Context-aware experience sampling reveals the scale of variation in affective experience

Area of Science:

• Psychology
• Affective Science
• Psychophysiology

Background:

• Traditional emotion research seeks consistent physiological patterns for specific emotions like anger or fear.
• Existing studies reveal more physiological variation than expected within emotion categories.
• This challenges the notion of discrete, universally consistent physiological signatures for emotions.

Purpose of the Study:

• To explore the structure within the observed variation of physiological activity during emotional experiences.
• To investigate individual differences and commonalities in physiological responses and associated affect.
• To test a constructionist view of emotion, emphasizing variable instances tied to context.

Main Methods:

• A novel, physiologically-triggered experience sampling method was employed.
• Peripheral physiological activity and self-reported affect were recorded during spontaneous cardiac changes unrelated to movement.
• Unsupervised clustering analyses were used to identify recurring patterns within and across participants.

Main Results:

• Significant variability was found in the number and nature of recurring physiological patterns within individuals.
• The affect ratings and emotion labels associated with these patterns also varied.
• Broad, shared patterns of physiological activity were identified across participants.

Conclusions:

• Findings support a constructionist perspective on emotion.
• Emotion categories are conceptualized as populations of variable instances.
• These instances are linked to situation-specific needs and adaptive responses.
