Q

What is the aim of the study

A

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

Q

What was the fMRI used to examine

A

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

Q

Conclusion

A

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
