This study evaluated the internal consistency of a Spanish version of the short form of the Francis Scale of Attitude Toward Christianity based on responses of 405 Colombian adolescent students ages 13 to 17 years. This translated short-form version of the scale had an internal consistency of .80. This estimate indicates suitable internal consistency reliability for research use in this population. 相似文献

This study utilized the theory of reasoned action to examine how Latina adolescents' intentions to have sex in the coming month were influenced by their general attitude toward having sex and their perceptions of general social norms about having sex. Eighty-four Mexican American and Central American adolescent females ages 14 to 19 participated in telephone interviews. One group of 41 Mexican American adolescents was obtained through a telephone survey and the second group of 43 pregnant or parenting Mexican American and Central American adolescents was recruited from health clinics. Path analysis conducted separately for the two groups indicated that, for the clinic group, perceptions of general social norms, but not general attitude, predicted intentions to have sex; and for the survey group, whether they were sexually active directly predicted perceptions of general social norms and intention to have sex. Adolescents' perceptions of what significant others desired of them, but not their motivation to comply, predicted perceptions of general social norms about having sex. Results underscore the importance of social norms for Latina adolescents when they are considering whether or not to have sex. 相似文献

Improvement in perception takes place within the training session and from one session to the next. The present study aims at determining the time course of perceptual learning as revealed by changes in auditory event-related potentials (ERPs) reflecting preattentive processes. Subjects were trained to discriminate two complex auditory patterns in a single session. ERPs were recorded just before and after training, while subjects read a book and ignored stimulation. ERPs showed a negative wave called mismatch negativity (MMN)—which indexes automatic detection of a change in a homogeneous auditory sequence—just after subjects learned to consciously discriminate the two patterns. ERPs were recorded again 12, 24, 36, and 48 h later, just before testing performance on the discrimination task. Additional behavioral and neurophysiological changes were found several hours after the training session: an enhanced P2 at 24 h followed by shorter reaction times, and an enhanced MMN at 36 h. These results indicate that gains in performance on the discrimination of two complex auditory patterns are accompanied by different learning-dependent neurophysiological events evolving within different time frames, supporting the hypothesis that fast and slow neural changes underlie the acquisition of improved perception. 相似文献

'Soul' is one of the fundamental categories of our consciousness. What does it mean for a child? Russian children from an urban area (n = 148) were interviewed to answer this question. The data shows that children understand soul as an internal phenomenon, which is responsible for the social, emotional and moral life of a person. Children believe that the soul has primacy over the body, serves to control and guide human behaviour and performs such functions as emotions, thinking, memory and wishes. Children communicate animistic, ethical and psychological meanings to the concept of soul. Comparative data obtained in four age groups of children (5-6, 6-7, 7-8, 9-10 year olds) are discussed. 相似文献

Type and token frequency have been thought to be important in the acquisition of past tense morphology, particularly in differentiating regular and irregular forms. In this study we tested the role of frequency in two ways: (1) in bilingual children, who typically use and hear either language less often than monolingual children and (2) cross-linguistically: French and English have different patterns of frequency of regular/irregular verbs. Ten French-English bilingual children, 10 French monolingual and 10 English monolingual children between 4 and 6 years watched a cartoon and re-told the story. The results demonstrated that the bilingual children were less accurate than the monolingual children. Their accuracy in both French and English regular and irregular verbs corresponded to frequency in the input language. These results are consistent with the hypothesis that children learn past tense morphemes by analogy with other words in their vocabularies. We propose a developmental sequence based on conservative generalization across a growing set of verbs. 相似文献

Many patients with chronic pain also exhibit elevated levels of health anxiety. This study examined the effect of health anxiety on the use of safety-seeking behaviors (SSBs) in pain-provoking situations. Participants were 20 chronic back pain patients with high health anxiety (Group H), 20 with low health anxiety (Group L) and 20 pain-free controls (Group C). Two physical tasks were video recorded, and compared both for overt pain behavior (identified by blind observers following a standardized procedure) and for the occurrence of SSB (identified by showing the participants video playback and asking them to specify motivation for all actions/behaviors displayed during the tasks). While there were no differences in the display of overt pain behaviors, Group H deployed a greater number of SSBs than Groups L and C. This finding held true for both tasks and remained significant when concurrent pain and mood ratings were statistically controlled for. SSB was correlated with catastrophizing thoughts but not pain intensity; pain intensity was correlated with overt pain behavior but not catastrophizing. Taken together, these findings suggest that SSB is distinct from overt pain behavior and may be a defining characteristic of chronic pain patients reporting high levels of health anxiety. 相似文献

The purpose of the present study is to analyse the relationship between sleep, burnout, and job strain in a sample of 316 healthy workers from various professional sectors. Multiple significant correlations between the principal sleep parameters, the dimensions of burnout, and job strain were found. The regression analyses show that sleep quality and various dimensions of job strain are significant predictors of several aspects of burnout. Sleep quality explains an even higher percentage of the variance in emotional exhaustion than the variance explained by more well-known variables such as job demands. Moreover, sleep quality interacts with aspects of job strain in its influence on the dimensions of burnout, although the exact relationship between these variables needs to be investigated in future longitudinal studies. Our results suggest that interventions to optimise sleep habits could prevent or alleviate burnout and could be a part of organisational work. 相似文献
