Casey Flashcards
What was the aim of the Casey et al (2011) study?
To assess whether delay of gratification in childhood predicts impulse and self-control abilities in adulthood at the behavioural and neural level
The study also examined sensitivity to social cues.
What type of research method was used in the study?
Quasi-experiment
The independent variable is naturally occurring and not manipulated.
What is the independent variable (IV) in the study?
Whether the participant was a high or low delayer
What was the dependent variable (DV) in Experiment 1?
Participants’ performance on a go/no-go task in terms of reaction times and accuracy
What additional data was examined in Experiment 2?
Brain scan (imaging) results from the fMRI
How many children participated in the original delay of gratification task?
562 children aged 4 years old
How many participants were left by the end of the study?
117 participants
What was the gender breakdown of participants in Experiment 1?
23 males and 36 females
How many participants were classified as high delayers?
32 participants (12 males and 20 females)
How many participants were classified as low delayers?
27 participants (11 males and 16 females)
How many participants from Experiment 1 consented to brain scanning in Experiment 2?
27 participants
What was the gender breakdown of participants in Experiment 2?
13 males and 14 females
How many high delayers participated in Experiment 2?
15 high delayers (5 males and 10 females)
How many low delayers participated in Experiment 2?
11 low delayers (7 males and 4 females)
What type of tasks were participants subjected to during the experiment?
Delay of gratification tasks and facial expression tasks
What were the two main types of tasks used in the study?
Hot task and cool task
What is the significance of the ‘go/no-go’ task in the study?
It measures impulse control and reaction times
What type of design was used in the experiments?
2×2 factorial design
What were the two main variables in the factorial design?
Sex (Male, Female) and Accuracy
True or False: All participants in the study were male.
False
