“…Across the life span, those who have difficulty deciphering subtle cues to the thoughts, feelings, and intentions of those around them are prone to a range of psychological disorders (Rosenthal, Hall, DiMatteo, Rogers, & Archer, 1979;Russell, Stokes, Jones, Czogalik, & Rohleder, 1993). Impairments and systematic biases in social judgment are theorized to play a particularly important role in the development and maintenance of depression (Coyne, 1976;Lewinsohn, 1974); this speculation has received considerable empirical support (e.g., Feinberg, Rifkin, Schaffer, & Walker, 1986;Giannini, Folts, Melemis, Giannini, & Loiselle, 1995;Lane & DePaulo, 1999;Zuroff & Colussy, 1986). The present work represents an attempt to consider the role of sadness, at both state and trait levels, in the ability to draw valid inferences about others on the basis of thin slices of behavior.…”
