Many theories argue that goal striving is more intense when people have optimistic expectancies for achieving the goal and when attention is self-focused. Brehm’s motivational intensity theory, however, predicts that the intensity of motivation is only as high as necessary, so people will try harder for difficult tasks than for easy tasks, all else equal. The present experiment compared these two approaches by manipulating two levels of self-focused attention (low and high self-awareness, via a mirror) and two levels of task difficulty (easy and difficult). Effort was assessed as cardiovascular reactivity, particularly change in systolic blood pressure. Neither high self-focus nor an easy task per se caused increased effort; instead, high self-focus significantly increased systolic reactivity when the task was difficult. Effort was thus higher despite less optimistic goal expectancies, a finding that is predicted by Brehm’s motivational intensity theory but not by traditional self-regulation models.  相似文献

The vigilance-avoidance attention pattern is found in anxious adults, who initially gaze more at threatening pictures than nonanxious adults (vigilance), but subsequently gaze less at them than nonanxious adults (avoidance). The present research, using eye tracking methodology, tested whether anxious children show the same pattern. Children with separation anxiety disorder or no mental disorder viewed pairs of pictures, while the direction of their gaze was tracked. Each picture pair showed one picture of a woman separating from a child, the other picture of a woman reuniting with a child. The results supported the vigilance-avoidance model in children. Although the two groups’ gaze direction did not differ during the first second of viewing, anxious children gazed significantly more at separating (threatening) pictures than nonanxious children after a period of 1 s. But after 3 s the pattern reversed: anxious children gazed significantly less at the separating pictures than nonanxious children.  相似文献

Many experiments show that threats to attitudinal freedom create reactance, but the underlying dynamics of reactance‐based disagreement have not received much attention. The present experiments identified two paths from threats to disagreement. In one path, threats to attitudinal freedom directly motivate disagreement; in the other, negative cognitive responses mediate the threat's effect on disagreement. Two experiments demonstrated the causes and consequences of each path from threat to persuasion. When a communicator threatened freedom at the beginning of the message, unfavorable cognitive responses (counterarguing, negative perceptions of the source's credibility) fully mediated the effect of threat on disagreement. When the threat appeared at the end of the message however, threat had a direct, unmediated effect on disagreement (Experiment 1). The two paths had different consequences for sleeper effects: disagreement rooted in negative cognitive responses persisted, whereas disagreement directly motivated by the threat declined when the threat was removed (Experiment 2). Implications for reactance and for threat‐based sleeper effects are discussed. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

A Brain-Based Account of the Development of Rule Use in Childhood   总被引:3,自引:0,他引:3  
ABSTRACT— The ability to follow explicit rules improves dramatically during the course of childhood, but relatively little is known about the changes in brain structure and function that underlie this behavioral improvement. Drawing from neuroscientific studies in human adults and other animals, as well as from an emerging literature in developmental cognitive neuroscience, we propose a brain-based account of the development of rule use in childhood. This account focuses on four types of rules represented in different parts of the prefrontal cortex: simple rules for reversing stimulus–reward associations, pairs of conditional stimulus–response rules (both univalent and bivalent), and higher-order stimulus–response rules for selecting among task sets. It is hypothesized that the pattern of developmental changes in rule use reflects the different rates of development of specific regions within the prefrontal cortex.  相似文献

In this paper, I argue for an Aristotelian way of accommodating supererogation within virtue ethics by retrieving an account of moral heroism and providing a picture of different degrees of virtue. This, I claim, is the most appropriate virtue-ethical background allowing us to talk about supererogation without falling prey to several dangers. After summarizing the main attempts to deny the compatibility of virtue and supererogation, I will present some recent proposals to accommodate supererogation within virtue ethics. Next, I will argue that these proposals raise substantial worries. I will then offer an analysis of heroism and the degrees of virtue to outline my own alternative definition of supererogation in terms of heroic virtue.  相似文献

