The information used to choose the larger of two objects from memory was investigated in two experiments that compared the effects of a number of variables on the performance of subjects who either were instructed to use imagery in the comparison task or were not so instructed. Subjects instructed to use imagery could perform the task more quickly if they prepared themselves with an image of one of the objects at its normal size, rather than with an image that was abnormally big or small, or no image at all. Such subjects were also subject to substantial selective interference when asked to simultaneously maintain irrelevant images of digits. In contrast, when subjects were not specifically instructed to use imagery to reach their decisions, an initial image at normal size did not produce significantly faster decisions than no image, or a large or small image congruent with the correct decision. The selective interference created by simultaneously imaging digits was reduced for subjects not told to base their size comparisons on imagery. The difficulty of the size discrimination did not interact significantly with any other variable. The results suggest that subjects, unless specifically instructed to use imagery, can compare the size of objects in memory using information more abstract than visual imagery. 相似文献

A series of four experiments is reported in which reaction times for naming line drawings were analyzed as a function of the similarity of the print superimposed on the drawings to the printed label for the drawing. This effect was studied as a function of grade level (ages 6, 8, and 11 years) and, hence, reading experience. The studies were designed to determine more precisely the characteristics of the stage of visual feature analysis of word identification and to examine response competition factors in this interference task. Results indicated that a combination of end letters and word shape was important for word identification and that response articulation was a significant distinct interference component in this task. 相似文献

Four mentally retarded adolescents who showed little or no expressive or receptive language were given a series of tests to determine if they could respond to meaningful nonlinguistic sounds. The tests required the subjects to respond to sounds on the basis of meaning by classifying the sounds according to the objects which produced them, i.e., the sound sources. The results show that the subject could not classify the sounds on the basis of their source although they could discriminate between them. These results are in contrast to the near perfect classification by another retarded subject who lacked speech due to a motor disorder but, nevertheless, showed good understanding of language. The finding that some nonverbal children have difficulty in responding to the meaning of nonlinguistic sounds suggests the possibility that the failure of these children to develop language may have been due to an agnosia not unlike that found in adult stroke patients. 相似文献

A theory of intelligence is couched in stimulus-response terms, bridging the gap between S-R and cognitive psychology. The chief theoretical concepts are span ability (a capacity notion), response string (sequentially cued responses), and complexity of stimulus control (task complexity). Span is equated with the ability to respond appropriately when several cues are conjunctively relevant for correct performance (complex stimulus control). So defined, span is consistently and broadly related to many aspects of intelligent behavior. 相似文献

Sex-role stereotyping in the linguistic structure of Holland's Self-Directed Search (SDS) was examined. A revised SDS was constructed involving the removal of all masculine-toned terminology from the items and test-taking instructions, as well as the affixing of the letters M/F and F/M to all occupational titles and terms commonly perceived as gender specific. Subjects were 266 lower division female students at a large state university; 133 subjects completed the standard SDS and 133 completed the revised form. Following SDS assessment, subjects rated their inventory with respect to perceived sexual equality. Comparison variables included: daydreams, occupations' scores, summary codes, and subsequent occupational choices. Occupational choices at each stage of the assessment process were classified as nontraditional or traditional choices for women. Results indicated that across all indices derived from the standard and revised versions of the SDS, there were no significant differences in these subjects' performance. The subjects did perceive the two inventories differently, with subjects completing the standard SDS viewing it as slightly less equitable. 相似文献

Generalization effects of social skills training in chronic schizophrenics: An experimental analysis
Social skills training was administered to three (one male and two female) chronic schizophrenic patients in a Partial Hospitalization Service. Treatment consisted of instructions. feedback and modeling, and was administered in 25. 26 and 31 sessions, respectively, for the three patients. Target behaviors were identified for each patient based on his/her responses to role-played interactions involving male and female partners in situations requiring commendatory or hostile assertion. Five to seven target behaviors were selected for each subject and were treated sequentially in a multiple baseline format. Skills training was highly successful for the two female patients but was only partially effective for the male patient. Two forms of generalization measures were included, indicating that the effects of training generalized from trained to untrained, and trained to novel role-played interactions. Follow-up assessments for the two female patients indicated that most of the effects persisted over 8–10-week post-treatment periods. 相似文献
