This article explores the possible cognitive function associated with pointing gestures from a Vygotskian perspective. In Study 1, 39 children who were 2-4 years of age were observed in a solitary condition while solving a mnemonic task with or without an explicit memory demand. A discriminant analysis showed that children used noncommunicative pointing gestures only in the task with an explicit memory demand. In Study 2, 39 children who were 4-6 years of age completed an attentional task with and without the possibility of pointing. An analysis of variance showed that only those children who spontaneously pointed to solve the first task performed significantly worse in a second condition where pointing was impossible. These results suggest that besides its social interactive functions, pointing may also subserve private cognitive functions for children. 相似文献

Power increases the tendency to behave in a goal-congruent fashion. Guided by this theoretical notion, we hypothesized that elevated power would strengthen the positive association between prosocial orientation and empathic accuracy. In 3 studies with university and adult samples, prosocial orientation was more strongly associated with empathic accuracy when distinct forms of power were high than when power was low. In Study 1, a physiological indicator of prosocial orientation, respiratory sinus arrhythmia, exhibited a stronger positive association with empathic accuracy in a face-to-face interaction among dispositionally high-power individuals. In Study 2, experimentally induced prosocial orientation increased the ability to accurately judge the emotions of a stranger but only for individuals induced to feel powerful. In Study 3, a trait measure of prosocial orientation was more strongly related to scores on a standard test of empathic accuracy among employees who occupied high-power positions within an organization. Study 3 further showed a mediated relationship between prosocial orientation and career satisfaction through empathic accuracy among employees in high-power positions but not among employees in lower power positions. Discussion concentrates upon the implications of these findings for studies of prosociality, power, and social behavior. 相似文献

The purpose of this study was to examine meaning as a mediator between perceived threat and posttraumatic stress responses among a sample of 1,561 veterans who participated in war or peacekeeping operations. Data were collected by questionnaire. Path analysis was performed to assess the expected relationships between the observed variables. Meaning in terms of distrust and personal benefits partially mediated the relation between perceived threat and posttraumatic stress responses. Distrustful beliefs about others and the world were strongly associated with perceived threat, as well as intrusive and avoidant thoughts. Creating meaning in terms of a positive worldview appears to be an important mission after military deployment. 相似文献

Although emerging evidence suggests that parental behavior is related to the development of child executive functioning (EF), the mechanisms through which parenting affects child EF have yet to be investigated. The goal of this study was to examine the potential mediating role of child language in the prospective relation between maternal autonomy support and child EF. A total of 53 mother–infant dyads took part in three home visits at 15 months, 2 years, and 3 years, allowing for the assessment of maternal autonomy support (T1), child expressive vocabulary (T2), and child EF (T3). The results suggested that child language played a mediating role in the relation between maternal autonomy support and child performance on EF tasks entailing a strong impulse control component above and beyond child previous EF and family socioeconomic status (SES). In contrast, no such mediating role of language was found with EF tasks tapping mostly into working memory and set shifting. Thus, this study highlights one pathway through which parenting can affect child executive control. 相似文献

Social deficits are one of the most striking manifestations of autism spectrum disorders (ASDs). Among these social deficits, the recognition and understanding of emotional facial expressions has been widely reported to be affected in ASDs. We investigated emotional face processing in children with and without autism using event-related potentials (ERPs). High-functioning children with autism (n = 15, mean age = 10.5 ± 3.3 years) completed an implicit emotional task while visual ERPs were recorded. Two groups of typically developing children (chronological age-matched and verbal equivalent age-matched [both ns = 15, mean age = 7.7 ± 3.8 years]) also participated in this study. The early ERP responses to faces (P1 and N170) were delayed, and the P1 was smaller in children with autism than in typically developing children of the same chronological age, revealing that the first stages of emotional face processing are affected in autism. However, when matched by verbal equivalent age, only P1 amplitude remained affected in autism. Our results suggest that the emotional and facial processing difficulties in autism could start from atypicalities in visual perceptual processes involving rapid feedback to primary visual areas and subsequent holistic processing. 相似文献

Repression and sensitization as situational modes of coping with anxiety were examined as predictors of trait measures of cognitive avoidance and vigilance. In this study, 303 undergraduates saw a violent film clip to elicit anxiety. Increases in skin conductance level (SCL) and state anxiety (STA) from baseline were measured to identify repressors (high SCL, low STA) and contrast them with sensitizers (low SCL, high STA) and genuinely low anxious individuals (low SCL, low STA). State anger was also recorded. Trait measures of vigilance and cognitive avoidance were collected 2 weeks earlier. Significant SCL × STA interactions indicated that repressors scored higher on cognitive avoidance and lower on vigilance compared to sensitizers and low anxious participants. Repressors were less likely than sensitizers to report gaze avoidance during the clip. The anger by SCL interaction was nonsignificant, suggesting that repressors and sensitizers differ specifically in the processing of anxiety rather than negative affect in general. 相似文献

Relation between physical activity and academic performance in 3rd-year secondary education students

The main aim of this study was to analyze the relationship between the amount of physical activity and academic performance in 3rd-year secondary education students. The sample was taken from three secondary schools in the area of Barcelona. 284 students (158 girls, 126 boys) with an average age of 14.7 yr. participated. The International Physical Activity Questionnaire was used by students to self-report their amount of physical activity. Students' academic records were obtained for comparisons. Results showed that there was a linear relationship between academic performance and physical activity; nevertheless, there was a trend to stronger correlation when modeling the relationship between these variables with a quadratic equation. Further research should focus on whether academic performance and physical activity might be better explained with a second-order equation. 相似文献

Modulation of subjective time was examined using static images eliciting perceptions of different intensities of body movement. Undergraduate students were exposed to photographs of dancer sculptures in different dance positions for 36 sec. and asked to estimate the exposure duration. Lower movement intensities were related to shorter estimated durations. Mean durations for images of unmoving dancers were underestimated and for dancers taking a ballet step were overestimated. Temporal estimations were also related to the order of presentation of the stimuli, which suggested that subjective time estimations were influenced by the experimental context. Subjective time is related not only to the visual perception of moving images, but also of elicited perceptions of movement in static images, suggesting an embodiment effect on subjective time estimation. 相似文献

The reliability and factor structure of the Spanish version of the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ) were assessed in a sample of 213 Spanish university graduates. The questionnaire measures three types of processing preferences (verbal, object imagery, and spatial imagery). Principal components analysis with varimax rotation identified three factors, corresponding to the three scales proposed in the original version, explaining 33.1% of the overall variance. Cronbach's alphas were .72, .77, and .81 for the verbal, object imagery, and spatial imagery scales, respectively. 相似文献

We defend the view that defines the rigidity of general terms as sameness of designated universal across possible worlds from
the objection that such a characterization is incapable of distinguishing rigid from non-rigid readings of general terms and,
thus, that it trivializes the notion of rigidity. We also argue that previous attempts to offer a solution to the trivialization
problem do no succeed. 相似文献
