Lynn has published a series of papers on cross-cultural comparison of IQs. In three of his papers, Lynn indicated that the Japanese performed higher on IQ tests, and analyzed this from a socio-ecological point of view. This paper presents a comparison of intellectual abilities of Japanese and American children on the Columbia Mental Maturity Scale (CMMS). 相似文献

Co-orientation by capuchin (Cebus apella) and squirrel (Saimiri sciureus) monkeys in response to familiar humans abruptly switching the direction of their visual attention was recorded. Co-orientation occurred more frequently overall in capuchins than squirrel monkeys. Capuchins showed a tendency to habituate within trials involving consecutive attention switches performed by 2 different people, whereas squirrel monkeys co-oriented more when the 2nd attention switch was by a 2nd actor. These results suggest variable attention-processing abilities in New World monkeys, including differences in summation of attention by others. 相似文献

Researchers have investigated to what extent non-human primates understand others’ attentional states, as this ability is considered an important prerequisite for theory of mind. However, previous studies using food requesting tasks have failed to show that non-human primates attribute perception to others as a function of their attentional states. One possible reason is that food requesting tasks may require subjects not only to take into account an experimenter’s attentional state but also to direct it toward the food. The present study tested tufted capuchin monkeys’ (Cebus apella) understanding of others’ attentional states in a food requesting task. In the first situation, monkeys were required only to attract an experimenter’s attention. In the second situation, the monkeys were required to both attract the experimenter’s attention and direct it toward food on a table. The results revealed that capuchin monkeys showed evidence of understanding the experimenter’s attentional variations only in the former condition. This suggests that previous tasks, requiring referential gestures, lacking in most non-human primates, failed to reveal sensitivity to human attentional states because the subjects might not have understood the requesting situation. In conclusion, capuchin monkeys can understand variations in others’ attentional states, although this ability appears limited compared to what is seen in humans. 相似文献

This study investigates the influence of affective states on the use of implicit hints when solving insight problems. To examine this, two experiments were conducted, both with Duncker's (1945) radiation problem as an insight problem. When primed with a hint, positive affect inhibited the number of incorrect solutions generated in Experiment 1 and increased the number of correct solutions in Experiment 2. In contrast, negative affect enhanced the participants’ performance regardless of the presence of hints across the two experiments. These results indicate that positive and negative affect facilitate insight problem‐solving in different ways. It seems that positive affect implicitly prompts the acceptance of cues and broadens people's search of a problem space, and negative affect encourages people to intensively focus on solving the insight task. The results suggest a resolution of a long‐standing debate on the effectiveness of positive versus negative affect in solving a problem. 相似文献

Perception of a briefly presented target is impaired when a sparse surrounding mask (e.g., four-dot) persists after target offset compared to when the target and mask offset together (i.e., object substitution masking [OSM]). Previous studies have reported a mask preview effect in which OSM is largely attenuated by prior presentation of the mask. Here, we investigated how breaking object continuity of the previewed mask affects the mask preview effect. Introducing an abrupt surface color change of the previewed mask at target onset disrupted the beneficial effect of mask preview, that is, OSM was reinstated (Experiment 1). The masking induced by mask color change exhibited the same two characteristics as conventional OSM: target location specificity and non-necessity of voluntary attention to the mask (Experiment 2). These results suggest that a sudden change in surface color breaks object continuity of the previewed mask and causes the mask to be represented as a new one, which triggers OSM anew. 相似文献

Using an experimentally induced cooperation task, the authors investigated whether tufted capuchin monkeys (Cebus apella) share the following 3 characteristics of cooperation with humans: division of labor, communication, and reciprocal altruism. In Experiment 1, the authors trained individual monkeys to perform the necessary sequence of actions for rewards and tested them in pairs to assess whether they could solve the task by spontaneously dividing the sequence of actions. All pairs solved this task. In Experiment 2, monkeys worked in the cooperation task and a task requiring no partner help. They looked at the partner significantly longer in the former task than in the latter, but communicative intent could not be determined. In Experiment 3, only 1 of 2 participants obtained a reward on each trial. Monkeys maintained cooperation when their roles were reversed on alternate trials. Their cooperative performances demonstrated division of labor; results suggest task-related communication and reciprocal altruism. 相似文献

The present study asked whether capuchin monkeys recognize human attentional states. The monkeys requested food from the experimenter
by extending an arm (pointing) toward the baited one of two transparent cups. On regular trials the experimenter gave the
food immediately to the monkeys upon pointing but on randomly inserted test trials she ignored the pointing for 5 s during
which she displayed different attentional states. The monkeys looked at the experimenter's face longer when she looked at
the monkeys than when she looked at the ceiling in Experiment 1, and longer when she oriented her head midway between the
two cups with eyes open than when she did so with eyes closed in Experiment 2. However, the monkeys showed no differential
pointing in these conditions. These results suggest that capuchins are sensitive to eye direction but this sensitivity does
not lead to differential pointing trained in laboratory experiments. Furthermore, to our knowledge, this is the first firm
behavioral evidence that non-human primates attend to the subtle states of eyes in a food requesting task. 相似文献

Causal induction in the real world often has to be quick and efficient as well as accurate. We propose that people use two different frames to achieve these goals. The A-frame consists of heuristic processes that presuppose rarity and can detect causally relevant factors quickly. The B-frame consists of analytic processes that can be highly accurate in detecting actual causes. Our dual frame theory implies that several factors affect whether people use the A-frame or the B-frame in causal induction: among these are symmetrical negation, intervention and commitment. This theory is tested and sustained in two experiments. The results also provide broad support for dual process accounts of human thinking in general. 相似文献

In exploratory factor analysis, factor rotation is conducted to improve model interpretability. A promising and increasingly popular factor rotation method is geomin rotation. Geomin rotation, however, frequently encounters multiple local solutions. We report a simulation study that explores the frequency of local solutions in geomin rotation and the implications of such phenomena. The findings include: (1) multiple local solutions exist for geomin rotation in a variety of situations; (2) ? = .01 provides satisfactory rotated factor loadings in most situations; (3) 100 random starts appear sufficient to examine the multiple solution phenomenon; and (4) a population global solution may correspond to a sample local solution rather than the sample global solution. 相似文献

In the present study, we investigated how brain images affect metacomprehension judgments of neuroscience research. Participants made a prereading judgment of comprehension of the text topic and then read a text about neuroimaging findings. In Experiment 1, participants read text only or text accompanying brain images. In Experiment 2, participants read text accompanying bar graphs or text accompanying brain images. Then participants were asked to rate their comprehension of the text. Finally, they completed comprehension tests. The results of Experiment 1 showed that the text accompanying brain images was associated with higher metacomprehension judgments than was the text only, whereas the performance of the comprehension test did not differ between each condition. The results of Experiment 2 showed that the text accompanying brain images was associated not only with credibility of the text, but also with higher metacomprehension judgments than was the text accompanying the bar graphs, whereas the performance of the comprehension test did not differ between each condition. The findings suggest that the readers’ subjective judgments differ from actual comprehension. 相似文献
