Affective Influences on Partner Choice: Role of Mood in Social Decisions



Joseph P. Forgas

University of New South Wales

Sydney, New South Wales, Australia





Does mood influence our information search and decision strategies when choosing a partner? In

Experiment 1 (N = 60), sad Ss preferred rewarding to competent partners and remembered infor-

mation supporting that choice better. In Experiment 2 (N = 96), mood effects on information

selectivity, decision speed, and processing strategy in partner choices were found. In Experiment 3

(N = 42), a computerized stimulus presentation revealed mood-induced differences in the latency,

self-exposure, and eventual recall of interpersonal information. These results are interpreted as

evidence for mood-induced selectivity in information search and decision strategies when making

realistic partner choices. The implications of the findings for research on interpersonal relations

and for contemporary affect-cognition theories are considered.









Feelings often influence the quality of our social judgments, 1990). Such decisions—like most social judgments—usually
