A sample of 440 full-time employed couples from 11 states was examined to determine the differences between time spent on housework by husbands and wives in rural and urban areas. More time is spent in housework in rural families than in urban families because time spent in housework is greater for rural women than for urban women, while rural and urban husbands' times do not differ. Education of spouses, job status differentials, and age of the younger child do not significantly interact with rural-urban residence and sex of the spouse. However, family income does significantly influence the relationship between time spent on housework for rural and urban husbands and wives. 相似文献

The psychophysiological responses of heart rate (HR), systolic and diastolic blood pressure, skin conductance level and forehead electromyogram were compared during: rest, mental arithmetic and combat sounds of gradually increasing intensity for five groups of Ss: Vietnam veterans with post-traumatic stress disorder (PTSD); Vietnam veterans without PTSD but with comparable levels of combat experience; Vietnam veterans with other psychiatric disorders; Vietnam-era veterans; and nonveteran phobics. HR response to low-intensity combat sounds provided good discrimination between veterans with PTSD and the other groups and seems to resemble a conditioned emotional response. 相似文献

The deleterious effects of occupational stress on worker health and well-being have been described in numerous reports for a wide range of work groups. Work overload (and underload), deadline pressures, role Stressors, underutilization of abilities, and physical discomfort have been identified as work factors associated with increased stress symptom reporting. The relationship between work stress and accident/injury occurrences is less clearly documented, although scattered reports in the literature suggest a contributory role for stress in the accident process. In this article, data linking stress to unsafe work behavior are reviewed and a model is proposed wherein accidents can arise from impaired worker capabilities (e.g., slower reaction time) brought about by stress symptom activity (e.g., anxiety). The potential usefulness of stress management training (SMT) for shortcircuiting the stress/accidents cycle by alleviating stress symptoms is discussed in light of recent empirical research.Portions of this article were presented at the Third Annual Scientist/Practitioner Conference in Industrial/Organizational Psychology, Virginia Beach, Virginia, October, 1982. 相似文献

In mixed-modality psychophysical scaling, stimuli from different modalities are presented alternately for judgment on the same scale. The usual purpose is to produce cross-modality matching functions without actually doing cross-modality matches. This paper reports the results of two experiments that extend the method to situations in which the responses, themselves crossmodality matches on an easy-to-control continuum (duration), are used to derive matching functions for two difficult-to-control continua (here loudness and brightness). Derived cross-modality matching functions are highly similar to those obtained from magnitude estimation or category judgment responses. First- and second-order sequential dependencies also closely resemble those found in data from the methods that employ numerical response scales, with one exception. For the first time in these studies of mixed-modality scaling, current responses sometimes were found to be weakly contrasted to the values of previous stimuli of different modality from the current stimulus. The various sequential dependencies found may arise from different levels of processing, with intramodal response-stimulus contrast arising from sensory differentiation, inter- and intramodality response-response assimilation from perceptual categorization processes, and intermodality response-stimulus contrast from cognitive expectancies. 相似文献

Elementary school children between the ages of eight and thirteen were administered the Children's Nowicki/Strickland Locus of Control Scale annually for three years. As predicted, children's mean locus of control scores were found to be significantly different from one age group to the next (cross-sectional analysis) as well as from one year to the next (longitudinal analysis). Older children had significantly more internal scores than did younger children, and the same 97 children demonstrated significant increases in internal perceptions over each succeeding year. No significant sex differences were observed in this generally linear developmental trend. The study supports the hypothesis that increases in internal perceptions are associated with growing older. The data are explained using a confluent theoretical perspective drawing upon cognitive as well as behavioral theory. 相似文献

Average evoked brain responses were computed from four simultaneous recordings during binaural tone stimulation at 10 intensity levels. Amplitudes and latencies were measured for the prominent components, and linear regression coefficients were computed. The results indicate that the sensitivity of the evoked response to stimulus intensity is dependent upon the selection of the appropriate measure. Linear amplitude functions were demonstrated. Additional research relating these responses to psychophysical measures is suggested. 相似文献

A noise generator that is capable of delivering long-duration samples of reproducible noise is described. The noise is generated as a pseudorandom telegraph waveform but may be filtered so that its amplitude distribution is approximately Gaussian. The design and construction of the generator are detailed and a few possible applications are given. 相似文献
