Q

Language takes part in what side of the brain

21
Q

Primary motor cortices are responsible for

A

movement of the opposite sides of the body e.g. left hemisphere, right hand

22
Q

Adaptive plasticity

2 parts and what they do

A

Sprouting - occurs from damage or new experience and growth of new neural connections occurs

Re-routing - An undamaged neuron that has lost a connection with an action neuron may seek a new active neuron to connect with

23
Q

Brain development during adolescence

Amygdala
Cerebellum
Corpus Callosum

A

Amygdala - more active here, impacts on the emotional state

Cerebellum - Increase in the number of neurons and synapses. results in unco-ordinated balance and movement

Corpus Callosum - Thickens and allows for more communication between hemispheres

24
Q

Hindbrain structures

A

Cerebellum
Medulla
Pons

25
Midbrain structure
Reticular formation
26
Forebrain structure
Hypothalamus Thalamus Cerebrum
27
Difference between developmental and adaptive plasticity
Developmental plasticity changes in neural connections as a result of interactions with the environment as a consequence of developmental processes whereas adaptive plasticity is the brains ability to compensate for lost functionality due to brain damage as well as in response to interaction with the environment by reorganising its structure.
28
Synaptogenesis
the process of moulding or forming new synapses
29
Broca's Aphasia
Speech is non-fluent, many pauses Consists of very short and simple sentences, mainly verbs and nouns, lacks grammar Difficult writing Left frontal lobe
30
Wernicke's Aphasia
Speech is fluent but nonsense words are used or are mispronounced Difficulty understanding both written and spoken language Left temporal lobe
31
Spatial Neglect
a disorder in which the person affected systematically ignores stimuli on one side of their body. Spatial neglect occurs after brain damage, usually in the posterior region of their right parietal lobe and results in the person ignoring stimuli on their left side.
32
Hereditary factors
genetic material inherited from their parents
33
environmental factors
physical, social and emotional surroundings
34
Development is a combination of
environmental and hereditary factors
35
Interactionalist Approach
The idea that hereditary and environmental factors continually interact to influence developmental change
36
what impact does raising identical twins together have on the development of their characteristics as well as how they are treated
- if raised in the same households with similar experiences, then the same environmental factors would impact - they look the same and are more likely to be treated alike. Friends, teachers and extended family may have difficulties telling them apart or want to treat them fairly and equally - the environmental influences are the same
37
limitation of identical twin studies
in generalising from these findings is due to the selection of adoptive parents. In most cases, the infants were matched with families of similar education and social background (Hay 1985). Therefore, although reared apart, the twins were raised in similar environments
38
Nature/Nurture Intelligence
Hereditary strong influence Families who live together often share the same genes and environment If a family has children whose parents and grandparents all have high intelligence, then it is possible that either their genes or their family environment or the interaction between the two is responsible for their high intellectual activity
39
Nature/Nurture Personality
Common for personality traits to continue into adulthood e.g. Sensitive and emotional children tend to become nervous and withdrawn adults
40
Stages of lifespan and milestones
Infancy - talking, walking, motor skills, social interactions with family, self-recognition, self-identity Childhood - forming friendships, starting school Adolescence - high school, puberty, independence Early Adulthood - getting a job, children, marrigae, peak of physical functioning, sophisticated cognitive functioning, intimacy and independence Middle Adulthood - stable self-identity, stable career, physical declines become noticeable Late Adulthood - health declines, retirement, close ties to family
41
Physical development
Impacts on physical functioning. It is how you physically change over years like learning how to hold a pen, or tie your shoelace
42
Cognitive development
The development of our mental abilities through the course of the lifespan. Our memories, language and problem-solving abilities change throughout our lives
43
Social-emotional development
As you grow older your understanding of social rules and situations changes, you change socially and emotionally. You develop the ability to regulate your emotions. Your emotions are influenced by the environment and society
44
Difference between learning and maturation
The main difference between learning and maturation is that learning is the process of acquiring knowledge, skills, and behaviours, whereas maturation is the process of becoming mature or developed. Thus, maturation is a mental and physical growth, whereas learning is mainly a mental process
45
Inborn reflexes
Automatic responses to specific stimuli, inborn reflexes are initially due to nature (heredity) Eg: being able to sit or stand up on their own as an infant
46
Developmental norms
- They indicate the average age that a certain behaviour or skill will be achieved. They're based on the mean average of a large sample. - Provide feedback on whether the infant is progressing normally in relation to the rest of the population
47
Critical vs Sensitive periods
Critical periods are development times of special sensitivity to certain environmental factors that can shape an individual's capacity for future development whereas sensitive periods are the best or optimal times for psychological development in certain areas, such as learning to speak which allows for the possibility that, given the right circumstances, individuals can still experience psychological development, even if the individual began with deprived conditions
48
Teratogens
Are toxic substances that are capable of harming an unborn child
49
Experience expectant and experience dependent learning
EE - These are situations in which a species-typical experience plays a necessary role in the development organisation of the nervous system ED - Is a form of learning that can occur at any time during an individual's life. It refers to adaptive plasticity, encoding new experiences that occur throughout life, fostering new brain growth and refining existing brain structures
