The literature on self-predictions and self-efficacy suggests that, with age, accuracy is stressed at the expense of speed in performing a psychomotor task. To investigate the relationship between self-rated performance, actual performance, and task preferences as a function of age, 175 females, ranging in age from 17 to 72 years, were placed into one of seven age groups: 17-24 years, 25-32 years, 33-40 years, 41-48 years, 49-56 years, 57-64 years, 65-72 years, and were administered a complex reaction time task. Upon completion of the task participants were administered a semantic differential on which they evaluated themselves and the task. Results indicated that at all age levels individuals were inaccurate in predicting their own performance. Further, individuals tended to evaluate the task on the basis of how well they thought they performed. These findings support the assumptions of self-efficacy theory, rather than the hypothesis that self-predictions increase with advanced age. (Author/BL)
