This publication includes two studies. The first experiment involved the prediction of mixed schema learning in a reproduction task. Subjects (Ss) learned to distinguish among the schemata without knowledge of resuts. A best fitting equation describing performance as a function of number of reproduction trials accurately predicted learning with new Ss and patterns randomly sampled from a different population (schema). These findings are related to previous research involving generalization of results in a single schema reproduction task. In the second study, a transfer design was used to assess the effects of incidental training and knowledge of results (KR) on mixed schema learning in a reproduction task. The results indicated that schema learning is no faster with KR than without KR and that schemata can be learned when Ss merely attend to the stimuli. The relevance of schema theory to concept formation and other cognitive processes is discussed. (Author)
