Behavioral and neurophysiological transfer effects from music experience to language processing are well-established but it is currently unclear whether or not linguistic expertise (e.g., speaking a tone language) benefits music-related processing and its perception. Here, we compare brainstem responses of English-speaking musicians/non-musicians and native speakers of Mandarin Chinese elicited by tuned and detuned musical chords, to determine if enhancements in subcortical processing translate to improvements in the perceptual discrimination of musical pitch. Relative to non-musicians, both musicians and Chinese had stronger brainstem representation of the defining pitches of musical sequences. In contrast, two behavioral pitch discrimination tasks revealed that neither Chinese nor non-musicians were able to discriminate subtle changes in musical pitch with the same accuracy as musicians. Pooled across all listeners, brainstem magnitudes predicted behavioral pitch discrimination performance but considering each group individually, only musicians showed connections between neural and behavioral measures. No brain-behavior correlations were found for tone language speakers or non-musicians. These findings point to a dissociation between subcortical neurophysiological processing and behavioral measures of pitch perception in Chinese listeners. We infer that sensory-level enhancement of musical pitch information yields cognitive-level perceptual benefits only when that information is behaviorally relevant to the listener. 相似文献

We assessed the effects of time-on-task on cognitive control expressed by the CRN/Nc and the extent to which motivation modulates this relationship. We utilized two groups of participants, who were told that their performance would (evaluation condition) or would not (control condition) be evaluated online. Both groups performed a version of the Eriksen Flanker Task for 60 min. We observed classical vigilance lowering, manifested by a progressive performance decline with time-on-task, in the control, but not in the evaluation, condition. In the latter, performance remained stable throughout the task. ERP analysis indicated the same interaction in our main component of interest, the CRN/Nc, whose amplitude decreased from the first to the last period in the control condition but remained stable over time in the evaluation condition. To our knowledge, this study is the first to demonstrate the impact of motivation on monitoring processes as indexed by the correct response negativity, in the context of a prolonged task. Vigilance lowering caused by a repetitive and prolonged flanker task, results in compromised response control and compromised control of correct responses. Our results suggest that alterations in ACC functioning may underlie vigilance decline and can be viewed as evidence that the action monitoring functions of the ACC can be positively affected by motivation. 相似文献

Exposure to severe air pollution produces neuroinflammation and structural brain alterations in children. We tested whether patterns of brain growth, cognitive deficits and white matter hyperintensities (WMH) are associated with exposures to severe air pollution. Baseline and 1 year follow-up measurements of global and regional brain MRI volumes, cognitive abilities (Wechsler Intelligence Scale for Children-Revised, WISC-R), and serum inflammatory mediators were collected in 20 Mexico City (MC) children (10 with white matter hyperintensities, WMH+, and 10 without, WMH−) and 10 matched controls (CTL) from a low polluted city. There were significant differences in white matter volumes between CTL and MC children - both WMH+ and WMH− - in right parietal and bilateral temporal areas. Both WMH− and WMH+ MC children showed progressive deficits, compared to CTL children, on the WISC-R Vocabulary and Digit Span subtests. The cognitive deficits in highly exposed children match the localization of the volumetric differences detected over the 1 year follow-up, since the deficits observed are consistent with impairment of parietal and temporal lobe functions. Regardless of the presence of prefrontal WMH, Mexico City children performed more poorly across a variety of cognitive tests, compared to CTL children, thus WMH+ is likely only partially identifying underlying white matter pathology. Together these findings reveal that exposure to air pollution may perturb the trajectory of cerebral development and result in cognitive deficits during childhood. 相似文献

The war in Northern Uganda has ended, and youth who were abducted by the Lord's Resistance Army continue to return to communities. Research conducted in the summer of 2010 in two locations in Uganda, Gulu and Masindi, shows that the process of reintegration is an ongoing process in which formerly abducted youth (FAY) negotiate social relations for reintegration in a very interactive way. FAY consciously decide to stay quiet about their past to avoid compromising social reintegration. The experience‐oriented approach has allowed for an in‐depth exploration and understanding of the reintegration process from the perspective of FAY. In Northern Ugandan cosmology, meaning given to FAY personal spaces dominates. With FAY facing social exclusion by community members and the need to overcome boundaries to reintegration, coping mechanisms are adopted to facilitate reintegration and to carve out personal space within the Northern Ugandan cosmology. In the exploration of the process of negotiating reintegration, a conceptual model is adopted and adjusted to represent personal space within Northern Ugandan cosmology. The main findings suggest that FAY negotiate social relations for reintegration in a very interactive way and that they consciously decide to stay quiet about their past so as to not compromise social reintegration.

