title: Differentiated selves help only when identification is strong and tasks are complex.
abstract: Whereas differentiation is overestimated - it more often hurts than helps group performance - identification is underestimated. A more viable perspective sees identification and cooperative motivation as the sine qua non of group functioning, with differentiation helping in a relatively narrow set of cognitively complex tasks that require creativity and deep and deliberate information processing by individual members.
