Language experience can alter perceptual abilities and the neural specialization for phonological contrasts. Here we investigated whether dialectal differences in the lexical use of pitch information lead to differences in functional lateralization for pitch processing. We measured cortical hemodynamic responses to pitch pattern changes in native speakers of Standard (Tokyo) Japanese, which has a lexical pitch accent system, and native speakers of ‘accentless’ dialects, which do not have any lexical tonal phenomena. While the Standard Japanese speakers showed left-dominant responses in temporal regions to pitch pattern changes within words, the accentless dialects speakers did not show such left-dominance. Pitch pattern changes within harmonic-complex tones also elicited different brain activation patterns between the two groups. These results indicate that the neural processing of pitch information differs depending on the listener’s native dialect, and that listeners’ linguistic experiences may further affect the processing of pitch changes even for non-linguistic sounds. 相似文献

This study examined whether the functional field of view shrinks by the presence of a weapon or the increase of emotional arousal. In Experiment 1, participants viewed two types of pictures depicting scenes involving weapons or control objects and were asked to identify digits presented at the periphery when the pictures disappeared. The results showed that the presence of a weapon impaired identification of the peripheral digits, even when the pictures were equal with respect to emotional arousal level. In Experiment 2, participants viewed emotionally arousing pictures or neutral pictures, neither of which included weapons, and they were asked to identify digits presented at the periphery when the pictures disappeared. The results revealed that the increased emotional arousal did not impair identification of the peripheral digits. These results indicate that the functional field of view shrinks because of the presence of a weapon but not because of increased emotional arousal.Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

We report the case of a 39-year-old, temporal lobe epileptic male, MH. Prior to complex partial seizure, experienced up to three times a day, MH often experiences an aura experienced as a persistent sensation of déjà vu. Data-driven theories of déjà vu formation suggest that partial familiarity for the perceived stimulus is responsible for the sensation. Consequently, diverting attention away from this stimulus should cause the sensation to dissipate. MH, whose sensations of déjà vu persist long enough for him to shift his perceptual focus a number of times during the experience, spontaneously reports that these shifts make no difference to the sensation experienced. This novel observation challenges data-driven theories of déjà vu formation which have been used to explain the occurrence of déjà vu in those with temporal lobe epilepsy and the general population. Clearly, in epilepsy, erratic neuronal firing is the likely contributor, and in this paper we postulate that such brain firing causes higher-order erroneous 'cognitive feelings'. We tentatively extend this account to the general population. Rather than being a reaction to familiar elements in perceptual stimuli, déjà vu is likely to be the result of a cognitive feeling borne of the erroneous activation of neural familiarity circuits such as the parahippocampal gyrus, persisting as long as this activation persists. 相似文献

In this study, we tested whether and how temporal information would affect the performance of numerosity discrimination in
sequential events, in an attempt to make the relationship clear between temporal and numerosity processing. We manipulated
the duration of event presentation (i.e., the stimulus duration) and the duration of the sequence (i.e., the total interval).
We also employed three levels of standard event numbers (i.e., 5, 10, and 20) to test whether and how the effect would differ
among event numbers. The results showed that temporal information affected the performance of numerosity discrimination; precision
deteriorated when stimulus duration and the total interval were manipulated, and the number of events in the longer total
interval were judged as less numerous than those in the shorter total interval across standard numbers. Accordingly, our results
suggested the existence of a shared system between time and numerosity processing. 相似文献

In this individual-differences study, we evaluated the prevalent view that relocating information in a previously read text depends primarily on visuospatial abilities. Participants read a text, answered fillin-the-blank test questions, and identified which page and line in the original text contained the sentence in each question. They also completed a battery of verbal and visuospatial tasks. Performance on verbal tasks was highly predictive of the accuracy of both page and line identifications, and this correlation remained significant even after we controlled for performance on visuospatial tasks. In contrast, performance on visuospatial tasks was not predictive of either page or line identification accuracy, once verbal abilities were controlled for. These results suggest an important role for verbal abilities in relocation of text information and a lesser role for visuospatial abilities than has previously been assumed. 相似文献

Japan disputes the sovereignty of two islands: Senkaku/Diaoyu with China and Takeshima/Dokdo with South Korea. These disputes have triggered political performances. In August 2012, Chinese activists landed on Senkaku/Diaoyu, and South Korean politicians landed on Takeshima/Dokdo. The group threat theory suggests that these events constitute threats to Japanese citizens, which lead to negative attitudes towards these countries. The theory also expects personal variations in the reactions to the threats, and the empirical findings of the theory predict an improvement in the worsened attitudes immediately after the event. Drawing on a Japanese social survey that was conducted every month for the two years during which these landing events occurred, I tested the effect of the events on Japanese attitudes towards China and South Korea in a natural experimental framework. The results show that the events negatively impacted Japanese attitudes towards both countries. However, contrary to the expectations of the group threat theory, individual variations (i.e., socioeconomic status, media exposure, and political orientation) in the responses to the events are not supported. Additionally, the attitudes do not return to preevent levels for one year. The contradictions between previous studies and this study potentially originate from the importance of the territories. 相似文献

The current study investigated the effects of trait worry, a subcomponent of trait anxiety, on the process of updating information in working memory (WM). A leading theory on anxiety and executive functions, attentional control theory (ACT), states that anxiety is not related to WM updating in emotionally neutral situations. Previous research, however, has focused almost exclusively on WM span tasks that primarily emphasised storage, rather than the updating of WM representations. Moreover, few studies have directly examined the effects of trait worry. In this study, 116 subjects performed a WM updating task that required the memorisation of short lists of words and the within-trial removal of some of these items from WM. Results indicated that levels of trait worry were not related to word-span performance, but were related to performance on trials that required subjects to effectively update WM. Moreover, these effects were observed only for trait worry, not for levels of anxious arousal or comorbid levels of dysphoria. These results support the hypothesis that trait worry is related to WM updating performance and thereby extend ACT in new directions. 相似文献

Attention problems (behavior problems including inattention, disorganization, impulsivity, and hyperactivity) are widely thought to reflect deficits in executive functions (EFs). However, it is unclear whether attention problems differentially relate to distinct EFs and how developmental stability and change predict levels of EFs in late adolescence. We investigated, in an unselected sample, how teacher-rated attention problems from ages 7 to 14 years related to three correlated but separable EFs, measured as latent variables at age 17. Attention problems at all ages significantly predicted later levels of response inhibition and working memory updating, and to some extent set shifting; the relation to inhibiting was stronger than the relations to the other EFs or IQ. Growth models indicated that attention problems were quite stable in this age range, and it was the initial levels of problems, rather than their changes across time, that predicted later EFs. These results support the hypothesis that attention problems primarily reflect difficulties with response inhibition. 相似文献

Studies on the prevention of antisocial behavior in neighborhoods through efficacious social control have focused on collective efficacy as the theoretical mechanism by which children at the community level can be successfully socialized to develop an aversion to antisocial behaviors. We hypothesized that the effect of collective efficacy within communities on antisocial behaviors could be mediated by social-information-processing biases and tested the generality of these mediation effects for undergraduates (N = 929) in Japan, China, South Korea, and the United States, countries with widely varying cultures and political systems. Structural equation modeling revealed that the effects of collective efficacy on antisocial behaviors were perfectly mediated by social-information-processing biases. Findings also confirmed the generality of these mediational effects in all four countries investigated. 相似文献
