To assess the psychosocial responses of hospital workers to acquired immune deficiency syndrome (AIDS), 237 hospital employees were interviewed. Information was obtained on frequency and nature of contact with AIDS patients; knowledge about AIDS; attitudes about AIDS and about homosexuality; and stresses related to AIDS care. Four indices were developed: AIDS-Contact, AIDS-Phobia, Homophobia, and AIDS-Stress. Misperceptions and fears about AIDS, as well as negative attitudes about individuals with the disease, were common. AIDS-Phobia was positively correlated with Homophobia and AIDS-Stress. AIDS-Phobia and AIDS-Stress were negatively correlated with AIDS-Contact. More patient contact was associated with lower levels of perceived stress, except for those with frequent but impersonal patient contact. Strategies for educational programs based on results are proposed. 相似文献

The processing of sine-wave gratings presented to the left and right visual fields was examined in four experiments. Subjects were required either to detect the presence of a grating (Experiments 1 and 2) or to identify the spatial frequency of a grating (Experiments 3 and 4). Orthogonally to this, the stimuli were presented either at threshold levels of contrast (Experiments 1 and 3) or at suprathreshold levels (Experiments 2 and 4). Visual field and spatial frequency interacted when the task required identification of spatial frequency, but not when it required only stimulus detection. Regardless of contrast level (threshold, suprathreshold), high-frequency gratings were identified more readily in the right visual field (left hemisphere), whereas low-frequency gratings showed no visual field difference (Experiment 3) or were identified more readily in the left visual field (right hemisphere) (Experiment 4). Thus, hemispheric asymmetries in the processing of spatial frequencies depend on the task. These results support Sergent’s (1982) spatial frequency hypothesis, but only when the computational demands of the task exceed those required for the simple detection of the stimuli. 相似文献

The diagnostic accuracy of the Millon Clinical Multiaxial Inventory (MCMI) computer reports was assessed for the sample of 48 patients reliably identified as having bipolar affective disorder. Only 13 of the 48 reports were accurate in classifying the patients as having bipolar affective disorder, and this was significantly (p < .01) less than 50% of the cases. The diagnostic accuracy clearly left much to be desired. Additional research is needed to assess the validity of MCMI diagnostic suggestions for other patient groups. 相似文献

The use of microcomputers in physiological psychology has allowed many investigators to conduct experiments that previously required more costly devices. We describe some of the research requirements that led to our selection of an Apple II/FIRST microcomputer system (Scandrett & Gormezano, 1980) for investigations of the neurophysiological correlates of classical and instrumental conditioning. 相似文献

Smoking cigarettes and drinking alcohol are positively correlated in cross-sectional studies of the general population. However, it is unclear whether changes in quantity of drinking over time are related to changes in amount of smoking over time. This investigation examined, with structural equation modeling, the relationship of changes in drinking to changes in smoking over 2 years among 344 adults who reported cigarette smoking and alcohol use at baseline in 1989-1990 or at follow-up in 1991-1992 or both. Surprisingly, no significant relationships were found between changes in smoking and changes in drinking. This lack of effect suggests that changes in the quantity or intensity of drinking and of smoking are not related in any important way in nonclinical populations. 相似文献
