100
Which gender showed bilateral results for prefrontal cortex activity?
Females
100
What does the amygdala do?
Fear-related emotional response
100
What stage of Piagets cognitive development are adolescence in?
Formal Operations
100
True or False: Was there an adequate group size for this study?
False
200
What was the correlation between age and activity in the amygdala?
None
200
What is the pre-frontal cortex responsible for?
Executive functions: mediating conflicting thoughts making choices predicting future events inhibition
200
What is does the formal operation stage allow you to do?
Abstract thought Reason logically
200
Why is the flaw of only using fear/happiness unavoidable?
These emotions elicit a strong, identifiable response
300
True or False: Because this study shows that there is a positive correlation between age and prefrontal cortex activity, activity in other structures, decreases.
False
300
What were the two questions the experiment was studying?
1. When adolescents view fearful facial expressions, will brain activity in the prefrontal cortex be positively correlated to age? and 2.Would activity within the amygdala be negatively correlated to age?
300
As the prefrontal cortex matures, what kind of faces can adolescents identify?
Fearful
300
What were the problems with data collection?
Data did not account for behavioral data such as level of attention and emotional responses.
400
What were the results for when participants were shown happy faces?
Age-related correlations were not present
400
What was the age range of participants?
8-15 years old

What is one of the main contributors of the resulting differences between boys and girls?
Puberty
400
Which type of study would have been more effective?
Longitudinal Study
500
This study has confirmed the idea that the brain does not reach it's full volume until around what age?
Early 20s.
500
Which part of the brain is the amygdala in?
Limbic sysyem
500
The MRI study in lecture showed increase in which type of matter?

500
What other part of the brain was emphasized in class, as continuously developing during development?
Cerebellum
