Tested the notion that arousal affects the retrieval strategy of pigeonholing by decreasing the separation between risky and cautious criteria. 75 undergraduate Ss heard short meaningful stories accompanied by either No, Medium, or High Noise and were asked to recall the characters' names. Common names were better recalled than rare names in each noise condition. A decision theory analysis shows that, in the No-Noise condition, Ss employed a risky criterion for common names and a cautious criterion for rare names. In the noise conditions, however, Ss employed a similar criterion for recall of both common and rare names, but sensitivity increased for common names. Results are interpreted as supporting the hypothesis that arousal affects the accessibility of information for retrieval. A possible mechanism for arousal's action, and the theoretical implications of these findings are discussed. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
