The present study investigated the efficiency of various existing measures, mainly psychological tests, for predicting job performance of mentally retarded workers in a sheltered occupational shop. Twenty-two production-related jobs and one nonproduction-related job were analyzed with the Position Analysis Questionnaire resulting in two job attribute clusters. Correlations between 19 predictor variables and 5 criterion variables, which consisted of supervisor ratings of job performance, were then calculated separately for subjects performing preferred jobs in each attribute group. The results indicated that, contrary to past research, existing measures are predictive of performance on some but not all jobs in a sheltered workshop. 相似文献

Three experiments are reported in which digits spoken at different rates were recalled and monitored. In Experiment I, digits to be recalled were embedded in varying levels of noise. In Experiment II noise was presented only during the inter-digit intervals, either to the same or to the opposite ear as the digits. In Experiment III Ss monitored these sequences for a specified digit and reported its successor. Stimulus rate and signal-to-noise ratio affected perceptual processing time, as evidenced by the frequency and relative proportion of item and order errors. These stimulus factors induce listening strategies that influence the shape of the serial position curve and that persist after stimulus conditions are changed. The data are consistent with a two-stage processing model for the temporal course of speech perception and the nature of listening strategies. 相似文献

Studies are reported among West African populations on the relationship between preferred mode of organization of categorizable material and use of organization in recall. Various child and adult groups differed in the types of organization they imposed on the material in a sorting task, with those exposed to school and modernizing influences showing a preference for taxonomic organization. All subjects, however, used their own form of organization to order their subsequent recall of the material, supporting the idea that organizing processes in recall are universal. 相似文献

Two experiments investigated how much time Ss take to verify a sentence with respect to a set of subject-verb-object (SVO) propositions they had learned. Three triplets of SVOs provided differing degrees of equivocation, including (1) unique SVOs, (2) a V with 3 SOs, and (3) an SV with 3 Os. A general class of models was proposed regarding the representation of prepositional trees in memory and an algorithm by which a probe tree might be verified against a set of trees in memory. In Expt I, verification times were least for Condition (1), slower and equal for Conditions (2) and (3). In Expt II, a fourth condition, an SO with 3 Vs, produced verification times as slow as those in Condition (3). Of several models considered, the closest-fitting one assumed parallel search processes proceeding simultaneously from S, V, and O positions of the probe, scanning through memory trees structered according to the HAM (Human Associative Memory) theory of Anderson and Bower. 相似文献
