Arguments about the existence of language-specific neural systems and specifically about the independence of syntactic and semantic processing have focused on the event-related brain measures (ERPs) as tool to monitoring moment-by-moment the cognitive processes underlaid. In the present experiments, the available evidence indicates that the ERP response to semantic anomalies is at least partially distinct from the ERP response to syntactic anomalies and that two distinct processes are activated in sentences comprehension. ERPs were recorded from 10 electrodes while subjects read (Experiment 1) or listened (Experiment 2) to sentences containing semantic or syntactic violations. Final-words that were inconsistent with the sentence context elicited a negative-going wave at about 400 ms poststimulus, whereas penultimate-word incongruous with the grammatical structure (subject–verb non-agreement) elicited a positive-going wave about 600 ms poststimulus. No differences based on the perceptual modality of the stimulus (visual or auditory) nor different ERP correlates as a function of task-relevance (explicit/implicit task induction) were found. The implications of our results for Italian language are explained. 相似文献

Two studies employing a mixed experimental design were conducted to determine if perceptions of bullying, attitudes towards victims, and students' sense of safety at school were influenced by bystanders' reactions to different types of bullying. In Study 1, 217 middle-school children were randomly assigned to read a hypothetical scenario describing a direct bullying episode. In Study 2, 376 primary-school children and 390 middle-school children were presented with scenarios describing a direct bullying episode and an indirect bullying episode. In all scenarios, the bystanders' reactions to the bullying and the gender of the victim were manipulated. Participants endorsed the prosocial behavior in favor of the victims and did not endorse pro-bullying behavior. Furthermore, they perceived passive reactions to the bullying as negative behavior. Participants showed positive attitudes towards victims, which were significantly higher at younger grade levels and among girls. Bystanders' behavior influenced both participants' perceptions of the victims and their perceived sense of safety at school. Implications for anti-bullying programs based upon the group ecology are discussed. 相似文献

Previous studies have revealed that decoding of facial expressions is a specific component of face comprehension and that semantic information might be processed separately from the basic stage of face perception. In order to explore event-related potentials (ERPs) related to recognition of facial expressions and the effect of the semantic content of the stimulus, we analyzed 20 normal subjects. Faces with three prototypical emotional expressions (fear, happiness, and sadness) and with three morphed expressions were presented in random order. The neutral stimuli represented the control condition. Whereas ERP profiles were similar with respect to an early negative ERP (N170), differences in peak amplitude were observed later between incongruous (morphed) expressions and congruous (prototypical) ones. In fact, the results demonstrated that the emotional morphed faces elicited a negative peak at about 360 ms, mainly distributed over the posterior site. The electrophysiological activity observed may represent a specific cognitive process underlying decoding of facial expressions in case of semantic anomaly detection. The evidence is in favor of the similarity of this negative deflection with the N400 ERP effect elicited in linguistic tasks. A domain-specific semantic module is proposed to explain these results. 相似文献

This study examined the role of pro-victim attitudes, personal responsibility, coping responses to observations of bullying,
and perceived peer normative pressure in explaining defending the victim and passive bystanding behavior in bullying. A total
of 462 Italian early adolescents (mean age = 13.4 years, SD = 9 months) participated in the study. The behaviors were measured
through two informants: each individual student and the teachers. The findings of a series of hierarchical regressions showed
that, regardless of the informant, problem solving coping strategies and perceived peer normative pressure for intervention
were positively associated with active help towards a bullied peer and negatively related to passivity. In contrast, distancing
strategies were positively associated with passive bystanding, whereas they were negatively associated with teacher-reported
defending behavior. Moreover, self-reported defending behavior was positively associated with personal responsibility for
intervention, but only under conditions of low perceived peer pressure. Finally, the perception of peer pressure for intervention
buffered the negative influence of distancing on passive bystanding tendencies. Future directions are discussed. 相似文献

This study analyzed the relations of two dimensions of moral cognition (i.e., acceptance of moral transgression and moral disengagement) and two forms of status in the peer group (i.e., social preference and perceived popularity) with bullying and defending among 235 primary‐school children and 305 middle‐school early adolescents. Social status was tested as a moderator of the associations between moral cognition and bullying and defending. Participants completed self‐reports assessing the two dimensions of moral cognition and peer nominations for status, bullying, and defending. Both acceptance of moral transgression and moral disengagement were associated to bullying among early adolescents only, whereas in childhood moral disengagement was linked to defending among girls. Social status moderated the associations between morality dimensions and bullying and defending. The moderating effects of status were discussed considering status as a magnifying lens for the relations between individual characteristics and social behavior. The results were also discussed with reference to age and gender differences in the associations. Aggr. Behav. 38:456‐468, 2012. © 2012 Wiley Periodicals, Inc. 相似文献

A cross‐sectional study from a sample of 663 elementary school children assessed the four sets of moral disengagement mechanisms conceptualized by Bandura (i.e., cognitive restructuring, minimizing one's agentive role, disregarding/distorting the consequences, blaming/dehumanizing the victim) at both the individual and the class level. Additionally, an analysis of the relations of these mechanisms to pro‐bullying behavior was conducted. Multilevel analysis showed a significant relationship between cognitive restructuring and individual pro‐bullying behavior. Moreover, between‐class variability of pro‐bullying behavior was positively related to minimizing one's agentive role and blaming/dehumanizing the victim at the class level. Conversely, class disregarding/distorting the consequences was negatively associated with between‐class variation in the outcome behavior. Implications for understanding the role of morality in children's bullying are discussed. Aggr. Behav. 38:378‐388, 2012. © 2012 Wiley Periodicals, Inc. 相似文献

The aim of the present study was to explore the association between gender role, in terms of self-attribution of masculine and feminine characteristics, and children's involvement in bullying problems during the elementary-school years. A total of 113, six- to ten-year-old children completed self-report measures of bullying and victimization and a masculinity–femininity scale. Their teachers provided ratings of pupils’ reactive and proactive aggressive behavior. Data from a hierarchical regression on bullying scores showed that, irrespective of sex, masculine traits predicted active bullying behavior. Moreover, bullying was also related to victimization and to teacher's evaluation of reactive aggression. Our findings suggest the need for longitudinal and cross-cultural studies in this line of research. 相似文献
