Casey Flashcards
what is the aim of this study
to build on previous research to assess whether delay gratification in childhood predicts impluse control abilities and sensitivitey to alluring or social cues
what is the background
Eigsti 2006 showed performance on a delay of gratification task in childhood predicted the efficiency with which the same individuals performed on a cognitive control task
what method was used
quasi experiment
what is the independent variable
whether the participant was a high delayer or a low delayer
what is the dependant variable
performance on the impulse control task (in terms of reaction times and accuracy) in experiment 1 and the performance on the impulse control task and imaging results on the fmri
why was this study a repeated measures design
some p’s completed self control scales in their 20s and 30s and those participants in experiment 1 did both the hot and cold tasks in their 40’s
why was this a longitudinal design
4 till 40s
completed a self control questionaire when they were in their 20s and 30s and they did both hot and cold tasks in their 40’s
what was the sample
562 4 year old pupils from stanford bing nursery school completed a delay of gratificaiton test
how many participants agreed to do the functional neuroimaging part of the study
27
what does delayed gratification mean
describes the process that the subject undergoes when the subject resists temptation of an immediate reward in preferance for a later reward
what is a high delayer
someone who can wait
what is a low delayer
could not wait and took the immediate reward
what is a hot que
emotional response
what is a cool que
no response
what was experiment 1
on preprogramed laptops sent to the p’s house they had to complete go/no go tasks with hot or cool ques.
what was the cool task in experiment 1
clicking when a target (a specific gender) was presented
what was the hot task in experiment 1
identical to the cool task but instead of the gender being the stimuli it was happy or fearful faces
what was experiment 2
the same as experiment 1 but in a fmri scanner
which group of people made the most errors on the happy no go task
most errors in the low delayers
did the ventral striatum have more activity in the high delayers or low delayers
low delayers
did the inferior frontal gyrus have more activity in the high delayers or low delayers
high delayers
give one conclusion
sensitivity to environmental ques (hot)play a significant role in an individuals ability to supress actions towards alluring ques
what ethical concerns are there in this study
protection from harm if the p’s become distressed with their scores
what similarities are there between sperry and casey
quasi experiment
repeated measures design
opportunity sample
what differences are there between sperry and casey
S- snapshot design
C- longitudinal design
