- Casey's Study into Delayed Gratification(2011)
- CONCLUDE- The ability to resist temptation differs between individuals and is associated with varying levels of activity within the inferior frontal gyrus and ventral striatum. These individual differences do persist with age but can also be influenced by contextual cues.
- AIM- to test whether delay gratification in childhood predicts impulse self controls abilities in adulthood.
- EXPERIMENT 1- In experiment 1 there was a gratification task which aimed to show that children(low delayers) would as adults show less impulse control in supressing responses to hot cues relative to the cool cues.
- EXPERIMENT 2- participants were put into an fMRI scanner whilst completing the hot version of the go- no go task. An electronic response pad was used to record their answers.
- METHOD - the study was a quasi experimental design as it was naturally occurring whether you were a high or low delayer.
- EXPERIMENT 1- In experiment 1 there was a gratification task which aimed to show that children(low delayers) would as adults show less impulse control in supressing responses to hot cues relative to the cool cues.
- METHOD - the study was a quasi experimental design as it was naturally occurring whether you were a high or low delayer.
- RESULTS- Experiment 1 both groups were highly accurate and gave correct responses to both the go and no go versions of the task. Low delayers were slightly more likely to respond mistakenly compared to the high delayers in the hot version of the task.
- RESULTS- Experiment 2- No significant difference between reaction time within the two groups however the low delayers accuracy was less as they made more mistakes in no go trials at a rate of 14.5%.
- The inferior frontal gyrus was critical in with holding responses for low delayers compared to the high delayers in the no go trails.
- The ventral striatum shown higher levels of reward for the low delayers compared to the high delayers as there was more activity.
