Effects of task success or failure on causal attributions and person perception.

An actor's outcome on a task (success-failure) was manipulated orthogonally to information that the actor either used or did not use drugs. Casual attributions for success-failure were obtained as well as trait ratings of the actor. Subjects read a case study of an artist who either succeeded or failed in his profession. For half of the subjects, the artist was described as using hard drugs, and no mention of drugs was made for. the other half. It was predicted and confirmed that success-failure interacted with drugs-no drugs in determining attributions of ability. It was also found, as expected, that success was attributed to ability and motivation more than was failure. Further, success tended to be internally attributed to the actor, while failure was externally attributed. The interaction obtained for ability attribution was not obtained for a measure of trying, nor for the trait ratings. The results confirmed Kepka and Brickman's (1971) suggestion that ability and motivation are qualitatively different concepts in naive psychology, but some of their specific conclusions are questioned.