This study builds on previous findings regarding emotional intelligence among narcissists by considering the maladaptive aspects of emotional manipulation and distinguishing between grandiose and vulnerable narcissism. Trait-emotional intelligence and emotional manipulation capabilities of grandiose narcissists, vulnerable narcissists, and non-narcissists were compared. A convenience sample of 584 undergraduates from the University of Florence (Italy) with a mean age of 22.61 (SD?=?2.19) was recruited. A two-way ANOVA showed that vulnerable narcissists scored significantly lower than grandiose narcissists and non-narcissists in all the Bar-On EI dimensions, while grandiose narcissists scored higher than non-narcissists in Intrapersonal intelligence and the General Mood Bar-On scales. The two-way ANOVA also showed that both grandiose and vulnerable narcissists are prone to emotionally manipulate others in order to reach their aims.  相似文献

The aim of this study is to obtain information about drug consumption, leisure activities and knowledge of community services among Spanish-speaking immigrants to prevent drug abuse in this population. Quantitative methodology was used. The field work of this study has two phases: in the first stage (2003), a survey of social perception of drugs was administered to 147 subjects. During the second stage (2004), 610 surveys were administered. Data were analysed by bivariate analysis. Usual consumption of alcohol was 40.1%, usual consumption of tobacco was 31.3%, and usual consumption of cannabis was 3.4%. Drug users considered that the main reason for drug consumption was "to have fun" (p<.03). There is a relationship between leisure time and drug use. Family plays an important role in drug abuse prevention and preventive drug abuse programs must be adapted to this population.  相似文献

There has been a vast amount of research on the changes experienced by immigrants, but little is known about the changes experienced by host individuals. This article focuses on the role of host individuals in the networks of relations between immigrant populations and the communities from the dominant culture, as well as the changes experienced by host individuals because of their continuous contact with immigrants. This research applied a network approach to the study of the acculturation of host individuals. Two independent studies were carried out: a systematic analysis of the personal networks of Argentinean (n = 67), Ecuadorian (n = 59), Italian (n = 37) and German (n = 37) residents in Seville and Cadiz (Spain) (Study 1); and an ethnographic study with human service workers for Latin American immigrants in Boston (USA) (Study 2). With two different strategies, the role of host individuals in personal networks of foreigners in the United States and Spain was analyzed. The results show that host individuals tend to have less centrality than compatriots, showing an overall secondary role in the personal networks of immigrants. The lowest average centrality was observed in recent and temporal migrants, whereas the highest corresponded to the individuals with more time of residence in Spain. The personal networks of human service providers in the United States vary in ethnic composition and in their structural properties, and therefore shape different types of integrative bridges for immigrants.  相似文献

This is the first study to evaluate the psychometric properties of the Food Craving Questionnaire-Trait (FCQ-T), and Food Craving Questionnaire-State (FCQ-S) measures using a clinically heterogeneous sample of eating disorder patients (N = 177) recruited from seven different outpatient eating disorder treatment centers in Spain. Confirmatory factor analyses (CFAs) corroborated the factor structures of the FCQ-T and FCQ-S. The measures' scores and their factor-derived scale-scores yielded internal consistency reliability indexes that ranged from adequate to excellent. The measures were predictive of eating disorder symptoms. As expected, the FCQ-T was more strongly associated with eating disorder psychopathology than the FCQ-S. The results replicated the psychometric properties of the FCQ-T and FCQ-S in eating disorder populations and could become useful tools in clinical and research settings.  相似文献

The main and interactive effects of parental behavioral control and parental support on adolescent adjustment were examined with students ages 15-19 in Italy (N = 391, 59.1% male) and The Netherlands (N = 373, 45.3% male). In general, parental support was associated with better adjustment and parental control was associated with worse adjustment. However, parental control as well as age and sex moderated the effects of parental support on psychological discomfort and expectations of future success. Positive self-perceptions were less well predicted. Further, there were more moderated effects in the Dutch sample than in the Italian sample. Generalizability of the contributions of parenting behavior to adolescent adjustment outside of a North American context is discussed.  相似文献
