Effect of degree of cue separation and stimulus encoding method on cue sample size and learning rate

Response mode research shows that participants under a judgment response mode demonstrate more compensatory processing than participants under a choice mode. Research on affect and choice reveals that positive-affect participants display more noncompensatory examination of information than negative-affect participants. In the present study, participants viewed a film clip to induce positive or negative affect and made judgments or choices for a series of candidates for a university professor's position. Results indicate a powerful effect for response mode across all dependent variables whereby judgment participants took more time, looked at more information, and showed less search variability than choice participants. The influence of affect, however, was undetectable, and several hypotheses are advanced to account for this finding. Acknowledgements This thesis is dedicated to my late brother Erik.