Individual differences in uncertainty have been associated with heightened anxiety, stress and approach-oriented coping. Intolerance of uncertainty (IU) is a trait characteristic that arises from negative beliefs about uncertainty and its consequences. Researchers have established the central role of IU in the development of problematic worry and maladaptive coping, highlighting the importance of this construct to anxiety disorders. However, there is a need to improve our understanding of the phenomenology of IU. The goal of this paper was to present hypotheses regarding the similarities and differences between IU and three related constructs – intolerance of ambiguity, uncertainty orientation, and need for cognitive closure – and to call for future empirical studies to substantiate these hypotheses. To assist with achieving this goal, we conducted a systematic review of the literature, which also served to identify current gaps in knowledge. This paper differentiates these constructs by outlining each definition and general approaches to assessment, reviewing the existing empirical relations, and proposing theoretical similarities and distinctions. Findings may assist researchers in selecting the appropriate construct to address their research questions. Future research directions for the application of these constructs, particularly within the field of clinical and health psychology, are discussed. 相似文献

Introduction and objectivesAfter leading a validation of questionnaires about three fundamental needs in French language (need for cognition, closing and evaluation), we tested in two studies that fundamental needs could be subjected to social constraints and could be considered differently than exclusively like stable personality characteristics and motivational drivers of action.MethodUsing the paradigm of judges (study 1) and the paradigm of identification (study 2), the results argue for a normative approach, at least as regards the need for cognition and assess.ResultsThe results of the first study show that individuals consider more favorably targets with strong need rather than low need and especially in social contexts with high social utility (that is to say, the professional context in comparison with the friendly context). The results of the second study show that when the questionnaires about needs “as would a person having been previously well or poorly assessed” participants get higher scores high on the need for cognition questionnaire in the first case than in the second. The results regarding the need for closure are more mixed.ConclusionThe results are discussed in a socio-normative perspective. 相似文献

What pedagogical skills are necessary for first-time college instructors? Ninety-two faculty (M = 41.3 years old, 68% female, 90.2% white, 91% born in the US) and 64 graduate students (M = 28.3 years old, 83% female, 87.5% white, 81% born in the US) listed the top three skills they believed were essential to instructors’ success in the college classroom. Despite differing levels of classroom teaching experience, graduate students and faculty members prioritized “survival” skills: public speaking, organization, and content mastery. Notable differences did emerge: faculty members were more likely to list reflection on teaching and graduate students were more likely to list classroom management and comfort with technology. Faculty also preferred more informal training methods (e.g., self-reflection, mentorship), whereas graduate students preferred more formal training methods (e.g., practice/experience, seminar/workshop). Recommendations for graduate teacher training programs include a focus on lower as well as higher-level skills and an attempt to incorporate formal and informal training methods. 相似文献

This article calls for international comparative research on the professionalisation of Religious Education (RE). To this end, it provides a rationale for focusing upon the concept of professionalisation and a theoretical justification for international comparative research, particularly identifying its significance in terms of the development of RE in England and Germany. The article outlines a methodology for exploring the concepts of professional knowledge, professional self-organisation and politics and professional development. The proposed methodology involves a systematic analysis of primary documentary sources including: (1) academic and professional journal articles and textbooks; (2) the archives of relevant institutions and organisations; and (3) external evidence, such as inspection and research reports. An analytical case study of two leading journals in each national context, Religion in Education in England and Der Evangelische Erzieher in Germany, in the immediate post-war era is appended to illustrate the benefits of implementing such a methodology across national boundaries. 相似文献
