Controversies exist regarding the impact of psychological stress on the functioning of the immune system in humans. The aim of the present study, therefore, was to evaluate whether the condition of a pre-exam stress may or not modify resting lymphocyte subsets, as well as blood pressure and heart rate. About 22 medical residents of both sexes not suffering from any medical or psychiatric disorder were included in the study. Anxiety levels were measured by means of the Hamilton rating scale for anxiety (HRSA) and anxiety traits by means of the panic-agoraphobic spectrum self-report (PAS-SR) version and the obsessive-compulsive spectrum self-report (OBS-SR) version. The results showed that systolic blood pressure and heart rate increased significantly just before sitting an examination (t(1)) in all subjects, as compared with a calm situation (t(2)), in parallel with the increase in the HRSA total score, while no significant difference was observed in lymphocyte subsets at the two assessment times. However, men had a higher number of CD4+ cells than women at t(1) and t(2), while women showed a higher heart rate at t(1). In addition, significant correlations between CD4+ lymphocyte count and heart rate at t(1) or HRSA at t(2) were detected. These findings indicate that the acute stress determined by sitting for examination provokes changes in autonomic nervous system parameters, such as blood pressure and heart rate, as well as in the subjective feeling of anxiety, as shown by the increased HRSA total scores, which were not paralleled by modifications of lymphocyte subsets. However, individual differences, related to both sex and personality traits yet to be identified, seem to have an impact in shaping the stress response.  相似文献

While the philosophical study of shame has gained popularity, its application in the interpretation of the Hebrew Bible remains in its early stages. This paper delves into an analysis of shaming and unreasonable shame in the Book of Job, particularly in chapter 19. Through an examination of the Hebrew text and drawing on contemporary philosophical definitions of shame and shaming, I argue that Job perceives his friends, God, and the community to be employing shaming tactics against him, attempting to induce feelings of shame, a sentiment Job considers unjustified. In his case, shame is deemed unreasonable because Job has not violated any cherished values that would warrant such an emotion. Additionally, I demonstrate that while Job senses God shaming him, the biblical character acknowledges that his deity is the sole entity aware of his innocence—God's eyes perceive accurately, in contrast to humans', which only assess outward appearances. The role of God as the perfect witness to Job's life is fulfilled in the epilogue of the book, where Yahweh vindicates Job from the shame he has endured by publicly denouncing the serious faults of his friends.  相似文献

The aim of this study was to investigate the influence of contexts on cheating attitudes and behavior among Brazilian undergraduates. Participants were 77 Previous Choice Engineering and 70 Late Choice Engineering students. Previous Choice students enter the desired field chosen by examination, whereas Late Choice students' grades during the two first college years give them preference to choose the field. Their self-reported attitudes and behaviors were compared with those of 82 chemistry undergraduates from two universities (UNI-C and USP-C). The Late Choice students reported significant negative opinion about cheating, whereas Previous Choice students, especially women, reported significant favorable opinion. Furthermore, Previous Choice students reported colleagues more frequently gave them answers on examinations than Late Choice students. The two university groups in chemistry had intermediate scores. Deterrents of cheating strongly embedded in the student culture were found among Late Choice engineering undergraduates which may be explained by social learning theory.  相似文献

The modified version of the Conflict Tactics Scale (M-CTS), originally created by Straus in 1979, is one of the most extensively used instruments to detect violent verbal and physical behaviours in youths' and adolescents' dating relations. The aim of the present work was to analyze the psychometric properties of the instrument and to validate its adequacy in the Spanish population. The sample was made up of 5,355 Spanish youths from the Community of Madrid, ages between 16 and 26 years. By means of confirmatory factor analysis, four factors that were consistent with the theory and with previous research were identified: arguments, psychological/verbal aggression, slight physical aggression, and severe physical aggression. It is concluded that the scale assesses the presence of various types of aggression in youths' and adolescents' dating relationships with sufficient psychometric guarantees.  相似文献

Existing work on the effects of social comparison on envy and generosity typically involves manipulation of social comparison with respect to dimensions that carry personal meaning and reflect upon the self, for example, performance, ability, or achievement. In the current work, we examine the effects of social comparison based on a purely arbitrary, manipulated situation. We measure malicious envy via monetary decisions that have real consequences for the target of comparison, in place of a self-reported questionnaire. In addition, we test the effects of the preliminary social comparison on generosity in a subsequent and ostensibly unrelated situation. In Experiment 1 we demonstrate the effect of randomly manipulated upward social comparison on a monetary allocation decision, and we establish the link between this allocation decision and malicious envy. In Experiment 2 we show that upward comparison affects not only malicious envy towards the target of the comparison but also decreases generosity towards a third party in a subsequent, ostensibly unrelated situation. Experiment 3 shows the effect of this type of social comparison, beyond a specific direction, on reducing generosity towards a third party.  相似文献

Recent findings indicate that toddlers can use geometric cues to locate an object hidden in a corner of a rectangular room after being disoriented [Cognition 61 (1996) 195]. It has been suggested that locating the object involves reestablishing one's initial heading. The present experiments examine search behavior after disorientation. We find that toddlers go directly to a particular corner, indicating that they do not have to reestablish their original heading. It also has been suggested that toddlers ability to use geometric cues is limited to surrounding spaces. We find that toddlers can locate an object from outside as well as from inside a space, although the task is harder from outside. Based on these results, we argue that while toddlers do not represent their position relative to a particular portion of a space, they nevertheless may represent their position relative to the entire space (i.e., outside vs. inside).  相似文献

This study aimed to investigate: (1) the influence of gender, sibling age, and sibling gender on sibling bullying and victimization; (2) the links between personality characteristics, quality of the sibling relationship, and sibling bullying/victimization; (3) the association between sibling and school bullying/victimization, and the direct and indirect associations between personality variables and school bullying/victimization. The sample comprised 195 children (98 boys and 97 girls, aged 10–12 years). Instruments included: a self‐report questionnaire for bullying and victimization, the Big Five Questionnaire for Children and the Sibling Inventory of Behaviour. Results highlighted that the presence of an older brother is a risk factor for the emergence of sibling victimization. For both boys and girls, high levels of conflict in the dyad and low levels of empathy were significantly related to sibling bullying and sibling victimization. For males, energy was associated with sibling bullying and indirectly to school bullying; friendliness and high emotional instability were directly associated with school bullying. School victimization was directly associated with emotional instability for both males and females. Finally, both sibling bullying and sibling victimization were associated with bullying and victimization at school. The discussion highlights the role of a multi‐contextual approach to understand and prevent bullying.  相似文献
