In the present study, we investigate whether reading an action-word can influence subsequent visual perception of biological motion. The participant's task was to perceptually judge whether a human action identifiable in the biological motion of a point-light display embedded in a high density mask was present or not in the visual sequence, which lasted for 633 ms on average. Prior to the judgement task, participants were exposed to an abstract verb or an action verb for 500 ms, which was related to the human action according to a congruent or incongruent semantic relation. Data analysis showed that correct judgements were not affected by action verbs, whereas a facilitation effect on response time (49 ms on average) was observed when a congruent action verb primed the judgement of biological movements. In relation with the existing literature, this finding suggests that the perception, the planning and the linguistic coding of motor action are subtended by common motor representations. 相似文献

Previous fMRI studies have reported mixed evidence for the influence of selective attention on amygdala responses to emotional
stimuli, with some studies showing “automatic” emotional effects to threat-related stimuli without attention (or even without
awareness), but other studies showing a gating of amygdala activity by selective attention with no response to unattended
stimuli. We recorded intracranial local field potentials from the intact left lateral amygdala in a human patient prior to
surgery for epilepsy and tested, with a millisecond time resolution, for neural responses to fearful faces appearing at either
task-relevant or task-irrelevant locations. Our results revealed an early emotional effect in the amygdala arising prior to,
and independently of, attentional modulation. However, at a later latency, we found a significant modulation of the differential
emotional response when attention was directed toward or away from fearful faces. These results suggest separate influences
of emotion and attention on amygdala activation and may help reconcile previous discrepancies concerning the relative responsiveness
of the human amygdala to emotional and attentional factors. 相似文献

The majority of studies investigating attitudes toward animals have underscored the role of demographic and personality factors. The study of the role of general moral worldviews on attitudes toward animals represents an important complementary perspective. In the current study, we analyzed the relationship between moral utilitarianism toward humans and attitudes toward animals. In psychological and neuroscientific studies, moral utilitarianism has been shown to be related to empathy deficits. We expected that utilitarian decision making would be related to the endorsement of an instrumental representation of animals. We measured utilitarianism with the trolley problem, a hypothetical moral dilemma widely used in the psychological study of moral reasoning. A sample of 20,474 French adults answered an online survey measuring attitudes toward animals and moral decision making involving human beings. Results showed that irrespective of participants’ age and gender, there was a slight relationship between utilitarianism measured by the trolley dilemma and the endorsement of an instrumental representation of animal. Limitations and implications for future research are considered. 相似文献

This study tested the effect of interventions designed for people who do not eat yet the recommended daily fruit and vegetable intake (FVI) but have a positive intention to do so. Adults (N?=?163) aged 20-65 were randomised into four groups: implementation intentions (II group), self-efficacy (SE group), combination of II?+?SE group) and a control group receiving written information on nutrition. Study variables were measured at baseline, post-intervention and at 3-month follow-up. At follow-up, compared to the control group, FVI increased significantly in the II and II?+?SE groups (1.5 and 1.9 servings per day, respectively). Most psychosocial variables significantly increased compared to the control group, with the exception of SE for vegetable intake (VI). Moreover, at 3-month follow-up, change in FVI was mediated by changes in fruit intake (FI) intention and VI action planning. In conclusion, II interventions were efficient to increase FVI, with or without consideration for the development of SE. Thus, future studies should favour the adoption of this approach to bridge the intention-behaviour gap for FVI. 相似文献

Repetitions that are distributed over time benefit long‐term retention more than when massed. Recent research has suggested that the advantage of spacing may extend to induction learning‐‐learners were better able to identify the artists of previously unseen paintings when, during training, artists' paintings were spaced (paintings by different artists were interleaved) rather than massed (a given artist's paintings were blocked and presented consecutively). Increasing temporal spacing between paintings while maintaining a presentation sequence that was blocked by artist produced test performance no better than massed presentation (both worse than interleaved presentation) (Experiment 1). Displaying paintings by different artists simultaneously produced test performance as good as interleaved presentation and better than massed presentation (Experiment 2). Our findings argue that spacing benefits perceptual induction learning not because of increased temporal spacing per se but rather because interleaving paintings by different artists enhances discriminative contrast between the artists' styles.

We discuss preliminary findings from a study that investigated the effectiveness of a Holistic Arts-Based Group Program (HAP) for the development of resilience in children in need. The HAP teaches mindfulness using arts-based methods, and aims to teach children how to understand their feelings and develop their strengths. We assessed the effectiveness of the HAP by using comparison and control groups, and standardized measures. We hypothesized that children who participated in the HAP would have better scores on resilience and self-concept compared with children who took part in an Arts and Crafts group (the comparison group), and children who were waiting to attend the HAP (the control group). A total of 36 children participated in the study; 20 boys aged 8–13?years and 16 girls aged 8–14?years. A mixed-designed MANOVA was conducted using scores from 21 participants. We found evidence that the HAP program was beneficial for the children in that they self-reported lower emotional reactivity (a resilience measure) post-intervention. No changes were noted for perceptions of self-concept. Consideration should be given to how we can attend to young people’s needs in relevant ways as resilience is a condition of a community’s ability to provide resources as much as it is part of an individual’s capacity for growth. Programs such as the HAP can engage children in a creative and meaningful process that is enjoyable and strengths-based. 相似文献

In an effort to understand teacher-student relationships much research has investigated how teacher expectations of student performance in the classroom affect achievement growth. However, little research has focused on how teacher expectations of students?? educational attainment are formed. In this paper, we examine how students?? high school track placements affect teacher expectations regarding students?? educational attainment in the NELS data. NELS is a large, nationally representative longitudinal study from the United States of the graduating class of 1992. We focus on students with discrepant track placements to determine how different teachers evaluate the same student. Overall, for the same student, teachers in high track classes have higher college expectations than teachers in lower track classrooms. 相似文献

Finding a job has become a critical challenge to many youth. Immigrant youth, who have been a key part of the global migrants, are particularly vulnerable when entering the job market of the host country due to various structural barriers. However, in both public policy discourse and research, their labour market experience tends to be overlooked. In this paper, we report the employment experience of recently arrived immigrant youth based on an analysis of the LSIC and findings of in-depth interviews of 82 immigrant youth in four cities in Canada. Our results reveal that recently arrived immigrant youth tend to work in lower-skilled employment, experience significant delays in finding employment, have difficulties with foreign credential recognition, and have fewer means to access to job markets. 相似文献

Age of acquisition (AoA) ratings based on a 1-7 scale for 3,000 disyllabic words were obtained from 32 participants. We demonstrate that these estimates are both reliable and valid. These estimates add to those collected on monosyllabic words and are of value to researchers interested in factors that contribute to word processing. They also can be used in regression analyses on measures obtained from large databases, and can be used in conjunction with imageability ratings for the same word corpus to differentiate AoA from imageability. 相似文献

We examined whether the results of a response‐restriction analysis (RRA) could be predicted on the basis of response distribution in early sessions, when these sessions indicated interaction with multiple items. Four preschool‐aged children participated. For 3 of the 4 participants, the results from sessions conducted prior to restriction of the first item corresponded closely with results of the full RRA. 相似文献
