Affect intensity, a measure of emotional experience, is not linked to physiological arousal. However, higher affect intensity correlates with less accurate perception of one's own cardiac arousal.

Area of Science:

  • Psychology
  • Psychophysiology
  • Affective Science

Background:

  • Affect intensity describes the typical strength of emotional experience.
  • Cardiac arousal refers to physiological responses of the heart.
  • Understanding the link between emotional experience and physiological self-awareness is crucial.

Purpose of the Study:

  • To investigate the relationship between affect intensity and basal, evoked, and perceived cardiac arousal.
  • To examine how accurately individuals perceive their own physiological arousal.
  • To explore gender differences in affect intensity and cardiac arousal perception.

Main Methods:

  • Administered the Affect Intensity Measure (AIM) to assess affect intensity.
  • Evoked cardiac arousal through physical exercise and mental arithmetic tasks.

  • Measured perceived cardiac arousal using a heartbeat discrimination task.
  • Conducted three distinct experimental studies.

    • Main Results:

    • Women, on average, reported higher affect intensity.
    • Affect intensity showed no significant relationship with basal or evoked cardiac arousal.
    • Affect intensity was negatively correlated with perceived cardiac arousal across all studies.
    • Individuals with higher affect intensity were less accurate in perceiving their heart rate.

    Conclusions:

    • Affect intensity is independent of objective physiological arousal levels.
    • Affect intensity is inversely related to the accuracy of self-perceived cardiac arousal.
    • Findings suggest that emotional experience intensity influences interoceptive accuracy, potentially explained by an expanded arousal-regulation model.
