We investigate the relationship between two approaches to modeling physical systems. On the first approach, simplifying assumptions
are made about the level of detail we choose to represent in a computational simulation with an eye toward tractability. On
the second approach simpler, analogue physical systems are considered that have more or less well-defined connections to systems
of interest that are themselves too difficult to probe experimentally. Our interest here is in the connections between the
artifacts of modeling that appear in these two approaches. We begin by outlining an important respect in which the two are
essentially dissimilar and then propose a method whereby overcoming that dissimilarity by hand results in usefully analogous
behavior. We claim that progress can be made if we think of artifacts as clues to the projectible predicates proper to the
models themselves. Our degree of control over the connection between interesting analogue physical systems and their targets
arises from determining the projectible predicates in the analogue system through a combination of theory and experiment.
To obtain a similar degree of control over the connection between large-scale, distributed simulations of complex systems
and their targets we must similarly determine the projectible predicates of the simulations themselves. In general theory
will be too intractable to be of use, and so we advocate an experimental program for determining these predicates.

Researchers have increasingly investigated the role played by metacognition in students' learning and performance. Metacognition is comprised of metacognitive knowledge and metacognitive experiences, and both components of metacognition are viewed as being important to learning and performance in academic settings. Metacognitive experiences involve, in part, students' awareness of progress on cognitive tasks. Such awareness is critical to learning, for students may fail to spend additional time reviewing or studying material if they believe they have understood the material adequately. In the present study we examined Taiwanese students' ability to assess their comprehension of passages following reading as well as their ability to predict the number of questions they would be able to answer about passage content. Following an actual test on the material, students were asked to assess how many questions they felt they answered correctly about a passage (postdiction). Students were able to predict comprehension and test performance at better than chance levels and were more accurate at postdiction than prediction. Students with better performance, as measured by comprehension test scores, were better at both prediction and postdiction of comprehension performance. However, students' self-assessments of general calibration ability did not relate to their test performance. The metacomprehension skills of Taiwanese students were quite similar to those previously found for western students, but also diverged in some respects. 相似文献

As prejudice becomes more subtle in its manifestations, members of stigmatized groups must often contend with the ambiguity of not knowing whether others are biased against them. In this study, we tested whether explicitly communicated gender prejudice would facilitate women’s performance on a difficult task compared to contexts where such discrimination might be possible but is not explicitly communicated. The findings revealed that the task performance of women who are chronically concerned about gender discrimination suffered when a male interviewer’s gender attitudes were ambiguous, relative to when his attitudes were either explicitly chauvinistic or explicitly egalitarian. As expected, the performance of women low in discrimination concerns was not affected by the experimental manipulation. The findings are discussed in light of growing evidence for the ironic effects of prejudice for the targets of stigma. 相似文献

Teaching with acoustical guidance involves auditory feedback (e.g., a click sound when a desired behavior occurs) as part of a multicomponent intervention known as TAGteach. TAGteach has been found to improve performance in sport, dance, surgical technique, and walking. We compared the efficacy and efficiency of the standard TAGteach error-correction procedure and a modified TAGteach error-correction procedure to teach 4 novice adult yoga practitioners beginner yoga poses. Both error-correction procedures were effective for all participants; however, the relative efficiency of these error-correction procedures was unclear. Results are discussed in terms of limitations and considerations for future research. 相似文献

