This study examined whether participation in elite sport interacts with stress in decreasing or increasing symptoms of depression and anxiety among adolescents, and further, whether the interplay between participation in high-performance sport and stress is related to the perceived quality of sleep. 434 adolescents (278 girls, 156 boys; age: M = 17.2 yr.) from 15 "Swiss Olympic Sport Classes" and 9 conventional classes answered a questionnaire and completed a 7-day sleep log. Analyses of covariance showed that heightened stress was related to more depressive symptoms and higher scores for trait-anxiety. Moreover, those classified as having poor sleep by a median split cutoff reported higher levels of depressive symptoms. No significant (multivariate) main effects were found for high-performance sport athletes. Similarly, no significant two- or three-way interaction effects were found. These results caution against exaggerated expectations concerning sport participation as a stress buffer. Nevertheless, participation in high-performance sport was not found to be an additional source of distress for adolescents who reported high stress levels despite prior research that has pointed toward such a relationship. 相似文献

This prospective study examined the variability within clinical characteristics of antenatal maternal depression and cortisol levels for associations with newborn infant behavior using the Neonatal Behavioral Assessment Scale (NBAS; T.B. Brazelton, 1984 ). Participants were 81 pregnant women at risk for perinatal depression given their histories of depression prior to pregnancy. We took into consideration not only whether the woman experienced antenatal depression but also whether the depression met diagnostic criteria and variability in timing (onset and occurrence) of antenatal depression and symptom severity. Infants of mothers who became depressed during pregnancy scored less optimally on a subset of the NBAS scales, specifically those scales related to infant neuroregulation. Among the clinical characteristics of depression, the fetus' overall exposure to mothers' depression (reflected in the mean) was most often and most strongly associated with NBAS scales. In terms of timing, third‐trimester exposure was significantly related to newborn behavior. The findings are discussed within the S.H. Goodman and I.H. Gotlib ( 1999 ) model for transmission of psychopathology to offspring of depressed mothers. 相似文献

Recent research suggests two ways of making decisions: an intuitive and an analytical one. The current study examines whether
a secondary executive task interferes with advantageous decision-making in the Game of Dice Task (GDT), a decision-making
task with explicit and stable rules that taps executive functioning. One group of participants performed the original GDT
solely, two groups performed either the GDT and a 1-back or a 2-back working memory task as a secondary task simultaneously.
Results show that the group which performed the GDT and the secondary task with high executive load (2-back) decided less
advantageously than the group which did not perform a secondary executive task. These findings give further evidence for the
view that decision-making under risky conditions taps into the rational-analytical system which acts in a serial and not parallel
way as performance on the GDT is disturbed by a parallel task that also requires executive resources. 相似文献

Excessive or addictive Internet use can be linked to different online activities, such as Internet gaming or cybersex. The usage of Internet pornography sites is one important facet of online sexual activity. The aim of the present work was to examine potential predictors of a tendency toward cybersex addiction in terms of subjective complaints in everyday life due to online sexual activities. We focused on the subjective evaluation of Internet pornographic material with respect to sexual arousal and emotional valence, as well as on psychological symptoms as potential predictors. We examined 89 heterosexual, male participants with an experimental task assessing subjective sexual arousal and emotional valence of Internet pornographic pictures. The Internet Addiction Test (IAT) and a modified version of the IAT for online sexual activities (IATsex), as well as several further questionnaires measuring psychological symptoms and facets of personality were also administered to the participants. Results indicate that self-reported problems in daily life linked to online sexual activities were predicted by subjective sexual arousal ratings of the pornographic material, global severity of psychological symptoms, and the number of sex applications used when being on Internet sex sites in daily life, while the time spent on Internet sex sites (minutes per day) did not significantly contribute to explanation of variance in IATsex score. Personality facets were not significantly correlated with the IATsex score. The study demonstrates the important role of subjective arousal and psychological symptoms as potential correlates of development or maintenance of excessive online sexual activity. 相似文献

We investigated the possibility that mothers modify their infant‐directed actions in ways that might assist infants’ processing of human action. In a between‐subjects design, 51 mothers demonstrated the properties of five novel objects either to their infant (age 6–8 months or 11–13 months) or to an adult partner. As predicted, demonstrations to infants were higher in interactiveness, enthusiasm, proximity to partner, range of motion, repetitiveness and simplicity, indicating that mothers indeed modify their infant‐directed actions in ways that likely maintain infants’ attention and highlight the structure and meaning of action. The findings demonstrate that ‘motherese’ is broader in scope than previously recognized, including modifications to action as well as language. 相似文献

Action in connection with the therapeutic process is often equated with acting out. The subtle behaviour that belongs to ?the complicated system of transmitting and receiving unconscious signals? (Sandler), with which the patient attempts to make the analyst behave as the object of transference or to fulfill an unconscious desire, is also described as acting out or micro-acting out (Treurniet). This fine-grained action, however, means nothing; it is not symbolic or communicative action. Its intention is, rather, to trigger effects and induce interactions. It occurs not only on the side of the analysand but also on that of the analyst, and is part of the unconscious communication in the therapeutic process. Presented here are some of the various interactive ways and means with which the analyst is prompted into unconscious action and certain, unnoticed, ways in that he turn ?treats? the patient. The analyst's action responses can bear the character of interpretations with which he may unintentionally reveal how he regards the behaviour of the patient. 相似文献

This paper describes a simple and efficient method to increase the D/A output resolution of an 8-bit microcomputer, as exemplified on the Apple II. The “distributive method” can increase the final output resolution up to 32K with two 8-bit analogic channels. A simple interface based on balanced sets of resistors and driver software are described. Some applications are also reported. 相似文献

We evaluated hemispheric functions ipsilateral to the side of carotid endarterectomy (CEA) in patients with a severe stenosis in the left or right carotid artery. Assessments took place 1 day before and 3 months after CEA. Only right-handed males were included. Nineteen patients underwent surgery of the left carotid artery and 17 of the right. Valid instruments for hemispheric function were included, such as verbal dichotic listening, finger tapping, and a lateralised test for motor planning. Results showed that, preoperatively, patients had lower scores compared to norms on the laterality tests, and on a visuoconstructive test. There was no evidence of ipsilateral improvement related to side of surgery. Left ear dichotic listening improved, which was seen in both left and right surgery groups. Also in both groups, left- and right-hand movement speed in the motor planning test decreased. Conclusion is that beneficial ipsilateral cognitive change after CEA in patients with severe stenosis in one of the carotid arteries may not be demonstrated, even if valid instruments for hemispheric function are included. 相似文献
