Alcohol, tobacco and other drug use continue to pose serious public health concerns among youth. Bullying victimization has been identified as a risk factor and religiosity a protective factor for adolescent substance use. No previous research has examined the potential moderating role of religiosity. We explore the association between bullying victimization and substance use in adolescents with low and high levels of religiosity. A cross-sectional survey was conducted with a representative sample of high school students in greater Beirut. Binary and multinomial logistic models were used, adjusting for demographics, and stratified by level of religiosity. Of the 986 students responding to the survey, 65% were females; 48% had experienced some form of bullying; and 52% self-rated as low in religiosity. Between 10 and 30% were current users of alcohol or tobacco. Students of lower religiosity levels who had been bullied were more likely to use substances than those who self-rated as high religiosity. Religiosity may be a potential moderator of the association between being bullied and substance use, but the exact mechanisms and underlying reasons need further investigation.

Past research has examined the stress resiliency of individuals high in sense of personal-mastery. However, it has been theorized that within more collectivist cultures, a sense of shared efficacy, which we call communal-mastery, may be more central to people's resiliency in the face of challenging life circumstances. We compared the impact of sense of self-mastery (i.e., I am the key to my success) to that of communal-mastery (i.e., I am successful by virtue of my social attachments) in a prospective study among a group of rural 103 Native American women residing on Indian Reservations in Montana. We found that women high in communal-mastery experienced less increase in depressive mood and anger, especially when faced with high stress circumstances, than women who were low in communal-mastery. In addition, the beneficial impact of communal-mastery was found to be more effective than self-mastery for these women. 相似文献
Although there is growing knowledge about intracellular mechanisms underlying neuronal plasticity and memory consolidation and reconsolidation after retrieval, information concerning the interaction among brain areas during formation and retrieval of memory is relatively sparse and fragmented. Addressing this question requires simultaneous monitoring of activity in multiple brain regions during learning, the post-acquisition consolidation period, and retrieval and subsequent reconsolidation. Immunoreaction to the immediate early gene c-fos is a powerful tool to mark neuronal activation of specific populations of neurons. Using this method, we are able to report, for the first time, post-training activation of a network of closely related brain regions, particularly in the frontal cortex and the basolateral amygdala (BLA), that is specific to the learning of an odor-reward association. On the other hand, retrieval of a well-established associative memory trace does not seem to differentially activate the same regions. The amygdala, in particular, is not engaged after retrieval, whereas the lateral habenula (LHab) shows strong activation that is restricted to animals having previously learned the association. Although intracellular mechanisms may be similar during consolidation and reconsolidation, this study indicates that different brain circuits are involved in the two processes, at least with respect to a rapidly learned olfactory task. 相似文献
Recently, quantitative models based on signal detection theory have been successfully applied to the prediction of human accuracy in visual search for a target that differs from distractors along a single attribute (feature search). The present paper extends these models for visual search accuracy to multidimensional search displays in which the target differs from the distractors along more than one feature dimension (conjunction, disjunction, and triple conjunction displays). The model assumes that each element in the display elicits a noisy representation for each of the relevant feature dimensions. The observer combines the representations across feature dimensions to obtain a single decision variable, and the stimulus with the maximum value determines the response. The model accurately predicts human experimental data on visual search accuracy in conjunctions and disjunctions of contrast and orientation. The model accounts for performance degradation without resorting to a limited-capacity spatially localized and temporally serial mechanism by which to bind information across feature dimensions. 相似文献
The Five-factor model (FFM; Digman, 1990; Goldberg, 1990) and Loevinger's (1994) theory of ego development are two active research traditions that are often construed as incompatible approaches to the study of personality. For example, each theory proposes a different view of the concept of conscientiousness. Loevinger argued that FFM conscientiousness, which emphasizes attributes such as order, self-discipline, and achievement striving, lacks a moral component and is more similar to the conformist stage in her theory. To investigate these claims, we administered the Revised NEO-Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) and the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) to 120 university students on 2 separate occasions. Together, the five traits of the FFM significantly predicted item sum scores from the WUSCT (multiple R = .54). Unique linear relationships of Openness to Experience and Agreeableness with ego level demonstrated that the two theories proposed similar constructs. We argue that these two FFM dimensions have conceptual relevance to the cognitive and interpersonal aspects of the ego development construct. We draw further connections between these FFM dimensions, ego development, and human values. 相似文献
As research is limited the purpose of this study was to investigate dynamic visual acuity while cycling at different exercise loads. Accuracy of dynamic visual acuity scores of 20 college-age participants was analyzed by a repeated-measures analysis of variance which indicated improved dynamic visual acuity during cycling as the intensity of exercise increased. A retention test conducted two days after testing yielded evidence of trainability of dynamic visual acuity. In the discussion findings were compared to other visual functions associated with exercise. 相似文献
The processing of Prepositional compounds (typical Neo-latin noun--noun modifications where a head noun is modified by a prepositional phrase, e.g., mulino a vento, windmill) was preliminarily studied with a group of six agrammatic aphasic patients, and, in more detail, with a further agrammatic patient (MB). Omission was the most frequent error type in naming, whereas in the other tasks (repetition, reading, writing, and completion) errors were mostly substitutions of the target preposition. This happened even with fully lexicalized compound forms, i.e., those forms where the linking preposition is syntactically and semantically opaque. These findings are interpreted in terms of a dual-route theory of lexical access to morphologically complex words. 相似文献
