Three pigeons learned to peck four colors in a particular sequence, regardless of how these colors were positioned on four response keys and without feedback following each response. This demonstrates that serial learning is possible in subprimate animals. 相似文献

The purpose of this study was to examine the relation of depression and anxiety to cancer patients' medical decision-making. Participants were 79 rural and urban cancer patients undergoing chemotherapy. The four decisional styles of the Decisional Processing Model were the independent variables. Dependent variables were anxiety and depression, measured by Spielberger's State-Trait Anxiety and the Center for Disease Control Depression Scale, respectively. Consistent with the Decisional Processing Model, analysis suggested that patients make medical decisions by information seeking, information processing, advice following, or ruminating. Decisional style did not vary according to type or stage of cancer, prognosis, time elapsed since initial diagnosis, or whether cancer was initial or recurrent. Decisional style did not systematically vary with depression and anxiety suggesting how a person makes decisions is a stable personality trait. Thus, decision-making may follow a cognitive schema. It is likely that patients' decisional styles help to manage anxiety and depression when confronted with life-threatening illness. Implications for informed consent and patients' involvement in decision-making are discussed. 相似文献

Two experiments were conducted to assess gender differences in knowledge of U.S. state names and locations. Subjects for both experiments were drawn from a population that was approximately 95% Caucasian, 2% Native American, 1% Black, 1% Asian, and 1% Hispanic. Experiment 1 demonstrated superior male performance with respect to ability to correctly label state outlines on a blank map. Providing subjects with a list of state names (as a recall aid) resulted in performance deficits that were of equivalent magnitude for both males and females. It is suggested that this may have changed subjects' labeling strategy. Experiment 2, which assessed ability to list state names, showed no gender differences and no effect for providing a blank map (as a recall aid). Therefore, the performance differences obtained in Experiment 1 appear mediated by a gender difference in geographical knowledge and not by a gender difference in knowledge of state names. Implications of geographical knowledge deficits are briefly discussed. 相似文献

Participating in a laboratory study of the effects of stress on eating, healthy, nonsmoking men and women were shown a film about industrial accidents (stress condition) or a pleasant travelogue (control condition) and had access to sweet, salty, and bland snack food. Analyses of food consumption data revealed a significant interaction between sex of subject and the stress manipulation: Stress markedly and significantly decreased food consumption by men but resulted in some increased food consumption by women. Across the three food taste categories, men consistently ate less under stress than they did in the control condition. In contrast, women ate nearly twice as much sweet food and more bland food under stress than they did in the control condition, but these effects were not statistically significant. These results indicate that the relationship between stress and eating depends on the sex of the subject and may relate to type of food available. Contrasting generalizations about stress and eating reported in the archived literature can largely be reconciled by considering these interacting variables. 相似文献

Sleep problems are prevalent among Veterans. Left untreated, such problems may elevate psychological distress and increase risk of subsequent mental health disorders. Psychological resilience may buffer against negative psychological outcomes, yet the relationship between sleep and resilience has not been studied. This study explored poor sleep, resilience, and psychological distress using questionnaires collected as part of the Study of Post-Deployment Mental Health. Participants (N = 1,118) had served in the US military since September 11, 2001, had one or more overseas deployments, and were free from a past-month DSM-defined mental health disorder. Hierarchical linear regression was used to examine the association between poor sleep quality (Pittsburgh Sleep Quality Index total score) and psychological distress (Global Symptom Index; Symptom Checklist-90-R), controlling for demographic and health characteristics. Moderation analyses tested for a potential buffering effect of resilience (Connor-Davidson Resilience Scale). Poor sleeping Veterans had worse physical and psychological health, lower resilience, and endorsed more lifetime traumatic events. Poor sleep was associated with greater psychological distress controlling for health and demographic characteristics. Both resilience factors—adaptability and self-efficacy—had significant buffering effects on the relationship between poor sleep and psychological distress, suggesting that resilience may protect against negative outcomes in poor sleepers. Additional research is warranted to better understand the relationships between sleep, resilience, and psychological distress. Such research may inform pertinent prevention efforts, including interventions that improve sleep, enhance resilience, and protect against incident mental health diagnoses. 相似文献

Video has been used successfully in psychosocial interventions to help train communication skills, document behaviors, and as a feedback tool for behavior modification strategies. The need for equipment portability, together with editing expertise, has limited video use in sport psychology. Newer digital video systems help overcome these problems, meaning that sport psychologists can readily use this technology in the field. We discuss and provide experiential observations of how digital video can be used to improve player, coach, and team performance. Also reviewed are new consultation opportunities for sport psychologists with video skills. These new areas center on perceptual skills training and talent identification using perceptual skills testing. 相似文献

Abstract The primary purpose of this study was to identify 10 leading former Soviet Union sport psychologists and describe their major contributions. The investigators also desired to determine the status and future directions of sport psychology in Russia and the other new countries that formerly comprised the Soviet Union. Balloting for the leading sport psychologists occurred at the newly formed meeting of the Interstates Association of Sport Psychologists (IASP) and 10 persons were identified: Anatoli V. Alekseev, Marina V. Ennolaeva, Leonid D. Gissen. Gennadij D. Gorbunov, Nickolai A. Hudadov. Piotr A. Jorov. Juri A. Kolomeitzev, Albert V. Rodionov, Vladimir R. Sopov, and Bronislav A. Viatkin. These individuals were subsequently interviewed and the results indicated that although many cutbacks have occurred during the previous decade (1980–1990). sport psychologists continue their work. They are developing new and innovative ways to help athletes improve their individual and collective performance. Their work in psychodiagnostics is exemplary. Nevertheless, the future of sport psychology remains uncertain in the Former Soviet Union. 相似文献

Background: We report on the preliminary results of two independent studies that (1) compare the hair cortisol concentrations (HCC) of healthy controls with patients displaying post-traumatic stress symptoms (PTSS, study 1+2), (2) investigate whether pre-trauma HCC are predictive for the development of acute stress symptoms (ASS) and PTSS (study 1) and (3) determine whether HCC correlate with PTSS in a clinical sample of children (study 2).Methods: In study 1, the clinical symptoms of 35 minors were examined one (T1) and seven weeks (T2) after surgery following an accident. Hair samples were taken after the accident that reflect cortisol secretion over the past three months before the accident (healthy controls). In study 2, HCC and PTSS symptoms were cross-sectionally assessed in 22 minors who had experienced a psychological trauma.Results: The HCC of patients with PTSS were lower than the HCC of healthy controls (study 1+2). Secondary analyses showed that HCC were significantly lower in male PTSS patients than in male healthy controls, whereas the HCC in females were comparably low in both groups. Pre-trauma HCC did not predict the total ASS and PTSS scores (study 1) and HCC were not directly related to the total PTSS scores (study 2). 相似文献
