Summary

This study found that heart rate increases during intuition tasks. This suggests physiological changes accompany covert cognitive activity, supporting dual-process models of intuition.

Area of Science:

  • Cognitive Neuroscience
  • Psychophysiology

Background:

  • Intuition is a complex cognitive process.
  • Understanding the physiological underpinnings of intuition is crucial for cognitive science.

Purpose of the Study:

  • To investigate heart rate changes during a pure intuition task.
  • To determine if covert cognitive activity, like intuition, elicits physiological responses.

Main Methods:

  • Two experiments with 12 subjects each were conducted.
  • Subjects guessed a target image from four options presented sequentially.
  • Heart rate was recorded during the task, with 20 trials per subject.

Main Results:

  • A statistically significant increase in heart rate was observed when subjects encountered target images compared to non-target images.

  • Replication experiment confirmed the initial findings.

    • Conclusions:

    • Heart rate changes are associated with covert cognitive activities, including intuition.
    • Findings support models of intuition as a dual, partially independent information processing system.
