Where are the unique predictions?

Comments on the article by J. P. Forgas (see record 2002-10335-001) on psychological theories linking affect, cognition, and behavior. N. Schwarz addresses 2 questions: What drives the effects of task complexity, and what drives affective influences on requests? He contends that Forgas's research strategy focuses on common rather than distinct predictions and neglects the identification of conditions that allow for a diagnosis of the processes underlying interpersonal behavior.
