Strategy adaptivity relies on explicit awareness of changes, not working memory capacity. Understanding strategy choice mechanisms requires further investigation beyond current models.

Area of Science:

  • Cognitive Psychology
  • Decision Making
  • Behavioral Science

Background:

  • Strategy choice is fundamental to cognitive processes.
  • Existing models inadequately explain adaptivity to changing environments.
  • The roles of awareness and working memory in strategy adaptation require clarification.

Purpose of the Study:

  • To investigate the influence of explicit awareness and working memory on strategy adaptivity.
  • To examine how individual differences in awareness and working memory capacity affect strategy adjustments.
  • To test the predictive power of awareness and working memory in strategy choice models.

Main Methods:

  • Three experiments were conducted to assess strategy adaptivity.
  • Correlational analyses examined relationships between strategy adaptivity, awareness, and working memory capacity.

  • Working memory load was manipulated using a dual-task procedure in one experiment.

    • Main Results:

    • Individual differences in strategy adaptivity correlated with awareness of base-rate changes.
    • Awareness at the time of change, not post-change awareness, predicted strategy adaptivity.
    • Working memory capacity and load did not appear to influence strategy adaptivity across experiments.

    Conclusions:

    • Explicit awareness, particularly at the moment of environmental change, is crucial for strategy adaptivity.
    • Working memory capacity does not seem to be a significant factor in strategy adaptation.
    • Current models of strategy choice may need revision to incorporate the role of awareness.
