Abstract

Positive affect has been related to faster cardiovascular recovery from stress. Although the family of positive affective states is diverse, no study examined whether high-approach positive affect (e.g., desire) has a different impact on peripheral physiological processes than more frequently studied low-approach positive affect (e.g., amusement). Building upon prior work on emotions and motivation, we expected that after controlling for arousal and valence, positive affect with higher motivational intensity would facilitate weaker recovery when compared to positive affect with lower motivational intensity. Across two experiments (N = 179 for Study 1, N = 220 for Study 2), we measured cardiovascular, respiratory, and electrodermal responses to positive stimuli that differed in approach intensity. We measured responses during recovery from stress and during reactivity to threat and anger. These studies partially replicated previous findings regarding the soothing function of positive affect (e.g., in respect to diastolic blood pressure recovery and reactivity). However, we found that high-approach and low-approach positive affect produced comparable effects. In summary, these findings suggest that positive valence rather than motivational intensity produces the main soothing effect on peripheral physiology.
