Error and preservation patterns in aphasic speech show that the brain makes use of the frequencies of words, constructions, and collocations, as well as category membership and hierarchical structure, during language processing. Frequency effects are evident along two quasi‐independent axes: syntagmatic (the sequential context, e.g., deploying correct functors, categories, and utterance‐level intonation) and paradigmatic (the choice at any given linguistic level, e.g., selecting content words and modifying structures). Frequency along the syntagmatic axis is shown to play a role in errors involving idioms, constructions, and collocations that cross major phrasal boundaries. Along the paradigmatic axis, frequency affects errors involving lexical selection, competing functors and inflected forms (e.g., using plural where singular is required). An account of language representation and processing that encompasses frequency as well as categorization and structure is compatible with what we know about how the brain works: increased experience with a linguistic structure results in increased activation—and strengthening—of the neural networks involved in processing that structure. These claims are supported by the literature on experimental work in normal speakers. Parsimony, plus the unexamined assumption that mental representation is like a written record (entries either present or absent, structure displayable in two dimensions), has been a misleading guide to modeling language representation. The substantial redundancy in representations and processing that is introduced by incorporating both frequency‐based and hierarchy‐based information is in fact appropriate for the brain as a fast, reliable, massively parallel error‐correcting network with very large storage capacity and gradient representation strength.

American students transitioning to university are at an increased risk for behaviours such as binge drinking, depression and suicidality. Despite the proliferation of prevention and intervention programs, rates remain high. Although religiosity is known to confer a protective effect in this population, it remains largely untapped as a resource because, among other reasons, it is poorly understood, poses ethical challenges, and exposes areas of distrust between the religious and medical establishments. This report describes the findings of a survey that examined possible factors explaining the relationship between religiosity, risky behaviours and emotional extremes in students as they transitioned into their first year of university. This study accounted for the religious diversity of the US by surveying Christian, Jewish, Muslim and religiously unaffiliated students. Findings indicated that religiosity was consistently and negatively correlated to risky behaviours across all faith groups. Interestingly, unique patterns in levels of religiosity emerged among the various faith groups. Similarly, patterns of engagement in risky behaviours demonstrated variation among religious groups. Our findings add to the body of evidence that suggests university-based professionals take into consideration student religiosity when creating prevention intervention programs for students. 相似文献

Two studies investigated the efficacy of 3 theoretical models in explaining college students judgments of peers who cheat and of accomplices who assist cheaters. The value pluralism model predicted that accomplices who acted for money would be judged more harshly than those who acted from friendship; the attributional model predicted that cheaters whose actions were caused by internal controllable factors would be judged more harshly than those who actions were caused by external uncontrollable factors, and the relative preference model predicted that students who saw themselves as more likely to act as the cheater and accomplice did would make less harsh judgments. Overall, the results provided the best support for the relative preference model. 相似文献

Using a sample of 391 low-income youth ages 13–17, this study investigated the potential moderating effects of school climate, participation in extracurricular activities, and positive parent–child relations on associations between exposure to violence (i.e., witnessing violence and violent victimization) and adolescent socioemotional adjustment (i.e., internalizing and externalizing problems). Exposure to violence was related to both internalizing and externalizing problems. High levels of participation in extracurricular activities and positive parent–child relations appeared to function as protective factors, weakening the positive association between exposure to violence and externalizing problems. Contrary to prediction, school climate did not moderate associations between exposure to violence and socioemotional adjustment. Further, none of the hypothesized protective factors moderated the association between exposure to violence and internalizing problems. 相似文献

The purpose of this study was to examine self-regulation as a mediator of the relation between family functioning and externalizing behaviour in 731 low-income children (M age = 41 months) across three time points. Specifically, this study focused on whether chaos in the home and positive behaviour support were indirectly related to externalizing problems through their influence on inhibitory control. The primary findings were as follows: (a) chaos in the home at age 3 years was indirectly related to externalizing behaviour at age 5.5 years through children's inhibitory control at age 4 years, and (b) positive behaviour support at age 3 years was indirectly related to externalizing behaviour at age 5.5 years through inhibitory control at age 4 years. Implications of these findings and directions for future research are discussed. 相似文献

Removing the shadow of suspicion: the effects of apology versus denial for repairing competence- versus integrity-based trust violations 总被引：7，自引：0，他引：7
Two studies were conducted to examine the implications of an apology versus a denial for repairing trust after an alleged violation. Results reveal that trust was repaired more successfully when mistrusted parties (a) apologized for violations concerning matters of competence but denied culpability for violations concerning matters of integrity, and (b) had apologized for violations when there was subsequent evidence of guilt but had denied culpability for violations when there was subsequent evidence of innocence. Supplementary analyses also revealed that the interactive effects of violation type and violation response on participants' trusting intentions were mediated by their trusting beliefs. Combined, these findings provide needed insight and supporting evidence concerning how trust might be repaired in the aftermath of a violation. 相似文献

This article examines how academic disengagement (being off task, unenthusiastic and uncurious about learning) is facilitated by the hidden curriculum (the values, norms and beliefs transmitted via the structure of schooling), and mediated by race, ethnicity and gender for students in a working class elementary school. Additionally, we contextualize how a teacher was challenged by the hidden curriculum in her attempt to make her classroom environment engaging for all students. Participants included a young white female teacher and 21 second grade, low‐income students, of whom approximately 50% were white and 50% were Black or Latino/a. A teacher interview and fieldnotes covering 8 hours a week over 3 months comprised the data. Results indicated that students were required to show their engagement in particular ways that related to control and conformity. When they did not, they were reprimanded, which led to academic disengagement and the transmission of the hidden curriculum's message that school was not a place for them. This process was especially salient for Black and Latino boys, which indicated that the hidden curriculum was institutionalized. Results also showed that the hidden curriculum was a structural limitation for the teacher, as she was often thwarted in her attempts to create an academically engaging learning environment. Implications include strategies for school change and reform, including making the hidden curriculum more visible. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献
