Whether our general numerical skills and the mathematical knowledge that we acquire at school are entwined is a debated issue, which many researchers are still striving to investigate. The findings reported in the literature are actually inconsistent; some studies emphasized the existence of a relationship between the acuity of the Approximate Number System (ANS) and arithmetic competence, while some others did not observe any significant correlation. One potential explanation of the discrepancy might stem from the evaluation of the ANS itself. In the present study, we correlated two measures used to index ANS acuity with arithmetic performance. These measures were the Weber fraction (w), computed from a numerical comparison task and the coefficient of variation (CV), computed from a numerical estimation task. Arithmetic performance correlated with estimation CV but not with comparison w. We further investigated the meaning of this result by taking the relationship between w and CV into account. We expected a tight relation as both these measures are believed to assess ANS acuity. Crucially, however, w and CV did not correlate with each other. Moreover, the value of w was modulated by the congruity of the relation between numerical magnitude and non-numerical visual cues, potentially accounting for the lack of correlation between the measures. Our findings thus challenge the overuse of w to assess ANS acuity and more generally put into question the relevance of correlating this measure with arithmetic without any deeper understanding of what they are really indexing. 相似文献

The surging interest in corporate psychopathy has underscored the need for a reliable and valid measure of psychopathic features that is suitable for research in organizational settings. The B‐Scan Self is a new self‐report measure of corporate psychopathy that was developed with Hare's Psychopathy Checklist‐Revised (PCL‐R) as a framework. Validity studies, using two independent Mechanical Turk samples, were designed to examine its factor structure and validity. Results indicated that B‐Scan Self facets were internally consistent and unidimentional and strongly related to another self‐report measure of psychopathy (SRP‐III). Confirmatory factor analyses supported a reliable fifteen facets and four‐factor model consistent with the PCL‐R four‐factor model of psychopathy. Furthermore, B‐Scan Self facets were positively correlated with the Dark Triad of personality traits and negatively correlated with FFM traits of Agreeableness and Conscientiousness. More importantly, B‐Scan Self facets presented the same pattern of correlations with FFM traits as the SRP‐III and different patterns than the two other Dark Triad measures. Although this constitutes the first validation study of the B‐Scan Self and more research is needed, we believe that these results are encouraging and that the B‐Scan Self provides an opportunity to study psychopathic features through the measure of work‐related behavior. 相似文献

After sketching an argument for radical anti-realism that does not appeal to human limitations but polynomial-time computability in its definition of feasibility, I revisit an argument by Wittgenstein on the surveyability of proofs, and then examine the consequences of its application to the notion of canonical proof in contemporary proof-theoretical-semantics. 相似文献

Recent work indicates that trying not to think in stereotypical terms increases the accessibility of stereotypical information, which paradoxically results in more stereotypical judgments. The present study translated the colour‐blindness ideology in general and stereotype suppression research in particular into an hypothesis testing setting. Participants who were asked to suppress their stereotypes when selecting a set of questions were indeed less guided by ambient stereotypes than control participants, thereby showing a reduction of the classical confirmation orientation in question preferences. Still, compared to control participants, suppressors also later reported more polarized impressions such that consistent targets were seen as more stereotypical and inconsistent ones as more counter‐stereotypical. Moreover, group evaluations were more stereotypical for suppressors than for controls indicating that suppression had led to stronger activation of the stereotypical representation. Results are discussed in light of the prevailing belief regarding the benefits of political correctness and colour‐blindness. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

While several cognitive domains have been widely investigated in the field of aging, the age-related effects on tool use are still an open issue and hardly any studies on tool use and aging is available. A significant body of literature has indicated that tool use skills might be supported by at least two different types of knowledge, namely, mechanical knowledge and semantic knowledge. However, neither the contribution of these kinds of knowledge to familiar tool use, nor the effects of aging on mechanical and semantic knowledge have been explored in normal aging. The aim of the present study was to fill this gap. To do so, 98 healthy elderly adults were presented with three tasks: a classical, familiar tool use task, a novel tool use task assessing mechanical knowledge, and a picture matching task assessing semantic knowledge. The results showed that aging has a negative impact on tool use tasks and on knowledge supporting tool use skills. We also found that aging did not impact mechanical and semantic knowledge in the same way, confirming the distinct nature of those forms of knowledge. Finally, our results stressed that mechanical and semantic knowledge are both involved in the ability to use familiar tools. 相似文献
