Casey et al. (2011) neural correlates of delay of gratification: the go/no-go task and results

  • 3 things to know
  • Component 02

Overview

Recall questions on the go/no-go task used by Casey et al., its cool and hot versions and target reversal, the behavioural findings, and the prefrontal cortex and ventral striatum findings for low and high delayers.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What does a participant have to do in a go/no-go task?

    Model answer

    They must press a button as quickly as possible whenever a go stimulus appears but withhold the response when the no-go stimulus appears.

  2. 2

    Why are there far more go trials than no-go trials?

    Model answer

    So that responding becomes an automatic habit, which makes it genuinely difficult to inhibit the response when a no-go trial arrives.

  3. 3

    What stimuli were used in the cool version of the task?

    Model answer

    Faces that had to be sorted by sex, so the go and no-go cues carried no emotional content.

  4. 4

    What made the hot version of the task hot?

    Model answer

    It used happy and fearful facial expressions, with the happy face acting as a socially rewarding and therefore tempting cue.

  5. 5

    Why was the target reversed across the two runs?

    Model answer

    So that each expression acted as both a go and a no-go cue, ruling out the possibility that one type of face was simply easier to respond to.

  6. 6

    What was found on the cool task?

    Model answer

    High and low delayers performed equally well, with no significant difference in the number of errors.
