For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.  相似文献

The current study compared general, work-specific, and work-role measures of conscientiousness as predictors of job satisfaction, organizational commitment, turnover intention, job engagement, and task performance. As expected, work-role conscientiousness yielded stronger relationships with five of the ten work-related criteria than general conscientiousness, and with six of the ten criteria than work-specific conscientiousness. More importantly, work-role conscientiousness displayed incremental validity in predicting nearly all work-related criteria, when controlling for general and work-specific conscientiousness alone or in combination. It is also worth noting that six of ten analyses found that work-role conscientiousness demonstrated greater relative importance compared to its counterparts. Finally, we found that the context in which the items were completed moderated the relationships between work-role conscientiousness and two work-related criteria (i.e., job satisfaction and organizational commitment). Together, these results suggest that researchers should consider the work-role measure of conscientiousness in the prediction of work criteria.  相似文献

The distinction between occurrent and non-occurrent mental states is frequently appealed to by contemporary philosophers, but it has never been explicated in any significant detail. In the literature, two accounts of the distinction are commonly presupposed (and occasionally stated explicitly). One is that occurrent states are conscious states. The other is that non-occurrent states are dispositional states, and thus that occurrent states are manifestations of dispositions. I argue that neither of these accounts is adequate, and therefore that another account is needed. I propose that occurrent states are active states.  相似文献

In their paper “Do Bilinguals Automatically Activate Their Native Language When They Are Not Using it?”, Costa, Pannunzi, Deco, and Pickering (Cognitive Science, 2017) proposed a reinterpretation of Thierry and Wu's (2004, 2007) finding of native language‐based (Chinese, L1) ERP effects when they tested Chinese–English late bilinguals exclusively in their second language (English, L2). Using simulations in a six‐node Hebbian learning model (three L1 nodes, three L2 nodes), Costa et al. suggested that form overlaps in L1 between otherwise unrelated words create a persistent relationship between their L2 translations. In this scenario, words in the nascent L2 lexicon overlapping in their L1 translations would become linked during learning because of the form overlap in L1; once the L2 words are learned, the direct link between them would be sufficient to generate robust, apparently “L1‐mediated” priming without requiring any activation of L1 translations. Costa et al. contend that links between L2 words remain beyond the learning phase, even after links to L1 representations have been severed, and thus that their model affords an alternative account to (but not a rebuttal of) Thierry and Wu's claim of language non‐selective activation—or automatic activation of translation equivalents—in late bilinguals. In this response, we build on Costa et al.'s original simulation code, showing that it can only reproduce L1‐independent priming when implementing the L1 disconnection in their particular way. By contrast, when severing inter‐language connections bidirectionally, their model fails to retain any sizeable influence of L1 form overlap on L2 activations. The model is not the theory, however, and we discuss several issues that would need to be addressed in further attempts to model language non‐selective activation in late bilinguals.  相似文献

It is often said that to love someone we must love her for her own sake. But what does this mean? Various answers have been offered up by philosophers. Alan Soble's ‘aggregate’ view of identity focuses on properties of the beloved as key to understanding love's basis and, in a less direct way, its object. This view does not give us a clear distinction between persons and properties. David Velleman's view makes this distinction more clearly but creates a gap between properties and personhood. Jean‐Paul Sartre's view which emphasizes embodiment, addresses the main deficiencies of both of these former views.  相似文献
