Casey

Question 1

What is the aim of casey’s study?

Answer 1

Wether delay of gratification in childhood predicts impulse control activities when participants were older.

Question 2

What was the the study looking at in casey?

Answer 2

Impulse control on both a behavioural level and a neural level

Question 3

What did the researchers also want to find in casey?

Answer 3

Sensitivity to alluring or social cues

Question 4

What was the samples for experiment 1 in casey?

Answer 4

•59 participants
•Mixture of high(32) and low(27) delayers
•Male and female

Question 5

What was the sample in casey for experiment 2?

Answer 5

•26 participants of the 59 from exp 1

Question 6

What was the procedure in exp 1?

Answer 6

•Provided with laptops at home
•Asked to complete the nimstim trials (flashed faces for 500milliseconds)
•2 versions of the go-nogo task:
Cold-Neutral faces and one image the target(female) and ignore male.
Hot-Happy fearful faces/ mix of genders
press go for happy and and no go for fearful

Question 7

What is the DV for exp 1?

Answer 7

Accuracy was measured and reaction times

Question 8

What is The procedure for exp 2?

Answer 8

•Only the hot task was done while brain activity measured with the fmri.
•Participants responses on the 5 button respond pad to the NO-GO trials of happy/fearful faces

Question 9

What were the findings of exp 1 in casey’s study?

Answer 9

•High n low delayers we’re not significantly different in reaction time and for accuracy on “go” trials
• low delayers made significantly more false alarms on the “no-go” trials than high delayers especially in the hot tasks with happy faces.

Question 10

What were the findings in exp 2 in casey’s study?

Answer 10

•Low delayers had reduced brain activity in there inferior frontal gyrus compared to high delayers in the “no-go” task
•Low delayers had increased activity in there ventral striatum on no-go trails compared to high delayers

Question 11

What are three conclusions from casey’s study?

Answer 11

1Sensitivity to environmental hot cues plays a significant role in a individual’s ability to suppress actions towards alluring cues
2)Those with difficulties at a young age have difficulties at an older age
3)Resistance to temptation is a relatively stable individual difference.
