The tie that binds? Coherence among emotion experience, behavior, and physiology

Area of Science:

• Psychology
• Affective Science
• Psychophysiology

Background:

• Emotion theories often propose coherence across experiential, behavioral, and physiological response systems.
• Empirical evidence supporting this emotion coherence postulate remains surprisingly limited.
• Understanding response system interplay is crucial for advancing emotion theories.

Purpose of the Study:

• To investigate within-individual associations between experiential, facial behavioral, and peripheral physiological responses during emotional episodes.
• To determine if emotion intensity moderates the coherence between these multiple response systems.
• To provide empirical data on the response system coherence during induced amusement and sadness.

Main Methods:

• Second-by-second measurement of experiential, facial behavioral, and peripheral physiological responses.
• Utilized a film paradigm to elicit specific emotional states (amusement and sadness).
• Statistical analysis to assess within-individual associations and moderation by emotion intensity.

Main Results:

• Strong associations were observed between emotional experience and facial behavior.
• Peripheral physiological responses showed only modest associations with both experience and behavior.
• The intensity of amusement experience predicted greater coherence between behavior and physiology, but sadness intensity did not.

Conclusions:

• Findings challenge the universal assumption of strong coherence across all emotion response systems.
• Response system coherence may be state- and intensity-dependent, particularly for physiological measures.
• Highlights the complex and nuanced nature of emotional responding.
