Topic 2 Child Psychology

?
In early brain development what happens to synaptic production?
It goes into overdrive
1 of 25
In adolescent brain development what reaches its peak therefore changing synaptic production?
Grey Matter
2 of 25
In adolescent brain development what elimination allows the brain to become more efficient?
Elimination of connections that aren't used enough
3 of 25
In terms of impact on risk taking what system of the brain responsible for processing emotions matures faster than the prefrontal cortex?
Limbic system
4 of 25
What part of the brain is highly sensitive towards rewards and does this mature fast?
Ventral striatum, in some cases yes
5 of 25
What does this maturation lead to?
Encourages adolescents to do more adult activities that have rewards at the end
6 of 25
In Barkley-Levenson's key research how many adult participants were they and what was their age range?
19 and 25-30
7 of 25
In Barkley-Levenson's key research how many adolescent participants were there and what were their age ranges?
22 and 13-17
8 of 25
What type of experiment was the key research?
Quasi
9 of 25
What type of data was collected?
Neural and behavioural
10 of 25
What were participants told in terms of the $20 they were given to use as playing money?
They could either win another $20 or loose their money
11 of 25
How was neural data collected and what part of the brain were they very interested in?
MRI scans and ventral striatum
12 of 25
How was behavioural data recorded?
Acceptance or rejection to each trial recorded
13 of 25
In results of neural activation what was shown about activation of VS in adolescents compared to adults?
More activation as expected value increased in adolescents
14 of 25
What was one behavioural difference between the two groups?
When no risk was involved both groups made similar decisions
15 of 25
Give one conclusion from this study
Adolescents place a greater value on rewards
16 of 25
In application of key research give one existing strategy used to reduce risk taking
The graduated driver licensing scheme
17 of 25
In this scheme there are one or more probationary periods. Name 2 restrictions these periods contain
Limits on number & age of passengers and restrictions on alcohol
18 of 25
What does research into neurological change help us understand? (Usefulness of research)
Reasons for risk taking behaviour
19 of 25
What does research into neurological change help us identify and what do these identifications do?
Identify strategies to help teach adolescents about damage of risk taking behaviour
20 of 25
How can this research be argued in the Nature side of the debate?
Some neurological changes and processes are innate and sensitivity to rewards is likely to be part of natural process of neural development
21 of 25
How can this research be argued in the Nurture side of the debate?
Stimulation from environment plays huge role in development
22 of 25
How can this research be seen from a Free Will perspective?
Risk taking involves reasoning and decision making by adolescents and behavioural choices aren't determined
23 of 25
How can the application of this research be seen as a holistic strategy?
Involves changing context that places limitations on behaviour& delays getting full license allowing maturation
24 of 25
How can this research be seen to be scientific?
Able to control environment so no extraneous variables and produced empirical data and highly replicable
