This work evaluated the prospect that organizational accounts of the retention of list information by monkeys might be an artifact of familiarity with conditional relationships. Seven sophisticated macaques were trained on four five-item lists. Each acquisition selectively excluded one of the internal conditional pairs of the typical four-problem sequence (AB,BC,CD,DE) that defines a five-item serially ordered list. Then, all possible novel pairings and the trained pairs appeared together in a test. After this, the previously omitted pair was trained and animals were retested. On all tasks, initial tests revealed little organization and much intersubject variability of characteristic choice strategies, but subsequent inclusion of all four conditional pairs always yielded organized serial choice. On both the four-problem tests and in a later retention, errors were directly related to interitem distance between the objects paired on test trials. These results helped to specify the conditions required for demonstration of non-human primate analogs of transitivity, and showed that even sophisticated monkeys organize information in retention only if they know all interitem relationships.

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior.  相似文献

Children are immature in face recognition, particularly in face configural decoding. This study examines the developmental difference of face recognition in another mechanism: viewpoint transformation processing. Adults and sixth‐grade children were instructed to match a series of one‐tone black face silhouettes to their corresponding front‐view faces. This task involves sophisticated calculation in pictorial information, precise viewpoint transformation, and most probably a 3‐D face representation. The results showed that although the performances were well above chance level in the recognition of familiar faces, for children, they were at chance level in the recognition of unfamiliar faces. The results indicate that children, at least to the age of about 12 years, are still immature in the processing of face viewpoint transformation compared to adults.  相似文献

Group discussion significantly improves performance on intellective problems. However, most experiments have been conducted in Western cultures. Cross‐cultural psychology suggests that members of Eastern cultures might be less likely to benefit from group discussion. One experiment in Japan suggested that this was not the case, but this experiment suffered from some limitations. To address these limitations, Japanese participants were asked to solve an intellective task four times: individually (pre‐test), in small discussion groups (test), individually again (transfer task, post‐test), and individually after a delay (delayed post‐test). The results revealed a robust improvement during group discussion. Groups in which at least one member had found the correct answer individually agreed on it during the discussion. Moreover, and in contrast with results obtained in Western cultures, most groups with no such member also found the correct answer. The gains obtained during discussion were maintained in the transfer tasks. This result provides further evidence that the improvement of reasoning performance in group discussion is a universal phenomenon, and provides support for the practice of collaborative learning in Japan.  相似文献

Spatial scaling is an integral aspect of many spatial tasks that involve symbol-to-referent correspondences (e.g., map reading, drawing). In this study, we asked 3–6-year-olds and adults to locate objects in a two-dimensional spatial layout using information from a second spatial representation (map). We examined how scaling factor and reference features, such as the shape of the layout or the presence of landmarks, affect performance. Results showed that spatial scaling on this simple task undergoes considerable development, especially between 3 and 5 years of age. Furthermore, the youngest children showed large individual variability and profited from landmark information. Accuracy differed between scaled and un-scaled items, but not between items using different scaling factors (1:2 vs. 1:4), suggesting that participants encoded relative rather than absolute distances.  相似文献

该研究采用自然实验和问卷调查法,对268名小学五年级学生进行画图表征策略训练,在此基础上根据策略学习情况筛选出掌握了该策略的218名学生,以这些学生为被试,探讨元认知在画图表征策略和小学生数学问题解决能力中的作用。结果表明:(1)策略学习后,小学生的画图表征策略水平和数学问题解决成绩均显著高于策略学习前。(2)画图表征策略通过元认知这一中介变量对小学生数学问题解决能力有显著的促进作用。  相似文献

本研究采用注意瞬脱实验范式探讨了语义信息在数量表征中的作用。结果发现:(1)在双任务方式中,字母辨认任务对大数(5及以上)的辨认产生干扰,但不影响小数(4及以下)的辨认绩效;(2)数量表征在视野上出现差异性,表现为在小数辨认时,左侧视野呈现绩效高于右侧;大数辨认正好相反,即右侧视野呈现高于左侧。结果表明,语义信息在表征小数和大数中的作用不同:小数的表征无需语言参与;而大数则更多地涉及语义信息,可能需语音回路中无声复述机制的参与。  相似文献

Comparative rationality analysis formally examines the incommensurable social rationalities that theoretically exist within religions and the social sciences according to the ideological surround model (ISM) of the psychology of religion. This study extended these procedures to a new cultural context: 220 Iranian university students responded to the Religious Problem‐Solving Scales developed by Pargament et al. (1988). As hypothesized, the Collaborative Problem‐Solving Style was consistent, and the Self‐Directing Style inconsistent, with Iranian Muslim religious and psychological adjustment. The Deferring Style had ambiguous implications. Comparative rationality analysis demonstrated that sample interpretations of these styles explained greater variance in adjustment than did the original scales. These procedures also yielded the unexpected discovery that the Deferring Style included a secular as well as a religious form of Iranian rationality. These data most importantly support the ISM claim that “future objectivity” requires empirical analyses of the incommensurable rationalities operating within the psychology of religion.  相似文献
