The effects of attention-deficit/hyperactivity disorder (ADHD) symptoms on the psychosocial functioning of Hispanic youth have been understudied. It also remains unclear if the well-established associations between ADHD symptoms and academic and social impairment are exacerbated by co-occurring internalizing symptoms. The purposes of the present study were to (1) examine whether ADHD symptoms would be associated with academic and social problems while also controlling for oppositional defiant disorder (ODD) symptoms, and (2) test the hypothesis that anxious and depressive symptoms would moderate the relations between ADHD symptoms and academic and social problems. Participants were 142 at-risk Hispanic adolescents (54 % male, ages 14–19) who reported on their anxious and depressive symptoms, as well as their teachers who reported on adolescents’ ADHD symptoms, ODD symptoms, academic problems, and social problems. When the psychopathology variables were included simultaneously in a path model, ADHD was the only domain significantly positively associated with academic problems. In contrast, ODD and depressive symptoms were the only domains significantly positively associated with social problems when all of the psychopathology variables were included in the path model. No moderation effects were found in relation to academic problems, although a significant ADHD × depression interaction was found in relation to social problems. Specifically, ADHD symptoms were not associated with social problems among adolescents who reported low levels of depressive symptoms, but the association between ADHD symptoms and social problems was significant at higher levels of depression. In addition to targeting oppositionality, attending to the combined presence of ADHD and depressive symptoms will be important for reducing the social impairments among Hispanic adolescents. 相似文献

Social identity theory and the related concept of organizational identification provide a conceptual lens to consider how and why corporate citizenship affects individual employees. The model we develop predicts that employee perceptions of corporate citizenship (PCC) indirectly affect organizational citizenship behavior (OCB) and employee deviance. Results from a sample of working adults demonstrate that PCC directly influences organizational identification, which in turn affects employee behavioral outcomes. Organizational identification was positively related to employee OCBs and negatively related to employee deviance. Furthermore, the strength of influence of organizational identification was greater for organizationally directed OCB and deviance than it was for individually directed OCB and deviance. 相似文献

How gender affects the relationship between hedonic shopping motivation and purchase intentions? 下载免费PDF全文
Five hundred and fifteen consumer responses are used to model the affect of online hedonic shopping motivation and online purchase intentions: moderated by the consumers' perceptions of their offline and online gendered behaviour. The model was applied across five product categories using confirmatory factor analysis and structural equation modelling. We conclude that there is no online‐gender effect on hedonic shopping motivation and purchase intentions. However, offline‐gendered behaviour does significantly affect hedonic shopping motivation and purchase intentions for females across all product categories. Our findings support the proposition that gender is merely a prosthetic device of the private self and is an intentional manipulation and misrepresentation of the anonymous body. Online gender is a performance that is hidden by the technological veil from the offline space and public self, without social constraints or criticisms. Research implications are discussed.

The Caster Semenya debacle touched off by the 2009 Berlin World Athletics Championships resulted finally in IOC and IAAF abandonment of sex testing, which gave way to procedures that make female competition eligibility dependent upon the level of serum testosterone, which must be below the male range or instrumentally countered by androgen resistance. We argue that the new policy is unsustainable because (i) the testosterone-performance connection it posits is uncompelling; (ii) testosterone-induced female advantage is not ipso facto unfair advantage; (iii) the new policy reflects the gender policing impulses endemic to sport as well as the broader cultural impulses to monstrify women and to doctor women who have nothing wrong with them; (iv) female–male performance disparities are not the only reason for sex-segregated sport, but co-exist with respectable cultural and practical reasons, which (v) provide a powerful case for allowing athletes to compete in the sex category congruent with their gender identity. 相似文献

