Positive affectivity

Positive affectivity (PA) is a human characteristic that describes how much people experience positive affects (sensations, emotions, sentiments); and as a consequence how they interact with others and with their surroundings.[1]

People with high positive affectivity are typically enthusiastic, energetic, confident, active, and alert. Research has linked positive affectivity with an increase in longevity, better sleep, and a decrease in stress hormones.[2][3] People with a high positive affectivity have healthier coping styles, more positive self-qualities, and are more goal oriented.[4][3] Positive affectivity also promotes an open-minded attitude, sociability, and helpfulness.[1]

Those having low levels of positive affectivity (and high levels of negative affectivity) are characterized by sadness, lethargy, distress, and un-pleasurable engagement (see negative affectivity). Low levels of positive affect are correlated with social anxiety and depression, due to decreased levels of dopamine.[5]
