The purpose of this study was to test an explanatory model of the relationships between physical self-concept and some healthy habits. A sample of 472 adolescents aged 16 to 20 answered different questionnaires assessing physical self-concept, physical activity, intention to be physically active and consumption of alcohol and tobacco. The results of the structural equation model showed that perceived sport competence positively correlated with current physical activity. Body attractiveness positively correlated with physical activity in boys and negatively in girls. Current physical activity positively correlated with the intention to be physically active in the future and negatively with the consumption of alcohol and tobacco. Nevertheless, this last relationship was only significant in boys. The results are discussed in connection with the promotion of healthy lifestyle guidelines among adolescents. This model shows the importance of physical self-concept for engaging in physical activity in adolescence. It also suggests that physical activity is associated with the intention to continue being physically active and with healthy lifestyle habits. 相似文献

The authors use examples of youth civic engagement from Chile, South Africa, Central/Eastern Europe, and the United States--and also emphasize diversities among youth from different subgroups within countries--to illustrate common elements of the civic domain of youth development. These include the primacy of collective activity for forming political identities and ideas and the greater heterogeneity of civic compared to other discretionary activities, the groupways or accumulated opportunities for acting due to the groups (social class, gender, ethnic, caste, etc.) to which a young person belongs, and the role of mediating institutions (schools, community-based organizations, etc.) as spaces where youths' actions contribute to political stability and change. 相似文献

Here we try to offer a panoramic view on the evolution of the concept of introjection in Ferenczi's thinking, until its culmination in the last annotation of Notes and Fragments on December 26, 1932. In this final note, Ferenczi invented the neologism intropression in which he tried to articulate the notion of introjections with the devastating effects of violence and parental repression, and a definite way to conceive the analytical practice. 相似文献

I present a new interpretation of reaction time (RT) data from behavioural experiments. From a physical perspective, the entropy of the RT distribution–the temporal entropy–provides a model-free estimate of the amount of processing performed by the cognitive system. This new measure shifts the focus from the conventional interpretation of RTs being either long or short, into their distribution being more or less complex in terms of entropy. I introduce the formulation of the theory, followed by an empirical test using a large database of human RTs in lexical processing tasks. Using the measure, I obtain estimates of the processing loads to individual stimuli (i.e., words), as well as estimates for the overall rate at which the system processes information in these tasks. The relation between the temporal entropy and the RTs can be captured by a simple linear equation. I argue that this equation constitutes the equivalent of a ‘phase diagram’ of a task, providing indications about the different mechanisms that are at play in it, and locating critical points signalling the transitions between these different mechanisms. The results suggest an adaptive system that adjusts its operational processing speed to the demands of each individual stimulus. This finding is in contradiction with a generalization of Hick’s Law positing a relatively constant processing speed within an experimental context. 相似文献

The aim of the study was to assess the influence on reactivity to food images of the following variables: craving-trait, positive or negative mood state, and food restriction. Emotional modulation of the defense startle reflex (RMS) was assessed in 26 women at risk of suffering from bulimia nervosa; they were assigned one of to two groups: high craving-trait and low craving-trait. Before the test, positive or negative mood and restriction vs. non-restriction states were induced in each of the groups. Skin conductance response (SCR) and electromyogram activity from the orbiculari oculi region were recorded after the auditory stimuli; questionnaires such as Food Craving Trait Questionnaire (FCQ-T) and the Self-assessment Manikin (SAM) were used. Results showed that negative affect produced a negative valence of food images, more arousal, and more loss of control, as well as higher SCRs. Subjects with low FCQ-T levels reduced their RMS to food images as a consequence of experiencing positive emotions; when emotions were negative, their RMS increased. 相似文献

This study is part of an investigation aimed at assessing the cognitive-emotional process of emotional recognition in somatizing patients. The specific objective was to verify whether there were differences in the self-assessment of emotional reaction among patients with somatization and non-clinical controls. To obtain the self-assessment of their emotional reaction in the affective dimensions of valence and activation in clinical and control participants, we resorted to a procedure that minimizes the use of verbal skills and comprehension. Participants were 119 people, 47 patients and 72 non-clinical participants. The prevalence of alexithymia in the clinical group was 42.55%, whereas in non-clinical controls, it was 30.55%. Results showed the existence of a deficit in the clinical group's self-assessment of activation in response to the corresponding images with high levels of the affective dimension of activation and high valence images, associated with the clinical condition but not with alexithymia. Alexithymia has a modulatory effect on the clinical participants' and controls' evaluation of the valence of the unpleasant images or of low valence pictures. 相似文献

This article reviews recent research about academic learning and school coexistence in adolescence from a gender perspective. It focuses on the research developed by the Preventive Psychology research group (UCM), specially the results from the Spanish National Study of School Coexistence using a sample of 22,247 secondary school students. Research shows that girls are overrepresented in positive indicators whereas boys are in negative indicators, not only in academic adjustment but also in school coexistence. Girls' better academic achievement can be explained by their higher tendency to overcome sexism: they identify with traditional masculinity values (such as success orientation) without giving up traditional femininity values (such as empathy). Based on this, the following conclusions are reached: 1) to extend the advantages of equality also to men; 2) to emphasize that sharing academic contexts and activities is necessary but sufficient to construct equality; and lastly, 3) to improve school coexistence, it is necessary to adopt a integrative gender approach to prevent any kind of violence, including violence against women. 相似文献
