Question 1

What is the area

Answer 1

Biological

Question 2

What is the aim of the study

Answer 2

To assess whether delay of gratification in childhood predicts impulse control abilities and sensitivity to alluring or social cues (happy faces) at the behavioural and neural level when ppts were in their 40s adults

Question 3

What was the research method

Answer 3

Quasi/ natural experiment

Question 4

What was the IV

Answer 4

Whether the ppt was a high delayed it a low delayed naturally

Question 5

What was the dv

Answer 5

Behaviour
Performance in the impulse control task measured by reaction times and accuracy in experiment 1
Neural activity
Performance in impulse control task measures by reaction times and accuracy
And results of Fmri scans in experiment 2

Question 6

Why was it a longitudinal study

Answer 6

Longitudinal study as some of the original ppts from the age of 4 until they were in their 40s

Question 7

What was the experimental design

Answer 7

A repeated measures design

Question 8

How many ppts as 4 year old

Answer 8

562 ppts

Question 9

How many ppts in the end

Answer 9

59 ppts

Question 10

What was the fMRI used to examine

Answer 10

FMRI was used to examine activity in the ventral striatum and inferior frontal gyrus to see if it correlated with delay of gratification

Question 11

Conclusion

Answer 11

Resistance to temptation is a relatively stable characteristic of an individual over time
The capacity to resist temptation (cognitive control) can be strongly influenced by contextual factors
Ability to resist temptation is supported by neural networks in the brain
Low delayers have lowered activity in the Underwood frontal gyrus and increased activity in the ventral striatum
