Behavioral research on negotiation in recent years has been dominated by th
e decision-making research paradigm, which accords a relatively narrow role
to emotions. Decision-making researchers have considered emotions primaril
y in terms of how an individual's positive or negative affect impacts, and
usually impedes, his or her information processing. Drawing on recent advan
ces in psychology and other fields, we propose an alternative perspective t
hat highlights more social and more functional aspects of emotion in negoti
ation. We conceptualize emotions as interpersonal communication systems tha
t help individuals navigate the basic problems that arise in dyad and group
relations. Emotions are evoked by these specific relational problems and o
ne person's emotional expression impacts other persons, often with the cons
equence of resolving the relational problem. From this social functional pe
rspective, we draw insights concerning: (a) the influence of specific emoti
ons upon negotiation-related cognition and behavior; (b) the transitions be
tween qualitatively different phases within negotiations; and (c) the ways
in which negotiations are shaped by contextual variables such as culture an
d communication media.
