  • 3 things to know
  • Component 02

Overview

Recall questions on the background and aim of Casey et al.'s 2011 study of the neural correlates of delay of gratification, hot and cool systems, the combined methods, the original cohort, high and low delayers, and the participants.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What earlier research provided the starting point for this study?

    Model answer

    Preschool delay of gratification experiments in which four-year-olds chose between a small treat straight away and a larger treat if they could wait.

  2. 2

    State the aim of Casey et al.'s study.

    Model answer

    To find out whether the ability to delay gratification in childhood persists into middle age, and to identify the brain regions involved in resisting a tempting cue.

  3. 3

    How does the hot system differ from the cool system?

    Model answer

    The hot system is a fast, emotional, reward-driven system based in limbic structures such as the ventral striatum, while the cool system is a slower cognitive control system based in the prefrontal cortex.

  4. 4

    Which methods were combined in this study?

    Model answer

    A longitudinal quasi-experiment comparing pre-existing groups of high and low delayers, using laboratory go/no-go tasks and functional magnetic resonance imaging.

  5. 5

    Who made up the original cohort?

    Model answer

    562 four-year-olds who were tested on delay of gratification at a university nursery school in the late 1960s and early 1970s.

  6. 6

    How were participants classified as high or low delayers?

    Model answer

    By showing consistent performance on the childhood delay task and on self-control measures taken again when they were in their twenties and thirties.