The primary aim of this study was to assess the interaction between personality and acculturation variables in predicting antisocial behaviour among adolescent immigrants living in Spain. Previous studies have shown that the acculturation style referred to as separation (rejection of the host country's culture, and a strong desire to preserve the culture of the country of origin) was strongly related to antisocial behaviour among immigrants. A further aim of this study was to examine if the relationship between separation and antisocial behaviour was moderated by personality variables, in particular impulsivity, sensation-seeking, and personal competence. Self-reported data of a sample of 750 adolescent immigrants living in Galicia's and Madrid's regions (Spain) were gathered using previously validated scales. The results revealed that both separation and personality variables were significantly related to antisocial behaviour. Moreover, hierarchical regression analysis with the interaction terms entered found significant moderating effects i.e., the relationship between separation and antisocial behaviour was significantly amplified when impulsivity or sensation-seeking were high. The results underscore the need to examine the effects of personality, acculturation, and the interaction between both on antisocial behaviour among adolescent immigrants. 相似文献

To investigate the effect of semantic congruity on audiovisual target responses, participants detected a semantic concept that was embedded in a series of rapidly presented stimuli. The target concept appeared as a picture, an environmental sound, or both; and in bimodal trials, the audiovisual events were either consistent or inconsistent in their representation of a semantic concept. The results showed faster detection latencies to bimodal than to unimodal targets and a higher rate of missed targets when visual distractors were presented together with auditory targets, in comparison to auditory targets presented alone. The findings of Experiment 2 showed a cross-modal asymmetry, such that visual distractors were found to interfere with the accuracy of auditory target detection, but auditory distractors had no effect on either the speed or the accuracy of visual target detection. The biased-competition theory of attention (Desimone & Duncan Annual Review of Neuroscience 18: 1995; Duncan, Humphreys, & Ward Current Opinion in Neurobiology 7: 255–261 1997) was used to explain the findings because, when the saliency of the visual stimuli was reduced by the addition of a noise filter in Experiment 4, visual interference on auditory target detection was diminished. Additionally, the results showed faster and more accurate target detection when semantic concepts were represented in a visual rather than an auditory format. 相似文献

Informal social control is the communication of disapproval by one individual to another individual (the perpetrator) who has transgressed a social norm. The present research examined the conditions under which social control provokes moral versus angry emotions in the perpetrator. The roles of perceived deviance and the appraisal of the legitimacy of social control as predictors of these emotions were specifically considered. In two studies, participants imagined themselves in situations in which they engaged in moderately uncivil acts and then received social control (or not). Perpetrators’ perception of the deviance of their behaviour (Studies 1 and 2), and their explicit appraisals of the legitimacy of social control were measured (Study 2). Moral and angry emotions were also assessed. Social control intensified moral and particularly angry emotions, compared to situations in which deviant acts were performed, but no social control was received. In addition, perceived deviance as well as the politeness of the social control importantly influenced angry emotions through their effects on appraised legitimacy. 相似文献

Participants were trained on a temporal bisection task in which visual stimuli (a pink oval) of 400 ms and 1600 ms served as short and long standards, respectively. They were then presented comparison durations between 400 ms and 1600 ms, represented by faces expressing three emotions (anger, happiness, and sadness) and a neutral‐baseline facial expression. Relative to the neutral face, the proportion of long responses was higher, the psychophysical functions shifted to the left, and the bisection point values were lower for faces expressing any of the three emotions. These findings indicate that the duration of emotional faces was systematically overestimated compared to neural ones. Furthermore, consistent with arousal‐based models of time perception, temporal overestimation for the emotional faces increased with the duration values. It appears, therefore, that emotional faces increased the speed of the pacemaker of the internal clock. 相似文献

Affective words and faces each seem to be evaluated automatically, but it is unclear if they differ from one another in perceptual salience as measured by automaticity. The current study examined a possible hierarchy among affective stimuli using a modified photo–word Stroop task. Positive and negative words were superimposed across faces expressing positive (happy) and negative (angry, sad) emotions. Participants categorised the valence of faces and words. Across two experiments, interference effects were seen for both stimulus types. However, larger interference effects occurred during judgements of words than expressions, suggesting affective faces are processed more automatically than affective words. When the strength of positive and negative expressions is compared, angry expressions resulted in a larger interference effect than sad, and happy expressions produce interference similar to that of angry faces. The latter result contrasts with research suggesting potential threat stimuli are processed more automatically than positive stimuli. Implications are discussed. 相似文献
