The purpose of this study was to examine the effects of exposure to political violence on preschool children and their mothers. We explored whether these dyads are different from dyads with no known history of exposure to violence and from mother–child dyads with known exposure to domestic violence. Specifically, we explored differences in mothers' psychological status (depression and anxiety), dyadic emotional availability (EA), children's social information processing, and children's social behaviour, in a sample of 216 dyads divided into three groups (exposure to political violence, no exposure to violence, and exposure to domestic violence). We found evidence to support our hypotheses that children exposed to domestic violence exhibit the highest levels of social maladjustment with smaller but still significant differences between children exposed to political violence and children in the comparison group. As expected, the lowest EA scores were found in the exposure to domestic violence group, followed by dyads in the exposure to political violence group. Dyads belonging to the comparison group (no exposure) exhibited the highest levels of EA. These findings contribute to our understanding of the meaning of exposure to political violence, as well as sharpen the difference between exposure to political and domestic violence. 相似文献
Ample research has demonstrated the benefits of basic autonomy supportive practices (e.g., perspective-taking, choice, minimizing-control) for adolescents’ psychosocial functioning. Herein, we posit that there is one additional autonomy supportive practice with specific importance for adolescents’ development: Reflective Authentic Inner Compass facilitation. This practice is posited to contribute to the formation of an Authentic Inner-Compass: An action-guiding schema, informing youth on what they truly value, need, and want, and consisting of two parts: (1) A foundation including authentic values, interests, and life-aspirations, and (2) Autonomous commitment to future-oriented goals and decisions, based on the foundation. A longitudinal study of 18–19 year-old Israeli adolescents showed that perceived Reflective Authentic Inner Compass Facilitation by instructors uniquely predicted (beyond Basic Autonomy Support) adolescents’ experience of having an authentic inner-compass in the military domain, which then predicted autonomous engagement in plan-promoting activities. A cross-sectional study with 16?18 year-old Belgian adolescents showed that perceived Reflective Authentic Inner Compass Facilitation by parents uniquely predicted (beyond Basic Autonomy Support) the experience of having an authentic inner-compass, which then related positively to well-being. Implications of the notion of the authentic inner compass for the conceptualization of autonomy support and the experience of autonomy are discussed.
Accumulated evidence from electrophysiology and neuroimaging suggests that face perception involves extrastriate visual mechanisms specialized in processing physiognomic features and building a perceptual representation that is categorically distinct and can be identified by face-recognition units. In the present experiment, we recorded event-related brain potentials in order to explore possible contextual influences on the activity of this perceptual mechanism. Subjects were first exposed to pairs of small shapes, which did not elicit any face-specific brain activity. The same stimuli, however, elicited face-specific brain activity after subjects saw them embedded in schematic faces, which probably primed the subjects to interpret the shapes as schematic eyes. No face-specific activity was observed when objects rather than faces were used to form the context. We conclude that the activity of face-specific extrastriate perceptual mechanisms can be modulated by contextual constraints that determine the significance of the visual input. 相似文献
Theories of visionary leadership propose that groups bestow leadership on exceptional group members. In contrast, social identity perspectives claim that leadership arises, in part, from a person's ability to be seen as representative of the group. Integrating these perspectives, the authors propose that effective leaders often share group members' perspectives concerning the present, yet offer a unique and compelling vision for the group's future. In addition, although intergroup contexts may increase the value of representativeness, the authors predict that vision dominates representativeness in single-group situations characterized by high levels of collective stress (e.g., a natural disaster). Five studies demonstrated that visionary leaders (those who offer novel solutions to their group's predicament) attract more followers, promote group identification and intrinsic motivation, mobilize collective action, and effectively regulate group members' emotions and reactions to crises compared to representative leaders. The authors discuss when, why, and how vision triumphs over representativeness in leader emergence and effectiveness. 相似文献
The present study examined the role of alerting in modulating attentional bias to salient events. In a global/local processing task, participants were presented with a large arrow (global level) comprised of smaller arrows (local level) pointing in the same or opposite directions and had to indicate the direction of the large or small arrows in different blocks. Saliency of the global and local levels was manipulated, creating global-salient and local-salient conditions. Alerting signals were presented in half of the trials prior to the target. Results revealed a double dissociation in the effects of alerting on global/local interference effects. In a global salient condition, alerting increased global interference and decreased local interference. In a local salient condition, alerting reduced global interference and increased local interference. We demonstrate that within a single task, alerting can increase and reduce conflict based on perceptual saliency. These findings help to better understand disorders like hemispatial neglect in which both arousal and attention to salient events are impaired. These results also challenge previous theories suggesting that alerting acts to increase conflict interference. We argue that alerting is an adaptive mechanism that diverts attention to salient events, but comes at a cost when selective attention to less salient details is required. 相似文献
The paper proposes a novel solution to the problem of the time of a killing (ToK), which persistently besets theories of act-individuation. The solution proposed claims to expose a crucial wrong-headed assumption in the debate, according to which ToK is essentially a problem of locating some event that corresponds to the killing. The alternative proposal put forward here turns on recognizing a separate category of dynamic occurrents, viz. processes. The paper does not aim to mount a comprehensive defence of process ontology, relying instead on extant defences. The primary aim is rather to put process ontology to work in diagnosing the current state of play over ToK, and indeed in solving it. 相似文献
How do leaders generate a learning climate that yields favorable organizational outcomes? To address this question, we offer and test a model linking charismatic leadership with the team‐emergent states of shared vision and trust within the team, as predicting organizational learning climate, and long‐term assessments of organizational outcomes by key stakeholders. We examined this model in a sample of 69 Arab elementary schools in Israel using multiple sources of raters, predicting long‐term assessments by key stakeholders of respective schools (parents and superintendents) at 2 points in time: 1 year and 3 years following the survey of the teachers. In line with our expectations, we obtained an overall, indirect effect between charismatic leadership and organizational learning climate. We also found support for both the direct and indirect effects of leader charisma through trust within the team on organizational learning climate and school outcomes. Although charismatic leadership predicted shared vision among team members, shared vision did not predict organizational learning climate, and hence, our proposed mediating effects of shared vision on organizational learning climate and outcomes were not supported. We discuss both theoretical and practical implications for the effects of leaders on learning processes and outcomes. 相似文献
This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to synaesthetes experiencing taste and to control participants lacking any synaesthetic experience. This suggests that the presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Number forms are equally common in men and women, unlike previous reports of synaesthesia that have suggested a strong female bias. Individuals who possess a number form are also likely to possess visuo-spatial forms for other ordinal sequences (e.g. days, months, letters) which suggests that it is the ordinal nature of numbers rather than numerical quantity that gives rise to this particular mode of representation. Finally, we also describe some consequences of number forms for performance in a number comparison task. 相似文献
