Reports were obtained from middle-class and working-class unemployed British men about change or lack of change since job loss in 37 different behaviors. The behaviors were grouped into Domestic Work, Domestic Pastimes, Other Pastimes, Book Reading, Recreations, Entertainment Through Money, and Social Contacts. Contrary to findings from 1930s research, significant increases in social contact and book reading were reported since job loss. Other significant increases were reported within all categories except Entertainment Through Money, where a significant decline was recorded. A number of social class differences were found. For instance, middleclass unemploycd men were significantly more likely than their working-class counterparts to report increased book reading for study and more visits to the public library. Working-class respondents were significantly more likely to report increased looking around shops without buying and reduced visits to the pub. Several significant associations between reported behavior changes and aspects of psychological and general health were observed.  相似文献

In an earlier note, a new metric for bounded response scales (MBR) was introduced which resembles the city-block metric but is bounded above. It was suggested the MBR may be more appropriate than minkowski metrics for data obtained with bounded response scales. In this article, some formal properties of the MBR are investigated and it is shown that it is indeed a metric. Empirical predictions are then derived from the MBR and contrasted with those of a “monotonicity hypothesis,” which holds that dissimilarity judgements tend to be biased towards overestimation of larger distances, and with the predictions of the minkowski metrics, which imply additivity of collinear segments. Some empirical results are presented which contradict the monotonicity hypothesis and the minkowski metrics, and favor the MBR. Finally, the logic used to motivate the MBR is invoked to define a subadditive concatenation for bounded norms in the one-dimensional case, which may be useful in psychophysical work where the upper bounds are often real, rather than due to the response scale. This concatenation predicts understimation for doubling and overestimation for halving and middling tasks.  相似文献

Electrographic (EEG, EOG, EMG) indices have been used for some decades in the definition of the stages of sleep and more recently in the diagnosis of sleep-related disorders, e.g., insomnia, despite the lack of detailed information concerning the precise relationship between such electrographic indices and behavioral and subjective criteria of sleep. Evaluation of the relationship between EEG, behavioral, and self-report measures of sleep onset latency and sleep duration was conducted using 17 young normal sleepers. The behavioral measure was provided by an apparatus which records subjects' button-press responses to an auditory stimulus presented at various interstimulus intervals (2, 5, and random 1, 2, 5, 7, and 10 min). The behavioral and stage 2 EEG estimates of sleep onset latency (SOL) and sleep duration (SD) were almost identical. The stage 1 EEG provided the shortest estimate of SOL; the self-report measure, the longest. The SD measures were in reverse order. There were no significant differences among the three interstimulus interval conditions (2, 5, and random min). Average response rates to the 50-dB chime were 100% during wakefulness, 81% during EEG stage 1, and 8% during EEG stage 2. Almost all stage 2 responding occurred during the first 5 min of each stage 2 period. The validity of electrographic indices as sleep criteria and the implications of the findings for the formulation of an adequate definition of sleep and its clinical measurement are discussed.  相似文献

The Gestalt studies demonstrated the tendency to visually organize dots on the basis of similarity, proximity, and global properties such as closure, good continuation, and symmetry. The particular organization imposed on a collection of dots is thus determined by many factors, some local, some global. We discuss computational reasons for expecting the initial stages of grouping to be achieved by processes with purely local support. In the case of dot patterns, the expectation is that neighboring dots are grouped as a function of proximity and similarity of contrast, by processes that are independent of the overall organization and the various global factors. We describe experiments that suggest a purely local relationship between proximity and brightness similarity in perceptual grouping.  相似文献

Nondeterministic programs occurring in recently developed programming languages define nondeterminate partial functions. Formulas (Boolean expressions) of such nondeterministic languages are interpreted by a nonempty subset of {T (“true”), F (“false”), U (“undefined)}. As a semantic basis for the propositional part of a corresponding nondeterministic three-valued logic we study the notion of a truth-function over {T, F, U} which is computable by a nondeterministic evaluation procedure. The main result is that these truth-functions are precisely the functions satisfying four basic properties, called \( \subseteq \) -isotonic, \( \subseteq \) ?-isotonic, hereditarily guarded, and hereditarily guard-using, and that a function satisfies these properties iff it is explicitly definable (in a certain normal form) from “if..then..else..fi”, binary choice, and constants.  相似文献

Studied the effects of attitude extremity on perceived consensus and willingness to ascribe trait terms to others with either pro or anti nuclear attitudes. Results showed that attitude extremity affected consensus estimates. Trait attributions revealed a clear effect for valence, especially for the extreme attitude groups. Subjects with extreme attitudes also ascribed more traits to both pro and anti others than subjects with relatively moderate attitudes.  相似文献

This article discusses the attenuating mechanisms of group psychotherapy that support and enhance analytic work with borderline patients in combined group and individual psychotherapy. A group case study is presented which addresses the manifestations and management of transference and countertransference in a combined treatment approach. Combined treatment was observed to respond effectively to both the intrapsychic and interpersonal difficulties of borderline patients. A multidimensional model for treating these patients in a community mental health setting is proposed.  相似文献

What speaks louder, false words or false action? Raters assessed the anxiety level of 10 actors portraying their actual anxiety level and simulated displays of high anxiety. Raters were required to base judgments on either video cues alone or audio cues alone. Findings indicate that false words speak louder than false action, with audio-based judgments generating greater judgmental error in both straight and dissembled anxiety conditions. Although raters expressed equal confidence in judgments based on either verbal or nonverbal cues, results indicated that verbal cues played a larger role in emotional deceit. Differences between real and simulated anxiety cues were delineated, suggesting ways of detecting emotional deception. Results were discussed in light of current thought regarding channel contribution in deception.  相似文献

Correlates of work-home role conflict for dual-earner couples were examined. Respondents (N= 208) were an equal number of married, employed men and women with children. Data were collected in the northeastern U.S.A. through a survey which measured work-home role conflict, family climate, domestic responsibilities, and activities performed during one's free time. LISREL was used to determine if domestic responsibilities mediate the correlation between gender and work-home conflict. A regression analysis was used to determine the relative effects of domestic responsibilities and family climate on work-home conflict. Results indicate that (a) work-home role conflict is negatively related to family climate for men as well as for women, (b) gender differences in role conflict are partially attributable to gender differences in domestic responsibilities, and (c) domestic responsibilities and family climate each correlate significantly with work-home role conflict. Findings suggest that how one works hard (the conditions under which one lives) may be just as important as how hard one works (the number of tasks one performs).  相似文献
