To gain insight into human nature philosophers often discuss the inferior performance that results from deficits such as blindsight
or amnesia. Less often do they look at superior abilities. A notable exception is Herbert Dreyfus who has developed a theory
of expertise according to which expert action generally proceeds automatically and unreflectively. We address one of Dreyfus’s
primary examples of expertise: chess. At first glance, chess would seem an obvious counterexample to Dreyfus’s view since,
clearly, chess experts are engaged in deep strategic thought. However, Dreyfus’s argument is subtle. He accepts that analysis
and deliberation play a role in chess, yet he thinks that all such thought is predicated on intuitive, arational expert perception,
and action. We argue that even the so-called “intuitive” aspect of chess is rational through and through. 相似文献

Although the majority of research focuses on the risks and disadvantages of online gaming, the present authors suggest that
online games also represent new ways of satisfying basic human needs within the conditions of modern society. The aim of our
present study was to reveal and operationalize the components of the motivational basis of online gaming. A total 3,818 persons
(90.6% males; mean age 20.9 years, SD = 5.81) were recruited through websites providing online games. A combined method of exploratory and confirmatory factor
analysis was applied. The results confirmed our preliminary model as we identified seven motivational factors (social, escape,
competition, coping, skill development, fantasy, and recreation), which were used to develop the 27-item Motives for Online
Gaming Questionnaire (MOGQ). The seven dimensions identified seem to cover the full range of possible motives for gaming, and the MOGQ proved to be an
adequate measurement tool to assess these motives. 相似文献

Statistical prediction of an outcome variable using multiple independent variables is a common practice in the social and
behavioral sciences. For example, neuropsychologists are sometimes called upon to provide predictions of preinjury cognitive
functioning for individuals who have suffered a traumatic brain injury. Typically, these predictions are made using standard
multiple linear regression models with several demographic variables (e.g., gender, ethnicity, education level) as predictors.
Prior research has shown conflicting evidence regarding the ability of such models to provide accurate predictions of outcome
variables such as full-scale intelligence (FSIQ) test scores. The present study had two goals: (1) to demonstrate the utility
of a set of alternative prediction methods that have been applied extensively in the natural sciences and business but have
not been frequently explored in the social sciences and (2) to develop models that can be used to predict premorbid cognitive
functioning in preschool children. Predictions of Stanford–Binet 5 FSIQ scores for preschool-aged children is used to compare
the performance of a multiple regression model with several of these alternative methods. Results demonstrate that classification
and regression treesprovided more accurate predictions of FSIQ scores than does the more traditional regression approach.
Implications of these results are discussed. 相似文献

Strong cross-modal interactions exist between visual and auditory processing. The relative contributions of perceptual versus decision-related processes to such interactions are only beginning to be understood. We used methodological and statistical approaches to control for potential decision-related contributions such as response interference, decisional criterion shift, and strategy selection. Participants were presented with rising-, falling-, and constant-amplitude sounds and were asked to detect change (increase or decrease) in sound amplitude while ignoring an irrelevant visual cue of a disk that grew, shrank, or stayed constant in size. Across two experiments, testing context was manipulated by varying the grouping of visual cues during testing, and cross-modal congruency showed independent perceptual and decision-related effects. Whereas a change in testing context greatly affected criterion shifts, cross-modal effects on perceptual sensitivity remained relatively consistent. In general, participants were more sensitive to increases in sound amplitude and less sensitive to sounds paired with dynamic visual cues. As compared with incongruent visual cues, congruent cues enhanced detection of amplitude decreases, but not increases. These findings suggest that the relative contributions of perceptual and decisional processing and the impacts of these processes on cross-modal interactions can vary significantly depending on asymmetries in within-modal processing, as well as consistencies in cross-modal dynamics. 相似文献

In four visual search tasks participants were asked to make a target response if either of two targets was present and to make a nontarget response if neither target was present. Some target-absent displays included only nontarget stimuli or features that never occurred in the same displays as targets, whereas other target-absent displays included nontarget stimuli or features that did sometimes occur with targets. Nontarget responses were reliably faster in the former case than in the latter. This “associated nontargets effect” indicates that nontargets are not simply classified as nontargets but in addition are discriminated from one another. Current visual search models may underestimate the degree to which nontargets are processed during search. 相似文献

In the current study we examined the relationship between working memory capacity, inhibition/susceptibility to interference and fluid intelligence, measured by the Raven's Progressive Matrices (PM38), comparing groups of young (aged 18–35), young-old (aged 65–74), and old-old (aged 75–86) participants. Groups were administered two working memory tasks tapping into different mechanisms involved in working memory. The ability to control for irrelevant information was measured both considering memory errors (intrusion errors) in a working memory task and an index of susceptibility to interference obtained with a variant of the Brown-Peterson task. Regression analyses showed that the classical working memory measure was the most potent predictors of the Raven's score. Susceptibility to interference and intrusions errors contributed, but to a lower extent, to the Raven explained variance. These results confirm that working memory shares cognitive aspects with the fluid intelligence measure considered, whereas the role of inhibition to Raven scores is still in need of better evidence. 相似文献

The authors explored attitudes of young women in the United Kingdom (n = 108) and the United States (n = 91) toward (a) the possession and use of guns through the Attitude to Guns Scale (N. R. Branscombe, J. A. Weir, & P. Crosby, 1992) and (b) guns' perceived functional and symbolic significance through the Symbolic Nature of Guns Scale (C. A. Cooke & J. E. Puddifoot, 1997). There were significant differences in beliefs concerning the right to own a gun and the protective effect of guns but not in the perceived contribution of guns to crime. Although neither group strongly equated guns symbolically with power or control, the U.S. women were more likely to perceive guns as expressions of freedom or independence, and the U.K. women were more likely to view guns as expressions of danger and violence. The findings were contextualized by comparison with samples of male control participants of similar ages. 相似文献
