated their knowledge when they received reinforcement worthy of quickly running through the maze. * Rats could learn a maze without reinforcement * Rats would not show their learning until they received reinforcement * Rats developed cognitive maps that were only used once there was a reinforcer Tolman & Honzik’s Maze Trials challenged behaviourism * Thinking plays a role in some forms of learning
241
Social learning theory
Bandura Development / behaviour learned through modeling, observation, imitation and self-efficacy in learning as seen in the work of Albert Bandura. * Observational learning and BoBo the Clown - occurs when a child observes another person perform an action and then tries to imitate it. * Bandura proposed the concept of reciprocal determinism of the environment on the child and vice versa
242
Bandura's experiment
Social theory of learning Children exposed to the aggressive model were more likely to act in physically aggressive ways than those who were not exposed to the aggressive model. (Boys averaged 38.2 with 12.7 for girls) * Children are more influenced by same- sex models. * Results showed that boys exhibited more aggression when exposed to aggressive male models than boys exposed to aggressive female models.
243
memory
- A system that encodes, stores and retrieves information. * Can be defined as ‘the retention of information’ * Not static and can change over time - Memories can be surprisingly good in some cases and surprisingly poor in others (memory paradox)
244
What is the neural basis for change in the vrain during memory storage
Synaptic Changes * Neural basis for change in the brain during memory storage is in the synapses. * Memories begin as impulses travelling through the brain circuits, leaving a semi-permanent trace. * The more a memory is utilized, the more potential strength that neuron has, called long-term potentiation.
245
Two parts of brain involved in memory
Hippocampus and Amygdala both in the Midbrain. * Hippocampus helps recall the events themselves * Involved in a process called consolidation. * Information in the working memory is gradually changed over to long term memories. * Memories are also date/time stamped by the hippocampus * Amygdala helps recall emotions associated with events * The amygdala plays a role in strengthening memories that have strong emotional connections. PSYC1000 W 25 Dr. G. Pitt 10
246
Hormones and memory
Strong memories fueled by emotion. * Emotional arousal = release epinephrine and norepinephrine * Cortisol = in excess interferes with memory. * Estrogen = improves working memory.
247
at what age do we start to see memory decline?
65
248
Multistore model
Multistore Model (Atkinson, & Shiffrin, 1968): * The flow of information in thinking * Information flows through three processing units. 1. Sensory store: holds raw sensory information from senses 2. Short-term store (STS): stimuli retained for several seconds 3. Long-term store (LTS): examined information stored for future us
249
Interference with STM
We lose information in STM due to two different processes 1. Decay – fades over time 2. Interference – loss of information due to competition with other information retroactive interference and proactive interference
250
likely location for working memory
the frontal cortex.
251
Two limitations of working memory
limited capacity and short duration
252
event memory
long-term memory for events * Children from individualistic cultures tend to recall events from their own perspective and retrieve information related to their personal goals. * Children from collectivist cultures encode, retain, and retrieve more social aspects of events.
253
Three steps in the process of memory
- Encoding * Storage * Retrieval
254
3 types of encoding
1. Semantic Encoding * encoding of meaning * including meaning of words 2. Acoustic Encoding * encoding of sound * especially sound of words 3. Visual Encoding * encoding of picture images
255
Ebbinghaus's Curve of Forgetting
Used himself as the subject. * He memorized a long list of nonsense syllables which he chose because they had no meaning to him. * He measured his retention of the list of syllables at certain intervals. * Forgetting was most rapid at first - his retention of only 58 percent after 20 minutes and 44 percent after one hour. * Then the rate of forgetting tapered off * 34 percent after one day, 25 percent after six days, and 21 percent after 31 days. * The forgetting curve shows that most forgetting occurs right away, and that the rate of forgetting slows to the point where one does not seem to forget at all.
256
Causes of forgetting
Encoding Failure * Material not put into LTM. Decay * Unused memories disappear with time. Consolidation Failure * Disruption in consolidation. Interference * Old (proactive) or new (retroactive) information interferes with learning or recall.
257
