Casey et al. recap

Casey et al.'s study aimed to find out if ___ ___ was a stable throughout a person's life?

What was the IV in experiment 1?

• Hot or Cold task

• Low or high delayer

• Neutral or happy faces

The dependent variable in experiment one was...

• Low or high delayer

• Reaction time and accuracy on go/nogo tasks

• Reaction time and accuracy on hot tasks only

• Brain activity in certain areas during go/nogo tasks

The dependent variable in experiment two was...

• Low or high delayer

• Reaction time and accuracy on go/nogo tasks

• Reaction time and accuracy on hot tasks only

• Brain activity in certain areas during go/nogo tasks

How did the experimenters place participants in the categories of high or low delayers?

• Random assignment

• Result of the self-report questionnaires

• The marshmallow/ cookie test

The study began with 562 Ps, but only 59 took part in experiment 1,and 27 in experiment 2. This is known as... (use the correct term)

Experiment 1: which is NOT a result?

• Low delayers performed less well in 'hot' tasks

• There was no difference in reaction times between the two groups

• High delayers performed better in cold tasks than low delayers

• High delayers showed better impulse control overall

Experiment 2: which is NOT a result?

• In hot tasks, low delayers had more activity in their ventral striatum

• In hot tasks, low delayers had less activity in their inferior frontal gyrus

• In hot tasks, high delayers had more activity in their ventral striatum

• Low delayers showed more false alarms, but not significantly

Participants received ___ in their 20s and 30s to see if they still identified as high or low delayers

The ___ task was a go/nogo task using neutral faces
