Using the mismatch negativity (MMN) response, we examined how Standard French and Southern French speakers access the meaning of words ending in /e/ or /ε/ vowels which are contrastive in Standard French but not in Southern French. In Standard French speakers, there was a significant difference in the amplitude of the brain response after the deviant-minus-standard subtraction between the frontocentral (FC) and right lateral (RL) recording sites for the final-/ε/ word but not the final-/e/ word. In contrast, the difference in the amplitude of the brain response between the FC and RL recording sites did not significantly vary as a function of the word’s final vowel in Southern French speakers. Our findings provide evidence that access to lexical meaning in spoken word recognition depends on the speaker’s native regional accent. 相似文献

The present study reports two experiments in which a total of 20 participants without prior flight experience practiced the final approach phase in a fixed-base simulator. All participants received self-controlled concurrent feedback during 180 practice trials. Experiment 1 shows that participants learn more quickly under variable practice conditions than under constant practice conditions. This finding is attributed to the education of attention to the more useful informational variables: Variability of practice reduces the usefulness of initially used informational variables, which leads to a quicker change in variable use, and hence to a larger improvement in performance. In the practice phase of Experiment 2 variability was selectively applied to some experimental factors but not to others. Participants tended to converge toward the variables that were useful in the specific conditions that they encountered during practice. This indicates that an explanation for variability of practice effects in terms of the education of attention is a useful alternative to traditional explanations based on the notion of the generalized motor program and to explanations based on the notions of noise and local minima. 相似文献

Apraxic agraphia is a writing disorder due to a loss or lack of access to motor engrams that program the movements necessary to produce letters. Clinical and functional neuroimaging studies have demonstrated that the neural network responsible for writing includes the superior parietal region and the dorsolateral and medial premotor cortex. Recent studies of two cases with atypical lesion localisations in the left thalamus and the right cerebellum support the hypothesis that the written language network is larger than previously assumed. The aim of this study is twofold: (1) to provide a survey of cases of apraxic agraphia published between 1973 and June 2010, and (2) to provide further evidence for a role of the cerebellum in writing via three additional cases who presented with apraxic agraphia after ischemic damage in the cerebellum. Functional neuroimaging studies by means of brain perfusion SPECT showed perfusional deficits in the anatomoclinically suspected supratentorial areas, subserving language dynamics, syntax, naming, writing and executive functioning. 相似文献

People use spatial distance to talk and think about differences between concepts, and it has been argued that using space to think about different categories provides a scaffold for the categorization process. In the current study, we investigated the possibility that the distance between response keys can influence categorization times in binary classification tasks. In line with the hypothesis that distance between response keys can facilitate response selection in a key-press version of the Stroop task, our results showed that responses on incongruent Stroop trials were significantly facilitated when participants performed the Stroop task with response keys located far apart, compared with when they performed the task with response keys located close together. These results support the idea that the spatial structuring of response options facilitates categorizations that require cognitive effort, and that people can incorporate environmental structures such as spatial distance in their thought processes. Keeping your hands apart might actually help to keep things apart in your mind. 相似文献

Although it is well-established that an objectively deserved misfortune promotes schadenfreude about the misfortune, there is a small body of research suggesting that an undeserved misfortune can also enhance schadenfreude. The aim of the present study was to investigate the processes that underlie schadenfreude about an undeserved misfortune. Participants (N?=?61) were asked to respond to a scenario in which a person was responsible or not responsible for a negative action. In the responsible condition, two independent routes to schadenfreude were observed: deservingness of the misfortune (traditional route) and resentment towards the target. More importantly, results showed that when the target of the misfortune was not responsible for the negative action, the relationship between schadenfreude and resentment towards the target was mediated by the re-construal of an objectively undeserved misfortune as a ‘deserved’ misfortune. The study further found that expressing schadenfreude about another’s misfortune makes one feel better about oneself without affecting moral emotions. The findings expand our understanding of schadenfreude about undeserved negative outcomes. 相似文献

