In March 2020, in response to the COVID-19 pandemic, Canadian provincial governments instituted a variety of public health measures that included social distancing and isolation, which may have had unintended consequeses. According to the Loneliness and Sexual Risk Model, gay, bisexual, and other men who have sex with men (GBM) often cope with loneliness through risky sexual behaviors. Previous studies have demonstrated that COVID-19 measures such as social distancing and isolation led to increases in loneliness; thus, these measures may also have led to elevated sexual risk-taking among some GBM. Participants were recruited from an ongoing cohort study on GBM health and well-being, and were included in the current analysis if they had completed relevant study questions (n = 1134). GBM who reported lower levels of social support pre-COVID-19, were younger, and lived alone each reported greater loneliness during the first year of COVID-19. Although feelings of loneliness did not predict sexual risk-taking within the first year of COVID-19, loneliness did predict greater sexual risk-taking 6 months later. Additionally, younger GBM and those living alone were more likely to engage in sexual risk-taking at both COVID-19 data collection points. These findings offer some support of the Loneliness and Sexual Risk Model; however, it is possible that the unique circumstances of the COVID-19 pandemic resulted in a temporary suspension of this association, as many GBM took steps to protect themselves and partners in the context of COVID-19.  相似文献

Investigations of a mirror-image transfer effect in pigeons   总被引:2,自引:1,他引:1       下载免费PDF全文
In two separate experiments, pigeons trained binocularly to peck a key on which an oblique line (e.g., 60 degrees counter-clockwise rotation from horizontal) was projected yielded bi-modal angularity generalization gradients in extinction, with peaks of responding at both the training stimulus and its mirror image (in this case 120 degrees ). This mirror-image transfer effect may be analogous to an "octave effect" in auditory generalization, but Mello's finding of a mirror-image reversal transfer effect following monocular training in pigeons suggests an alternative interpretation.  相似文献

As part of this special issue on psychology in primary care settings, we describe the Department of Veterans Affairs' (VA's) new approach to education for practice in the primary care setting and we concurrently address some general issues related to the education of clinical psychologists for practice in this setting. In this article we argue that the primary care psychologist, in parallel with the generalist in medicine, must have a strong generic background in clinical psychology in order to gain the broad range of clinical skills necessary to function effectively as an in-depth generalist (IDG) who is capable of addressing the variety of psychological issues that emerge in the primary care setting. The IDG model of professional practice, which we believe is best suited for primary care/managed care settings, requires extensive training in generic clinical skills and increased time devoted to its implementation at both the predoctoral and the postdoctoral levels.  相似文献

Stage theories and empirical studies have concentrated on a few periods of childhood (e.g., age 5 to 7 years) as important times of transition. On the basis of ethnographic suggestions that the age period 8 to 10 years also involves interesting changes, the authors carried out a search of published empirical studies for findings of transitions in capabilities at 8 to 10 years. An annotated bibliography is provided summarizing the studies found in a 5-year period in three journals. The authors discuss possibilities for characterizing the transition at age 8 to 10, as well as how such a transition meshes with the concept of stage.  相似文献

Six mentally retarded adults, equally divided into two treatment groups, were provided with individualized social skills training programs. Treatment, evaluated via a multiple-baseline design strategy, was sequentially and cumulatively applied across target behaviors over a four-week intervention period. Behavioral observation probes and social validation measures served as the primary dependent variables. Results indicated that (a) treatment was effective for virtually all behaviors across all subjects, (b) improvements occurred for both training and generalization scenes, and (c) behavioral performance was maintained one month following the termination of treatment.  相似文献

Lucy Bregman's approach to Schreber'sMemoirs is scrutinized and found to be based on a number of fallacious and contradictory assumptions that call her interpretation of the book as personal religious myth into question. A social constructionist approach to mythology maintained by Berger and Luckmann is advanced, suggesting that at best Schreber's work qualifies as a quasi-mythical attempt to explain the source of his personal sociopsychic suffering. The family and interpersonal dynamics of Schreber's quasi-myth are investigated. Similarities to other cases of psychotic quasi-myths are noted and a general relationship between oppressive socialization and psychotic communications is advanced, as well as a specific alternative interpretation of Schreber's work to that proposed by Bregman.Nathan Church, M.S., is currently teaching at Douglass College of Rutgers University, where he is nearing completion of his Ph.D. in sociology.  相似文献

A token reinforcement program involving two levels of token value and backup reinforcers to increase journal reshelving behavior in a large university library was experimentally evaluated. Results showed that instructions (in which signs asked users to reshelve journals) had no impact. By contrast, token reinforcement contingent on reshelving behavior led to a marked increase in journals reshelved. A return to instructions-only conditions, when data were corrected for library usage, showed an increase in unreshelved journals over the token reinforcement period, though the increase was not to baseline levels. For the next 11 months, library staff maintained a modified token program. Follow-up data collected after that interval showed that number of unreshelved journals remained markedly lower than levels at baseline and the first instructions-only period, though they were slightly higher than at the token reinforcement period. Token reinforcement of the variety employed in this study constitutes an efficient, economical means of changing the behavior of library users who fail to reshelve books and journals.  相似文献
