Individuals with greater working memory capacity demonstrate enhanced syllogistic reasoning skills. Performance aligns with predictions from both mental model theory and probability heuristics models, suggesting these cognitive factors influence logical deduction.

Area of Science:

  • Cognitive Psychology
  • Human Cognition

Background:

  • Working memory capacity is crucial for complex cognitive tasks.
  • Syllogistic reasoning involves evaluating logical arguments.

Purpose of the Study:

  • To investigate the relationship between working memory span and syllogistic reasoning.
  • To compare empirical performance with predictions from mental model theory and probability heuristics model.

Main Methods:

  • Two experiments were conducted to assess syllogistic reasoning.
  • Participants' working memory spans were measured.
  • Performance was analyzed against theoretical predictions.

Main Results:

  • A positive correlation was found between working memory capacity and reasoning performance.

  • Higher working memory capacity led to responses more consistent with both theoretical models.
  • The observed relationship between working memory and performance supported both theories.

    • Conclusions:

    • Working memory capacity significantly impacts syllogistic reasoning ability.
    • Findings support the explanatory power of mental model theory and probability heuristics model in understanding reasoning processes.
