The key developments of two decades of connectionist parsing are reviewed. Connectionist parsers are assessed according to their ability to learn to represent syntactic structures from examples automatically, without being presented with symbolic grammar rules. This review also considers the extent to which connectionist parsers offer computational models of human sentence processing and provide plausible accounts of psycholinguistic data. In considering these issues, special attention is paid to the level of realism, the nature of the modularity, and the type of processing that is to be found in a wide range of parsers. 相似文献

Thomas Aquinas is often thought to present a compositionalist model of the incarnation, according to which Christ is a composite
of a divine nature and a human nature, understood as concrete particulars. But he sometimes seems to hedge away from this
model when insisting on the unity of Christ. I argue that if we interpret some of his texts on the assumption of straightforward
compositionalism, we can construct a defence of Christ’s unity within that context. This defence involves the claim that the
divine unity is so great, and the relation between Christ’s two natures so unusual, that the divine unity can be transferred
to the composite Christ as a “borrowed property”. 相似文献

To investigate the effect of a social audience on learning-by-teaching, we examined participants' solutions of the 4-ring Tower of Hanoi problem after they demonstrated the 3-ring problem to a social agent (a person) or a non-social agent (a computer). In Introduction, Discussion participants produced less optimal solutions of the 4-ring problem after demonstrating the 3-ring problem to a social agent. An analysis of pointing behavior demonstrated that social highlighting contributed substantially to this effect. Together, these findings indicate that more social highlighting may produce a cost, rather than a benefit, on how deeply the demonstrator encodes the problem solution. Experiment 3 clarified that these results were not simply caused by the disruptions inherent to social highlighting. Taken together, the results suggest that social highlighting does not come for free — producing the highlighting may lead to more shallow encoding of demonstrated actions. 相似文献

The cups task is the most widely adopted forced-choice paradigm for comparative studies of inferential reasoning by exclusion. In this task, subjects are presented with two cups, one of which has been surreptitiously baited. When the empty cup is shaken or its interior shown, it is possible to infer by exclusion that the alternative cup contains the reward. The present study extends the existing body of comparative work to include human children (Homo sapiens). Like chimpanzees (Pan troglodytes) that were tested with the same equipment and near-identical procedures, children aged three to five made apparent inferences using both visual and auditory information, although the youngest children showed the least-developed ability in the auditory modality. However, unlike chimpanzees, children of all ages used causally irrelevant information in a control test designed to examine the possibility that their apparent auditory inferences were the product of contingency learning (the duplicate cups test). Nevertheless, the children's ability to reason by exclusion was corroborated by their performance on a novel verbal disjunctive syllogism test, and we found preliminary evidence consistent with the suggestion that children used their causal-logical understanding to reason by exclusion in the cups task, but subsequently treated the duplicate cups information as symbolic or communicative, rather than causal. Implications for future comparative research are discussed. 相似文献

The association between personality and organizational citizenship behaviors is rarely examined in student populations. The present research tested the hypothesis that conscientiousness, agreeableness, and neuroticism predict unique variance in academic citizenship attitudes. In the first study, 270 college students completed an online questionnaire assessing their personality and academic citizenship attitudes. The results confirmed the hypothesis. In Study 2, we also tested the hypothesis that academic citizenship attitudes mediate the association between personality and citizenship behavior. Participants (n = 50) completed the online questionnaire. At a later session, they were asked to engage in an extra‐role helping behavior after completing the assigned task. The results showed that general conscientiousness was associated with citizenship behavior, but academic conscientiousness attitudes mediated this association. 相似文献

Because even subtle forms of racial discrimination can damage well-being, identifying individual differences that shape this stress process is important. Dispositional forgiveness has been shown to influence how people perceive and react to interpersonal transgressions, yet its role in the context of racial discrimination has not received much research attention. In the current study, participants completed an initial measure of dispositional forgiveness and then considered a scenario that could be deemed racially discriminatory. Next, participants' perceptions of the scenario, negative affect, and cognitive performance were assessed. Dispositional forgiveness predicted all three outcomes such that more forgiving individuals were less likely to view the event as racially discriminatory and showed lower negative affect and greater cognitive performance after reading the scenario. Moreover, race moderated these relationships such that forgiveness played a more beneficial role for ethnic minorities than for whites. 相似文献

Recent research has demonstrated that people have an affinity for non-human entities that appear to have human qualities. The current studies build on this research, examining whether anthropomorphism can be used to promote animal welfare. In Study 1 (n = 42), participants read scenarios about dogs and reported more willingness to help the ones described with anthropomorphic language relative to those described with non-anthropomorphic language. In Study 2 (n = 57), participants rated dogs on either human or canine characteristics (e.g., good listener vs. good at listing to commands). Relative to the non-anthropomorphism condition, participants in the anthropomorphism condition reported more willingness to adopt dogs from a shelter, and more support for animal rights, animal welfare, and vegetarian and vegan attitudes. Moreover, these pro-animal attitudes fully mediated the effect of the anthropomorphism manipulation on willingness to adopt the dogs. 相似文献

The individual self, relational self, and collective self are important and meaningful aspects of identity. However, they plausibly differ in their relative importance such that one self lies closer to the motivational core of the self-concept, better represent the “home base” of selfhood, or, simply stated, is motivationally primary. Four multi-method studies tested the relative motivational-primacy of the selves. Despite their disparate methods, the studies yielded consistent evidence of a three-tiered hierarchy with the individual self at the top, followed by the relational self, and trailed at the bottom by the collective self. The same hierarchy emerged in the Eastern culture of China and the Western cultures of the US and UK. Such pancultural consistency suggests that the motivational hierarchy is a fundamental pattern of the human self. 相似文献

Two longitudinal field experiments in a middle school examined how a brief "values affirmation" affects students' psychological experience and the relationship between psychological experience and environmental threat over 2 years. Together these studies suggest that values affirmations insulate individuals' sense of belonging from environmental threat during a key developmental transition. Study 1 provided an analysis of new data from a previously reported study. African American students in the control condition felt a decreasing sense of belonging during middle school, with low-performing students dropping more in 7th grade and high-performing students dropping more in 8th grade. The affirmation reduced this decline for both groups. Consistent with the notion that affirmation insulates belonging from environmental threat, affirmed African American students' sense of belonging in Study 1 fluctuated less over 2 years and became less contingent on academic performance. Based on the idea that developmentally sensitive interventions can have long-lasting benefits, Study 2 showed that the affirmation intervention was more effective if delivered before any drop in performance and subsequent psychological toll could unfold. The role of identity threat and affirmation in affecting the encoding of social experience, and the corresponding importance of timing treatments to developmentally sensitive periods, are explored. 相似文献

The empirical evidence that has accumulated in support of the notion that personality is a valid predictor of employee performance is vast, yet debate on the matter continues. This study investigates frame‐of‐reference effects as they relate to the validity of self‐report measures of personality. Specifically, we compare the validities of general, noncontextualized personality measures and work‐specific, contextualized measures. The findings suggest that personality measures are a more valid predictor of performance when the scale items or instructions are framed specifically so as to reference work‐specific behaviors. We found that the validities for noncontextualized measures of personality ranged from .02 to .22, with a mean validity of .11. The validities for contextualized measures ranged from .14 to .30, with a mean of .24 . Additional moderator analyses were conducted in an effort to examine several alternate explanations for these validity differences. Specifically, we examined differences between the developmental purpose (general use vs. workplace use) and reliabilities of each type of personality measure. We also compared the validities from published studies to those from unpublished studies. Results suggest that these moderators did not have an impact on the validity differences between noncontextualized and contextualized measures. 相似文献