In this study, we used a paradigm similar to the one used by Milgram in his classic obedience study, using an immersive video environment. We manipulated the victim's degree of visibility and his ethnicity. When the victim was hidden, the level of obedience we obtained was similar to Milgram's. Replicating previous findings observed in real environments, participants were more obedient when the victim was hidden than when he was visible, and the more obedient participants negated their own responsibility by projecting responsibility on both the victim and the experimenter. State‐anger and right‐wing authoritarianism (RWA) emerged as two significant predictors of the level of obedience. Illustrating an underlying process of racial‐dehumanization, participants reported less anxiety and distress when the victim was a North African than when the victim was of the same racial origin as the participant. These results underscore the usefulness of using immersive environments when studying extreme social behaviors. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The ability to assess genetic ties is critical to defining one's own family and, in a broader context, to understanding relationships in groups of strangers. To recognize younger siblings as such, human firstborns can rely on the perinatal association of the mother with her new baby. Later-borns, who cannot rely on such an association, will by necessity actuate alternate strategies, such as recognition of facial clues set aside by firstborns. The effects of such differential early experiences deserve consideration; the development of matching abilities may be used throughout an individual's lifetime to detect other kinship types outside the family. In simple cognitive tasks based on matching face pictures, later-borns surpassed firstborns in detecting kinship among strangers; this pattern was found in populations of different ages and in two countries. This birth-order effect contrasts with the traditional cognitive advantage of firstborns. Inclusive fitness theory explains how early life history promotes specific strategies that can, in turn, permanently enhance human performance in certain domains. 相似文献

Expanding our knowledge on parenting practices of immigrant families is crucial for designing culturally sensitive parenting
intervention programs in countries with high immigration rates. We investigated differences in patterns of parenting between
second-generation immigrant and native families with young children. Authoritarian and authoritative control and sensitivity
of second-generation Turkish immigrant mothers of 2-year-old children (n = 70) and native Dutch mothers (n = 70) were observed in the home and in the laboratory. Controlling for maternal age and education, Turkish immigrant mothers
were less supportive, gave less clear instructions to their children, were more intrusive and were less authoritative in their
control strategies than native Dutch mothers. No differences were found in authoritarian control. In both ethnic groups supportive
presence, clarity of instruction, authoritative control, and low intrusiveness loaded on one factor. No differences between
ethnic groups were found in gender-differentiated parenting. Maternal emotional connectedness to the Turkish culture was associated
with less authoritative control, whereas more use of the Turkish language was related to more sensitivity. Even though mean
level differences in parenting behaviors still exist between second-generation Turkish immigrant and native Dutch mothers,
the patterns of associations between parenting behaviors were comparable for both groups. This suggests that existing parenting
interventions for native families may be applicable to second-generation Turkish immigrants as well. 相似文献

The executive processes are well known to decline with age, and similar data also exists for attentional capacities and processing speed. Therefore, we investigated whether these two last nonexecutive variables would mediate the effect of age on executive functions (inhibition, shifting, updating, and dual-task coordination). We administered a large battery of executive, attentional and processing speed tasks to 104 young and 71 older people, and we performed mediation analyses with variables showing a significant age effect. All executive and processing speed measures showed age-related effects while only the visual scanning task performance (selective attention) was explained by age when controlled for gender and educational level. Regarding mediation analyses, visual scanning partially mediated the age effect on updating while processing speed partially mediated the age effect on shifting, updating and dual-task coordination. In a more exploratory way, inhibition was also found to partially mediate the effect of age on the three other executive functions. Attention did not greatly influence executive functioning in aging while, in agreement with the literature, processing speed seems to be a major mediator of the age effect on these processes. Interestingly, the global pattern of results seems also to indicate an influence of inhibition but further studies are needed to confirm the role of that variable as a mediator and its relative importance by comparison with processing speed. 相似文献
