Cognitions about bodily purity attenuate stress perception.

Area of Science:

• Psychology
• Cognitive Science
• Social Psychology

Background:

• Physical purity is often associated with a 'clean slate' phenomenon.
• Cognitions about bodily cleanliness may influence psychological states like stress perception.

Purpose of the Study:

• To investigate if cognitions about bodily cleanliness modulate stress perception.
• To explore the mechanisms underlying the relationship between cleanliness cognitions and stress.
• To examine the role of ease-of-retrieval and the number of recalled events in stress perception.

Main Methods:

• Participants visualized themselves in either a clean or dirty state.
• Self-reported frequency of past stress-related situations was recorded.
• Mediation analysis and direct manipulation of recalled event quantity were employed across three studies with large sample sizes (N > 500 per study).

Main Results:

• Cognitions of cleanliness reliably reduced perceived stress.
• The effect was not solely due to cognitive engagement in stress recall.
• Ease-of-retrieval of past stressful events correlated negatively with perceived stress.
• Recalling fewer events increased perceived stress frequency, contrasting with the ease-of-retrieval finding.

Conclusions:

• Bodily cleanliness cognitions offer a novel pathway for stress reduction.
• The findings contribute to understanding purity-related 'clean slate' effects.
• Results may inform interventions for stress management and provide insights into washing rituals in obsessive-compulsive disorder (OCD).
