Pathological gamblers (PGs) exhibit more "chasing losses" and poorer decision-making than non-pathological gamblers (NPGs). This study quantifies within-session gambling behavior to identify vulnerabilities to gambling pathology.

Area of Science:

  • Psychology
  • Behavioral Science
  • Neuroscience

Background:

  • Pathological gambling (PG) is characterized by chasing losses.
  • Understanding episodic chasing behavior is crucial for identifying gambling pathology.

Purpose of the Study:

  • To quantitatively compare episodic chasing between pathological gamblers (PGs) and non-pathological gamblers (NPGs).
  • To investigate the relationship between sensation seeking and decision-making strategies in gambling behavior.

Main Methods:

  • Compared 61 PGs and 39 NPGs using the Iowa Gambling Task (IGT) and Zuckerman Sensation Seeking Scale (SSS).
  • Analyzed quantitative differences in within-session decision-making patterns, specifically episodic chasing.

Main Results:

Related Experiment Videos

  • PGs demonstrated significantly more chasing behavior and poorer decision-making than NPGs.
  • These differences were particularly pronounced in males.
  • Lower sensation seeking was associated with random play, not advantageous or disadvantageous play.

Conclusions:

  • Quantifiable within-session gambling behavior, like chasing, can help detect vulnerabilities to pathological gambling.
  • Decision-making strategies and sensation seeking are relevant factors in understanding gambling pathology.
