When we want to know what others are feeling, we look to the face for clues
. However, individual differences matter: Some faces are more expressive th
an others. Do both emotion experience and dispositional expressivity predic
t emotion expression? Based on an analysis of display rules, the authors hy
pothesized that expressivity would moderate the relation between experience
and expression for negative, but not for positive, emotion. Study 1 examin
ed the relation between habitual emotion experience and peer-rated expressi
ve behavior and showed the predicted moderator effect for negative emotion:
Experience was related to expression only for dispositionally high-express
ivity participants, not for low-expressivity participants. For positive emo
tion, however, experience was related to expression for both groups. Study
2 replicated these findings using momentary emotion experience and objectiv
ely coded expressive behavior during films that elicited amusement and sadn
ess. Results are interpreted in terms of low expressivity individuals' prop
ensity to dynamically regulate negative emotion-expressive behavior.
