Two experiments are reported in which a cognitive (attributional) model of achievement motivation is applied to two achievement-related behaviors, persistence and selection of intermediate-risk tasks. Results of Experiment I indicated that S's perceived effort expenditure was related to persistence for high achievers. In Experiment II, high achievers made more intermediate risks than low achievers. There were no significant differences within achievement groups across public and private attributional conditions. Results were discussed in terms of establishing environmental conditions conducive to the performance of achievement related behaviors. (Author)
