In the area of social psychology, sociologists have drawn more frequen
tly from psychologists than the reverse. This is in part because socio
logists more often assess the degree to which status characteristics,
social relationships, and structural contexts influence individuals' t
houghts, feelings, and behaviors, while psychologists more often expli
cate the mechanisms through which such social factors affect individua
ls. I illustrate these differences by discussing points of parallel th
eoretical development between the two disciplines, substantive divisio
ns of labor, and selected topics of mutual inquiry. Although sociologi
sts benefit substantially from psychologists' work, sociologists could
offer their counterparts more pointed demonstrations that sociologica
l mechanisms are crucial for explaining key psychological phenomena an
d that structural contexts constrain individuals' behaviors in ways of
ten overlooked by psychologists.
