In 14 experiments, subjects had to “point to” surrounding environmental locations (targets) while imagining themselves in a particular spot facing in various directions (orientations). The spatial information was either committed to memory (cognitive maps) or directly presented on each trial in the visual or tactile modality. Reaction times (RT) indicated that orientation shifts were achieved through mental rotation in the visual task, but not in the cognitive map or tactile tasks. Further, in the latter two tasks targets were located most quickly when they were adjacent to or opposite the imagined orientation. Several explanations of this finding were tested. Various aspects of the data suggest that cognitive maps are not strictly holistic, but consist of orientation-specific representations, and—at least in part—of relational propositions specific to object pairs.  相似文献

Children of 8 and 11 years were assessed in two experiments for their sensitivity to textual anomaly. In Experiment 1, subjects read stories containing two target lines, one appropriate and the other anomalous in relation to previously given information. Both age groups read the anomalous line more slowly than the appropriate line, but in a subsequent test of comprehension monitoring, the older group was more likely than the younger group to pick out the anomalous line as not fitting in with the rest of the story. Experiment 2 produced similar results: both 8- and 11-year-old children read an anomalous line more slowly, but 11-year-olds were more likely than 8-year-olds to cite the anomalous line or part of it when questioned about the possible presence of a line that did not fit in with the rest of the story. The results indicate that an age change in comprehension monitoring as indexed by citation or selection of a textual anomaly need not be contingent upon a parallel age change in constructive processing as indexed by modulation of reading rate.  相似文献

Within the context of an identified need for establishing a support group for single custodial fathers, this article discusses a five-session group experience that included such topics as dating, remarriage, homemaking and house maintenance, and the effects of divorce on children.  相似文献

The psychomotor development of 1,406 low socioeconomic infants from Santiago, Chile, was examined. Four groups of infants were assessed: 12, 15, 18 and 21 months of age. Results indicated that as chronological age increased, the number of infants who fell into at-risk or delay categories increased.  相似文献

The role of visual imagery in short-term retention of movement end locations and distances was examined by comparing performances of subjects with extreme scores on the space relations section of the Differential Aptitude Test. Twelve HIGHS and twelve LOWS were tested on reproduction accuracy of six distances and six end locations immediately following presentation a 30-sec rest, a 30 sec imaginal rehearsal condition, and a 30-sec imaginal distraction condition. Initial analysis of the data provided little support for the hypothesis that HIGHS would reproduce criterion locations with more accuracy than LOWS. However, when scores of HIGHS reporting use of an imaginal coding strategy (HIGHS) were compared with LOWS who did not (LOWS), several expected findings were disclosed. HIGHS reproduced end locations with significantly less error in the immediate and imaginal rehearsal conditions, and as expected, accuracy scores for HIGHS and LOWS did not differ for the distance task. The findings suggest that when subjects employ an imaginal coding strategy, visual imagery ability may be an important factor in the retention of location information, but of little functional significance in the recall of distance.  相似文献

The present study expands the typical Barnum effect paradigm by investigating reactions to feedback in a group setting. People initially participated in a group experience (8 per group), and then were given bogus positive or negative feedback (the favorability manipulation) purportedly prepared by either the group leader or another group member (the source status manipulation). The answerability manipulation led participants to believe that they either would or would not have to share their reactions to the feedback with the person who prepared it. Positive feedback was rated as more accurate and accepted more highly than the negative feedback, though no differences in recall of either the positive or negative feedback emerged. Additionally, a pattern of results revealed that the feedback from the group leader generated greater perceived accuracy, acceptance, and recall than did feedback from another group member. Implications for the impact of feedback given by a high status person in group settings are discussed.  相似文献
