To examine same of the relationships between causal attribution processes and affective reactions to success and failure outcome, 112 male and 60 female college students were administered a booklet of materials to elicit affective reactions to success or failure. The matelials consisted of descriptions of eight different achievement situations. Each desription consisted of an outcome and one of eight causal attributions for the outcome. Dependent measures for success consisted of eleven rating scales of success-related affect, and measures for failure consisted of nine rating scales of failure-related affect. For each affect, subjects were instructed to indicate on a 4-point rating scale how strongly they would feel that affection in each of the achievement situations. The method of dual scaling was applied to the affective reactions. Results revealed that there were two different types of achievement-related affects, i.e., outcome dependent and attribution dependent. The implication of the findings for the relation between attribution processes and affect are discussed.
