Interactions between sentence context and word frequencyinevent-related brainpotentials 总被引:2,自引:0,他引:2
Event-related brain potentials (ERPs) were recorded as subjects silently read a set of unrelated sentences. The ERP responses elicited by open-class words were sorted according to word frequency and the ordinal position of the eliciting word within its sentence. We observed a strong inverse correlation between sentence position and the amplitude of the N400 component of the ERP. In addition, we found that less frequent words were associated with larger N400s than were more frequent words, but only if the eliciting words occurred early in their respective sentences. We take this interaction between sentence position and word frequency as evidence that frequency does not play a mandatory role in word recognition, but can be superseded by the contextual constraint provided by a sentence. 相似文献

The study followed-up 245 patients referred to the Henderson Hospital (194 admitted for treatment and 51 not admitted) and for whom information had been collected on their social background and certain psychological variables allowing a classification and typology of personality disorder to be worked out. The study indicates that the therapeutic community treatment is effective with selected individuals showing the antisocial behaviour associated with such disorder. In particular this treatment is of benefit to the offenders with only one conviction and who are able to persevere with treatment for a period of 6 months for treatment to be maximally effective. The variation of psychological types within the broad category of personality disorder was demonstrated and this has a bearing on the outcome of treatment, the extrapunitive neurotic being of poorest prognosis with or without treatment. Yet even in this group, therapeutic community treatment can be effective. 相似文献

Recent visual evoked potential (VEP) studies suggest that during sustained voluntary attention, irrelevant or unattended visual stimuli may be filtered precortically. Testing of this hypothesis in humans requires knowledge of the origin of specific components of the VEP that are affected by selective attention. This study describes techniques and procedures for distinguishing between retinal and nonretinal components of VEPs recorded from electrodes placed strategically around the eyes and on the forehead. By visually stimulating one eye at a time while recording simultaneously from both, and by stimulating a given retinal area with the eyes fixated on the target at different angular deviations from the normal line of regard, components of the VEPs around the eyes can be distinguished as of retinal or nonretinal origin. The results are discussed in terms of volume conduction theory. 相似文献

Young children and adults were compared in their processing of position and form information when only one type of information was processed and when both types of information were processed. For adults, position information in both the single and combined tasks showed a linear increase in report accuracy with increasing duration. For children, this linear increase was found only in the single task, at longer durations, resulting in a loss of parity across tasks for position information among children. No loss of parity was found for form information for either age group. The children’s loss of parity in processing position information when combined with form information replicates their previously demonstrated inability to process multiple-form arrays using a parallel independent strategy. 相似文献

Event-related potentials (ERPs) were recorded from subjects as they silently read 160 different seven-word sentences, presented one word at a time. Each sentence was in itself a natural, meaningful phrase. Substantial intersubject variability was observed in the ERP waveshapes following the words. More than half of the subjects generated P3 components to word stimuli, but those who did showed similar responses to repeated control presentations of a single word. In addition, it was found that all but the first word in the sentence elicited an ERP with a significant left-greater-than-right asymmetry in the late positivity over temporo-parietal regions. The ERPs to the last words were associated with more late positivity than those to the preceding words. One quarter of the sentences, at random, ended with a word printed in a typeface that was different from that of the preceding words. This infrequent change in typeface elicited a complex ERP having three consistent late positive components. 相似文献

The effects of temporal grouping on auditory short-term memory are investigated, using pauses of different lengths to indicate the groups. No quantitative or qualitative differences were found between the shorter and longer pauses. This result, in conjunction with an analysis of the order errors, is used to suggest what kind of processing occurs during the pauses. This processing is selective, recoding the information about order according to position within a group. 相似文献

This study investigates the hypothesis that congruence in value perspectives distinguishes science-able students who persist in science from those who do not (nonpersisters). A science values measure was administered to 173 undergraduates with high levels of commitment and ability in the sciences. On each of six hypothetical dilemmas from everyday science, respondents rated the importance of three justice and three care considerations for self and for science, using a Likert-type 7-point scale. A significant three way interaction involving sex, persistence, and point of view (self/sience) emerged, with persisters generally demonstrating congruence between self and science on the value perspectives; female persisters, however, were more likely to combine justice and care perspectives than were males. Nonpersisters' self/science ratings of justice and care were sharply dissimilar, with females demonstrating the most incongruence. In all groups, justice was the prominent perspective attributed to science. 相似文献

Amyotrophic Lateral Sclerosis is a neurodegenerative disorder characterized primarily by motor network disruption. Extra-motor manifestations including executive functions, social cognition, and behavioral changes are now well recognized as important features of ALS, and are associated with frontotemporal and frontostriatal network disruption. However, the presence and characterization of language changes has received less attention. This systematic review characterizes the profile of reported language dysfunction in ALS. PRISMA guidelines were implemented to carry out and report the review. Current evidence suggests that areas of neuroanatomical disruption in ALS spread to language centers such as posterior, inferior frontal and superior temporal areas leading to deficits in word retrieval, syntactic and grammatical processing, and spelling. However, the majority of studies of language in ALS have been limited by the recruitment of small clinic-based prevalent samples and important questions remain regarding the incidence and progression of language impairment in ALS. Further studies from population-based incident cohorts will help to determine the range of language deficits in ALS, and how these relate to previously defined executive and behavioral sub-phenotypes. 相似文献

Background and objectives: This study evaluates the process and consequence of inducing self-compassion during recovery from social performance stressors. Though interest in self-compassion as an intervention target is growing, extant findings suggest that initially cultivating self-compassion can be challenging for those with high self-criticism and anxiety, common features of social anxiety disorder (SAD).Design: Quasi-experimental design.Methods: The current study evaluates the feasibility, content, and outcomes of a brief written self-compassion induction administered after consecutive laboratory social stressors, among adults with SAD (n?=?21) relative to healthy controls (HC; n?=?35).Results: Findings demonstrate the feasibility of employing a written self-compassion induction among adults with (and without) SAD, reveal group differences in written responses to the induction, and suggest that the SAD group benefitted more from the induction than the HC group, based on greater reductions in state anxiety and greater increases in self-compassion during stressor recovery. Greater use of negative affect words within written responses to the self-compassion induction, but not during general writing, predicted lower subsequent state anxiety across groups, by a medium effect size.Conclusions: Collectively, the findings support the feasibility and utility of cultivating self-compassion among adults with SAD. 相似文献
