This paper describes and discusses the ancient superstition of the Evil Eye. The author describes his own personal childhood introduction to the subject of the Evil Eye which years later instigated his scholarly inquiry. The history of this very geographically widespread folk belief is elaborated upon, along with common manifestations as they appear in a number of different countries and cultures. Some of the methods used to thwart the negative effects of the Evil Eye are enumerated. Relevant psychodynamics and common expressions of the Evil Eye superstition are elucidated upon.  相似文献

The coincidence of historical trends in youth antisocial behavior and change in family demographics has led to speculation of a causal link, possibly mediated by declining quality of parenting and parent–child relationships. No study to date has directly assessed whether and how parenting and parent–child relationships have changed. Two national samples of English adolescents aged 16–17 years in 1986 (N = 4,524 adolescents, 7,120 parents) and 2006 (N = 716 adolescents, 734 parents) were compared using identical questionnaire assessments. Youth-reported parental monitoring, expectations, and parent–child quality time increased between 1986 and 2006. Ratings of parental interest did not change. Parenting differences between affluent and disadvantaged families narrowed over time. There was thus little evidence of a decline in quality of parenting for the population as a whole or for disadvantaged subgroups. Parent-reported youth conduct problems showed a modest increase between 1986 and 2006. Findings suggested that the increase in youth conduct problems was largely unrelated to observed change in parent–child relationships.  相似文献

This study looked at cumulative lifetime estrogen exposure, as estimated with a mathematical index (Index of Cumulative Estrogen Exposure (ICEE)) that included variables (length of time on estrogen therapy, age at menarche and menopause, postmenopausal body mass index, time since menopause, nulliparity and duration of breastfeeding) known to influence estrogen levels across the life span, and performance on prospective and retrospective memory measures in a group of 50 postmenopausal women (mean age=69.3years) who, if they were current or former users of estrogen therapy, had started therapy within 5years of menopause. The ICEE was found to be a significant predictor of performance on the Prospective Memory task (F(1)=4.21, p=.046, η(p)(2)=.084). No significant relationship was noted between the ICEE and performance on measures of retrospective memory. The results suggest that the level of cumulative lifetime exposure to estrogen a woman has influences her prospective memory performance later in life and that the influence of reproductive and biological markers of endogenous estrogen exposure are relevant factors to consider when studying the effect of estrogen therapy on cognitive functioning in postmenopausal women. In addition, the finding that performance on a measure of prospective memory, but not performance on measures of retrospective memory, was associated with the ICEE adds further support to the theory that the frontal cortex may be especially sensitive to estrogen.  相似文献

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.  相似文献

The role of physical and relational aggression in adolescents' friendship selection was examined in a longitudinal sample of 274 Chilean students from 5th and 6th grade followed over 1 year. Longitudinal social network modeling (SIENA) was used to study selection processes for aggression while influence processes were controlled for. Furthermore, the effects of network characteristics (i.e., reciprocity and transitivity), gender, and social status on friendship selection were examined. The starting assumption of this study was that selection effects based on aggression might have been overestimated in previous research as a result of failing to consider influence processes and alternative characteristics that steer friendship formation. The results show that selection effects of both physical and relational aggression disappeared when network effects, gender, and social status were taken into account. Particularly gender and perceived popularity appeared to be far more important determinants of friendship selection over time than aggression. Moreover, a peer influence effect was only found for relational aggression, and not for physical aggression. These findings suggest that similarity in aggression among befriended adolescents can be considered to be mainly a by-product rather than a leading dimension in friendship selection.  相似文献

We explored and compared rates of youth diagnosed with oppositional defiant disorder (ODD) at entry into three broad program types, home-based care, foster care, and residential care. We also explored factors other than an ODD diagnosis that could be associated with program placement, and compared the presence of these factors in youth with and without an ODD diagnosis. Analyses were conducted using data from an ongoing, private-agency led, outcome measurement project. Programs were grouped into low (home-based), moderate (foster), or high (residential) categories, based upon levels of supervision and structure provided. A sample of 9,564 youth admitted into care between years 2005 and 2007 was used. Results suggested the following rates of ODD: 14.2 % overall; 7.9 % for low level programs; 5.3 % for moderate level programs; 21.1 % for high level programs. Rates were significantly different by program level (p ≤ 0.001). Sixty of 65 additional risk factors were also significantly associated with placement by level of program. No risk factors were unique to youth with ODD. Of the significant factors for youth with ODD, 4 were particularly strong: Classification as a child in need of services (CHINS), history of neglect, verbal aggression, and truancy. Youth classified as CHINS and with substantiated or suspected neglect were more likely placed into a moderate level program. Youth with verbal aggression or truancy were more likely placed into a high level program. Results suggested many factors are considered at program entry. Given the potential for poor prognosis and social costs of ODD, results support an individualized approach to placement determinations, with increased attention to symptoms of ODD and associated features at program entry.  相似文献

Three main ideological stances exist regarding sex work issues: abolitionism, sex-positive feminism, and decriminalization. We argue for decriminalization based on decades of research results. Research on female sex workers is most often done through feminist theory and focus on gender relationships and on the experience of oppression and/or agency. Such studies examine the motivations to do sex work, the experience of being objectified, the stigma related to sex work, and, finally, the impact of this kind of work on self-esteem, on couple relationships, and on social relationships. Research on male sex workers examines power dynamics, representations of masculinity, self-perception, and the socioeconomic conditions that lead to sex work and influence safe-sex practices. Usually, feminist approaches do not take the experiences of male sex workers into account. However, taking these experiences into consideration would give a broader perspective to the understanding of sex work, as the experiences of male sex workers show many aspects similar to those of female sex workers. We contend that a woman’s sexual experience has been socially constructed as being part of her identity, in such a way that she becomes socially devalued whenever she does not comply to norms, thus making sex work a ‘degrading’ experience even though it is not intrinsically so.  相似文献

Given that early academic achievement is related to numerous developmental outcomes, understanding processes that promote early success in school is important. This study was designed to clarify how students’ (N = 291; M age in fall of kindergarten = 5.66 years, SD = 0.39 year) effortful control, relational peer victimization, and classroom participation relate to achievement, as students progress from kindergarten to first grade. Effortful control and achievement were assessed in kindergarten, classroom participation and relational peer victimization were assessed in the fall of first grade, and achievement was reassessed in the spring of first grade. Classroom participation, but not relational peer victimization, mediated relations between effortful control and first grade standardized and teacher-rated achievement, controlling for kindergarten achievement. Findings suggest that aspects of classroom participation, such as the ability to work independently, may be useful targets of intervention for enhancing academic achievement in young children.  相似文献

The ability to accurately assess credibility is important in countless situations, including many in which individuals being assessed are not speaking their native language. There is reason to believe that native and non‐native speakers may behave differently when lying and that detectors may have a bias to believe non‐native speakers are lying. However, very little is known about detecting deception in non‐native speakers, and the few existing studies have not resulted in consistent findings. The current research compared the ability to detect lies and truths in native speakers with that in non‐native speakers and looked at differences in the cues displayed via the Psychologically Based Credibility Assessment Tool. Results from two samples with different demographic characteristics and backgrounds indicated that there was a bias to believe that non‐native speakers were lying. These results may have implications regarding the use of interpreters in settings where credibility is being assessed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
