It has been well established that expression of conditioned fear is context independent, but the context dependency of unconditioned fear expression has rarely been explored. A recent study reported that unconditioned freezing in rats is enhanced in a familiar context, which suggests that unconditioned fear expression can be modulated by contextual processing. In order to further explore this possibility we examined unconditioned freezing in novel, familiar, and appetitive contexts; and attempted to identify brain regions critical for context-related changes in unconditioned freezing by measuring c-Fos mRNA levels in emotional circuits. Unconditioned freezing was enhanced in the appetitive context, and this enhancement was accompanied by increased c-Fos mRNA expression in the medial amygdala and hippocampus, but attenuated expression in the medial prefrontal cortex. In the appetitive context, expectation of a reward coupled with detection of threat may have enhanced unconditioned fear expression, which suggests that unconditioned fear expression can be modulated by contextual factors. Context-related expectancy mismatch may explain the enhancement of unconditioned fear expression seen in this study and warrants further examination. 相似文献

There is some evidence about the low relationship between physical prowess and cognitive function (Posthuma, Mulder, Boomsma & de Geus, 2002). The aim of this paper is to investigate the relationship between cognitive variables (spatial ability, reasoning, numerical ability, inductive reasoning, and reasoning and verbal comprehension) and physical prowess in sport performance (agility circuit, coordination circuit, horizontal jump, swimming and sprint racing). Two studies were performance. In the first one we applied a battery of standardized cognitive tests and a battery of physical grading tests to 400 subjects. When we applied factor analysis to the physical prowess and the cognitive variables, we found one general factor in cognitive variables and one general factor in physical prowess. We found a low relationship between both factors (.21). In the second study we compare the cognitive abilities in elite and amateur sport people. Results show that elite gymnastics people present higher cognitive abilities than amateur sportspeople. It should be relevant in order to clarify the total set of variables involved in sport performance. 相似文献

The objectives of this study were: (a) to examine the direct and indirect relationships among witnessing interparental violence, parenting practices, and children's long-term psychosocial adjustment; (b) to analyze the possible gender differences in the relationships specified. The sample consisted of 1295 Spanish university students (M age = 21.21, SD = 4.04). We performed statistical analyses using structural equation modeling. The results showed that witnessing parental violence as a child is related to poor long-term psychosocial adjustment during the child's adult years. Furthermore, we found that parenting practices fully mediated the relation between witnessing interparental violence and the child's long-term adjustment. The multigroup analyses showed that most of the relations among the variables did not differ significantly by gender. However, the relation between harsh discipline and antisocial behavior was stronger for males, whereas the relation between harsh discipline and depressive symptoms was stronger for females. Finally, we discuss the implications of these findings for the clinicians and specialists who plan and develop intervention programs for populations at risk. 相似文献

The central role of perceived control in the development of anxiety disorders is proposed by several theoretical models. The main objective of the present study was to examine the relation between perceived control and anxiety in Portuguese school-age children. To accomplish this objective we developed the Portuguese short form of the Anxiety Control Questionnaire for Children (ACQ-C, Weems, 2005; Pereira & Barros, 2010), whose psychometric studies are presented. The sample comprised 238 children, aged 8 to 15 years, from the general population attending Portuguese schools. Children completed measures of perceived control (ACQ-C) and their anxiety (Screen for Child Anxiety Related Emotional Disorders--Revised, SCARED-R). The psychometric studies indicate good psychometric characteristics of the Portuguese ACQ-C short form, in particular a high internal consistency (a = .85) and an adequate temporal stability (r = .60, p = .002). Results show a significant negative association between perceived control and anxiety symptomatology, providing partial support for models that assign a central role to control beliefs in explaining the development of anxiety disorders. These results also suggest the importance of considering the perception of control as a prime target for preventive actions and intervention aimed at reducing anxiety in school aged children. 相似文献

Based on the Job Demands-Resources (JD-R) model, the current study examined the moderating role of recovery experiences (i.e., psychological detachment from work, relaxation, mastery experiences, and control over leisure time) on the relationship between one job demand (i.e., role conflict) and work- and health-related outcomes. Results from our sample of 990 employees from Spain showed that psychological detachment from work and relaxation buffered the negative impact of role conflict on some of the proposed outcomes. Contrary to our expectations, we did not find significant results for mastery and control regarding moderating effects. Overall, findings suggest a differential pattern of the recovery experiences in the health impairment process proposed by the JD-R model. 相似文献

This paper describes the demographic, gender violence and psychopathological characteristics of 399 men in a specialized treatment programme for gender violence. Furthermore, a comparison of all the variables studied among the subjects referred by the court to the treatment programme (n = 276) and those who were imprisoned (n = 123) was conducted. The results showed the existence of numerous statistically significant differences between groups, primarily in psychopathological variables and in cognitive bias about women and violence use. In general, imprisoned batterers showed more irrational beliefs both about women and about violence as a strategy to cope with everyday difficulties. Moreover, batterers in prison had significantly higher scores on all psychopathological symptoms as assessed by SCL-90-R, as well as in most of STAXI-2 subscales. According to these results, batterers in prison showed a higher severity in variables studied than those who were referred by the court to the treatment programme. Implications of these results for further research and clinical practice are also commented on. 相似文献

In this article, we study the psychometric properties of a short scale (TRANS-18) which was designed to detect safe behaviors (personal and vehicle-related) and psychophysiological disorders. 244 drivers participated in the study, including drivers of freight transport vehicles (regular, dangerous and special), cranes, and passenger transport (regular transport and chartered coaches), ambulances and taxis. After carrying out an exploratory factor analysis of the scale, the findings show a structure comprised of three factors related to psychophysiological disorders, and to both personal and vehicle-related safety behaviors. Furthermore, these three factors had adequate reliability and all three also showed validity with regard to burnout, fatigue and job tension. In short, this scale may be ideally suited for adequately identifying the safety behaviors and safety problems of transport drivers. Future research could use the TRANS-18 as a screening tool in combination with other instruments. 相似文献

The general purpose of this work is to analyze the overlap between organizational identification and commitment. Specifically, our study focuses on the analysis of the differences and similarities between sense of belonging (a dimension of organizational identification) and affective commitment (a dimension of organizational commitment). In order to do this, we analyzed their discriminant validity and raised their relationship with variables that previous research had showed like precedent and subsequent variables of them: value congruence, perceived support, organizational citizenship behavior, and intention to continue in the organization. A total of 292 people at one organization completed surveys measuring the variables previously described. The results showed that sense of belonging and affective commitment are different concepts and they have different relationships with relation to precedent and subsequent variables. Affective commitment seems to be more useful than sense of belonging to predict organizational citizenship behavior aimed at the organization and intention to continue. Some practical implications are described. 相似文献

The goal of this study was to analyze the recidivism rate in minor offenders to whom a minimum intervention measure was applied after their first felony or misdemeanor, and to determine the variables associated with recidivism. The sample was made up of 154 minors from the province of Santa Cruz of Tenerife (Canary Islands, Spain). The information was collected from the database of the Minors' Court. The recidivism rate depends on the measure imposed, ranging between 14 and 40.6%. The degree of agreement between the Technical Team's proposal and the court decision was 70%. With regard to the variables associated with recidivism, a model was obtained through logistic regression that correctly classified 83.7% of the cases, and was made up of the variables perception of parenting problems, intervention of social services, and social isolation. 相似文献
