To what extent do adolescents and their friends socialize each others’ attitudes toward immigrants? Can friends’ positive attitudes toward immigrants counter adolescents’ negative attitudes toward immigrants, and do friends’ negative attitudes decrease adolescents’ positive attitudes? These questions were examined by following a large (N?=?1,472) friendship network of adolescents (49.2 % girls; M age?=?13.31 at first measurement) across three annual measurements. Selection and influence processes regarding tolerance and xenophobia were distinguished with longitudinal social network analyses, controlling for effects of age, gender, and immigrant background. Findings showed that friends’ tolerance predicted increases in adolescents’ tolerance and friends’ xenophobia predicted increases in adolescents’ xenophobia. Moreover, friends’ tolerance predicted a lower likelihood of adolescents’ xenophobia increasing. The current results suggest that interventions should distinguish between tolerance and xenophobia, as these appear to represent two separate dimensions that are each influenced in specific ways by friends’ tolerance and xenophobia.  相似文献

In this paper, Bion's different theories on the development of thinking will be introduced: on the one hand, his theory of thoughts as resulting from tolerance for the absence of the object, and on the other hand, dream thoughts and thoughts as resulting from the presence of the object, originally through the mother's containing function. The effects of failures in this development will be discussed; among other things, a hypertrophy of the apparatus of projective identification at the expense of thinking capacities. Briefly, a comparison will be made between a facilitating relation between container and contained and the oscillation between the paranoid-schizoid and depressive position, which Bion describes as a prerequisite for open symbolizing processes. Bion's theories and concepts will be supplemented by Winnicott's theories on the “creative illusion” and the breast/the mother as a “subjective object” as a precondition for the symbolizing capacity that later develops in the “potential space”. Very briefly, a comparison is made between Winnicott's term “the subjective object” and Segal's term “symbolic equation”. Clinical vignettes are interpolated.  相似文献

Abstract

The relationship between healthy lifestyle and personality and attitudinal variables was analyzed with data collected from 809 men and 996 women aged 18–30 years in England, Belgium, Finland and Norway as part of the European Health and Behaviour Survey. A health practices index was constructed on the basis of performance of sixteen behaviours including smoking, alcohol consumption, exercise, sleep time and a variety of dietary and preventive practices. Scores on the health practices index were higher in women than men, but in both sexes the index was normally distributed. Consistently healthy practices were positively correlated with extraversion and optimism, and negatively associated with neuroticism, psychoticism and chance locus of control beliefs. These effects were maintained after controlling for social desirability, but together accounted for only a modest proportion of the variance in the health practices index. The results are discussed in relation to the factors characterising health conscious and unhealthy lifestyles.  相似文献

ObjectiveThe present study examined to what extent off-field offside decision-making training transfers to real-life offside situations.Design/methodsEighteen Belgian assistant referees were included in the experiment. Ten assistant referees (i.e., training group) were exposed to a pre- and posttest and, in between, four off-field offside training sessions via a web-based training protocol. The remaining eight assistant referees participated in the control group and only completed the pre- and posttest. During both test sessions, which were conducted separately for each group, both an on- and off-field offside decision-making test was completed.ResultsFirst, an increase in response accuracy and a decrease in flag errors were observed for the training group from pre- to posttest in both the on- and off-field offside test. Second, only the training group improved in the recall and recognition accuracy of the position of the receiving attacker at the moment of the pass.ConclusionsThis study demonstrates that perceptual-cognitive skill training results in a positive and direct transfer to on-field offside decisions. Therefore, the structure and the content of the current training intervention mimics the perceptual difficulties of real-match situations and can help the assistant referees to mediate and enhance their offside decision-making skills, both on- and off-field.  相似文献

This report presents results from a study of the dimensionality and longitudinal stability of some common self-reported somatic complaints in teenage girls. Data were supplied by the Swedish longitudinal research program “Individual Development and Adaptation”. At four age levels (age 10, 13, 15, and 16 years) a representative sample of approximately 500 girls filled out questionnaires on various adjustment problems, including some typical somatic complaints. A separate dimension of somatic complaints was identified at each age level through factor analysis of the questionnaire data. Correlational stability of somatic complaints was not high until middle adolescence. At this age fairly stable patterns of somatic complaints were also found at the individual level; different somatic complaints were not found to be interchangeable. The results support the interpretation of girls' somatic complaints as a single, meaningful dimension in late childhood and adolescence. This dimension may be hypothesized to constitute a psychological process, somatization, manifesting itself in fairly stable patterns at the individual level in middle adolescence.  相似文献

Abstract

The current pilot study aimed at providing an initial assessment of how anxiety influences police officers’ shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartridges. Measurements included shooting accuracy, movement times, head/body orientation, and blink behavior. Results showed that under HA, shooting accuracy decreased. Underlying this degradation of performance, participants acted faster and made themselves smaller to reduce the chance of being hit. Furthermore, they blinked more often, leading to increases in the amount of time participants had their eyes closed. Findings provide support for attentional control theory, hereby also pointing to possible interventions to improve police officers’ shooting performance under pressure.  相似文献

Over the last few decades, increased flexibility and lack of stability in employment has made job insecurity a work stressor that affects more and more employees. Since worrying about potential job loss (quantitative job insecurity) or possible loss of valued job features (qualitative job insecurity) constitutes a subjective perception, it has been claimed that personality factors may be decisive for job insecurity perceptions. Furthermore, the perception of a stressor, in this case job insecurity, could be argued to be dependent on appraisals of available coping resources. This study investigates whether core self-evaluations predict job insecurity perceptions, and whether coping mediates this relationship, in a two-wave data set from a Swedish sample of white-collar workers (N = 425). The results show that core self-evaluations had a negative total effect on both qualitative and quantitative job insecurity. Core self-evaluations were positively related to problem-focused coping but not to emotion-focused coping. However, there was no mediating effect of coping style on the association between core self-evaluations and job insecurity.  相似文献

Perceived job autonomy has been recognized as a central tenet of work design, leading to a range of positive outcomes. Still, scholars have rightfully questioned its predictive role for several outcomes, including turnover intention as the two have been found to be virtually unrelated. In line with calls for more complex research on the predictive role of perceived job autonomy on employee outcomes, the purpose of this study was to investigate whether the relationship between perceived job autonomy and turnover intention may be prone to contextual influences. Two cross-sectional surveys among 680 Norwegian employees from different public service organizations showed that the relationship between perceived job autonomy and turnover intention was moderated by perceived supervisor support. In support of our hypothesis, the form of the moderations revealed that perceived job autonomy was negatively related to turnover intention only for employees reporting high levels of perceived supervisor support. Implications for practice and directions for future research are discussed.  相似文献
