This study was designed to determine if observing a similar or dissimilar model who makes varying self-efficacy statements influences an observer's efficacy expectations and, in turn, muscular endurance performance. Females (N = 150) were randomly assigned to groups in a 2 × 4 × 3 (model similarity by model talk by trials) factorial design or to a no-model control group. Model similarity was manipulated by having subjects view a female described as a nonathlete (similar) or a male described as a varsity track athlete (dissimilar). The four levels of model talk included: a positive self-talk model who performed and made positive self-efficacy statements, a negative self-talk model who made negative self-efficacy statements, an irrelevant-talk model who made statements unrelated to self-efficacy, and a no-talk model who remained silent throughout the performance. Self-efficacy measures were assessed in addition to performance on three trials of a muscular endurance task. Results revealed that similar model subjects extended their legs significantly longer than dissimilar model and control subjects. Moreover, the similar-positive-talk and similar-no-talk groups performed significantly better than the dissimilar-positive-talk, dissimilar-negative talk, dissimilar-no-talk, and the no-model control groups. Subject self-efficacy, however, was not found to be the major mediating variable affecting these performance changes.
