Pathological gamblers exhibit impaired cognitive control, performing significantly slower and less accurately on the reverse Stroop Color-Word Test. This suggests neurobiological underpinnings for decision-making deficits in gambling disorder.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Pathological gambling is a prevalent disorder with severe consequences.
  • Neurobiological research aims to understand decision-making impairments in pathological gamblers.
  • Inability to inhibit irrelevant information is a potential cognitive deficit.

Purpose of the Study:

  • To investigate neurocognitive deficits in pathological gambling using the Stroop Color-Word Test.
  • To assess interference control in medication-free pathological gamblers.
  • To compare performance between pathological gamblers and healthy controls.

Main Methods:

  • Administered the reverse Stroop Color-Word Test to medication-free pathological gamblers (n=62) and age-matched controls (n=83).

Related Experiment Videos

  • The reverse Stroop task assesses the ability to inhibit interference by requiring subjects to read word meaning, not ink color.
  • Collected data on reaction time and accuracy.

    • Main Results:

    • Pathological gamblers were significantly slower and less accurate on the reverse Stroop task compared to controls.
    • Pathological gamblers showed slower reaction times in the neutral condition than the incongruent condition, a novel finding.
    • Performance impairment on the Stroop task was evident in this sample.

    Conclusions:

    • Cognitive control, specifically interference inhibition, is impaired in pathological gamblers.
    • These findings support neurobiological theories of decision-making deficits in gambling disorder.
    • The reverse Stroop task is a valuable tool for assessing cognitive impairment in psychiatric populations.
