The sustained attention to response task (SART) effectively measures impulsive responding, not sustained attention. This task is sensitive to impulsivity, as shown in two studies using global-local stimuli.

Area of Science:

  • Cognitive Psychology
  • Neuroscience

Background:

  • The sustained attention to response task (SART) is commonly used to assess sustained attention.
  • Its efficacy in measuring impulsive responding versus sustained attention requires further investigation.

Purpose of the Study:

  • To determine if the SART is a more accurate measure of impulsive responding than sustained attention.
  • To evaluate the SART's sensitivity to impulsivity under varying task conditions.

Main Methods:

  • Two experiments were conducted using target detection tasks with global-local letter stimuli.
  • Participants utilized either a standard response format (responding to targets) or the SART (withholding response to targets).

Main Results:

  • SART performance demonstrated rapid changes over time, unlike the stable performance in the standard format.

  • The SART was susceptible to global-local interference effects, consistent with findings in highly impulsive individuals.

    • Conclusions:

    • The SART is a sensitive indicator of impulsive responding.
    • The findings suggest the SART is a more effective tool for assessing impulsivity than sustained attention.
