Training attentional filtering, not memory storage, improved decision-making performance on the Iowa Gambling Task (IGT). This suggests selective attention is key for enhancing decision-making efficiency.

Area of Science:

  • Cognitive Neuroscience
  • Decision Science

Background:

  • Decision-making is crucial for daily functioning but its relationship with cognitive abilities like executive control and memory remains unclear.
  • The Iowa Gambling Task (IGT) is a standard tool for assessing decision-making strategies in simulated real-life scenarios.

Purpose of the Study:

  • To investigate whether training attentional filtering or memory storage influences decision-making performance.
  • To determine the impact of specific cognitive training on the Iowa Gambling Task (IGT).

Main Methods:

  • 29 healthy young adults underwent five days of either working memory (WM) storage training or attentional filtering training.
  • Participants' IGT scores were assessed after each training session.
  • Training involved distinct computerized tasks targeting either memory recall or filtering distractors.

Main Results:

  • Both training groups showed improvement in their respective trained cognitive tasks.
  • Only the attentional filtering group demonstrated a significant increase in money gained on the IGT over time.
  • Decision-making efficiency, as measured by the IGT, was enhanced by filter training but not by memory training.

Conclusions:

  • Training attentional filtering skills positively impacts decision-making, suggesting a stronger role for selective attention than working memory storage.
  • Selective attention may underlie the previously observed links between working memory and Iowa Gambling Task performance.
  • Enhancing selective attention could be a viable strategy for improving decision-making efficiency.
