Unpacking outcome dependency: Differentiating effects of dependency and outcome desirability on the processing of goal-relevant information

Outcome dependency has been shown to have a substantial impact on impression formation. Perhaps because the outcome dependency variable is a composite variable (including variation in amount of dependency, desirability of outcome, or both), many different effects have been described by researchers. The current research unpacks the outcome dependency variable by separately examining effects of dependency (when outcome desirability is held constant) and effects of outcome desirability (when amount of dependency is held constant). Using research methods adapted from those used in the attitudes domain, variation in the amount of dependency on a target person influenced the level of objective processing of target information (when outcomes were not substantial, Experiment 1), but variation in the desirability of the outcomes influenced biases in the processing of information (when dependency was relatively high, Experiment 2). Furthermore, personal motivation mediated effects of desirable outcomes on positive biases in processing (Experiment 3).