In three experiments, 165 adult participants were trained on 12 baseline conditional discriminations and tested for the formation of three 5-member equivalence classes (A➔B➔C➔D➔E). All experiments included two reference groups; the abstract (ABS) group was trained with all abstract stimuli and the picture (PIC) group with C-stimuli as meaningful pictorial stimuli but A, B, D, and E stimuli as abstract shapes. In Experiment 1, the color of the meaningful stimuli was manipulated. In the ABS, PIC, and black-and-white groups, 33.3%, 80%, and 93.3% formed equivalence classes, respectively. In Experiment 2, participants were exposed to a test block with and without trials that included C stimuli. For the groups with and without C trials in the test, 93.3% and 86.7% formed equivalence classes, respectively, compared to 20% in the ABS group. In Experiment 3, the number of meaningful pictures and their location in stimulus classes were manipulated. One group was trained with 3 pictures (C1/B2/D3, the 3-PIC) while the other groups had 2 pictures (C1/B2 and C1/D3, the 2-PIC). In the second test block for the ABS and PIC groups, 6.7% and 86% of the participants formed equivalence classes, respectively. For the 3-PIC and the 2-PIC groups, 66.7% and 50% of the participants formed equivalence classes, respectively. Results suggest that the effects of meaningful stimuli in equivalence classes (a) cannot be attributed to the use of colorful stimuli in previous studies, (b) occur during training and are not dependent on the presence of meaningful stimuli at test, and (c) are sensitive to stimulus location. 相似文献

The present research examined the role of thinking mode for accuracy in recruiters and laypeople’s judgments of applicants’ cognitive ability. In Study 1, students who relied on their intuition were somewhat less accurate. In Study 2, an experimental manipulation of thinking mode (intuitive vs analytical) revealed no apparent differences in accuracy. Moreover, there were no differences in accuracy or agreement between recruiters and laypeople. Examination of the use of specific resume content suggested that intuitive thinking corresponds to basing one’s judgments more on the way that applicants present themselves in their personal letter and less on diagnostic biographical information such as SAT scores. The findings point to the possibility that professional recruiters may not possess intuitive expertise in this context. 相似文献

Junzi personality refers to traits of ideal persons in Confucian philosophy and is a key to East-Asian indigenous personality studies. We proposed that Junzi personality predicts positive interpersonal relationships, mediated by internal and external attributions in affiliation goal areas. Participants from China (N = 337) completed self- and peer-rated questionnaires in three stages over a 4-month period. Results showed that Junzi personality significantly and positively predicted self-rated interpersonal competence and satisfaction and peer ratings of interpersonal performance. These effects were significantly mediated by internal and external attributions for affiliation. This research provides personality and interpersonal psychology insights by culturally compatible measures and frameworks rooted in East-Asian philosophy and also contributes to the literature on antecedents and consequences of affiliation attribution. 相似文献

Research suggests that the electrophysiological correlates of consciousness are similar in hearing as in vision: the auditory awareness negativity (AAN) and the late positivity (LP). However, from a recently proposed signal-detection perspective, these correlates may be confounded by performance, as the strength of the internal responses differs between aware and unaware trials. Here, we tried to apply this signal-detection approach to correct for performance in an auditory discrimination and detection task (N = 28). A large proportion of subjects had to be excluded because even a small response bias distorted the correction. For the remaining subjects, the correction mainly increased noise in the measurement. Furthermore, the signal-detection approach is theoretically problematic because it may isolate post-perceptual processes and eliminate awareness-related activity. Therefore, we conclude that AAN and LP are not confounded by performance and that the contrastive analysis identifies both as correlates of awareness. 相似文献

It is incontestable that high motor performance requires an optimal coupling between perception and action. In sports as well as in professional tasks, the Quiet Eye (QE) – defined as the final fixation before movement initiation – has been found to explain a considerable amount of variance in motor performance and expertise. In the current series of studies, the underlying mechanisms of this perception-action variable were further investigated by testing predictions of the inhibition hypothesis. According to the inhibition hypothesis, the functionality of the QE is to shield movement parametrization. By manipulating the demands during response selection (Experiment 1 and Experiment 2) and movement control (Experiment 2) in a far-aiming task, it was found that – in line with the predictions – QE duration increased with increasing inhibition demands. This effect was mainly driven by the similarity rather than the number of possible actions. Moreover, the relation between inhibition demands and QE-duration were sustained through both response selection and movement control, which is perfectly in line with the notion of a continuous perception-action cycle in motor behavior. In sum, these findings corroborate the inhibition function as an integral component within a cognitive understanding of the QE phenomenon. 相似文献
