Factor analyses were carried out on the responses of 115 cigarette smokers to the Smoking Questionnaire of Russell et al. (1974), to the Situational Smoking Questionnaire of Frith (1971) and to certain items of a biographical smoking questionnaire. In the analysis of Russell's questionnaire, a set of six factors was extracted, bearing some resemblance to the six factors found by the authors of the questionnaire, although the matching of factors was by no means perfect. However, the results did support Russell et al.'s finding of a major dimension of degree of dependence upon cigarettes, together with an orthogonal factor contrasting pharmacological with non-pharmacological dependence. The analysis of the Situational Smoking Questionnaire confirmed Frith's finding that the first principal component represented a general desire for cigarettes while the second contrasted desire to smoke in high- and low-arousal inducing (or stressful and relaxing) situations; and these two components corresponded fairly well with the first two components extracted from Russell's questionnaire, pharmacological dependence being associated with smoking in stressful situations. 相似文献

An adaptive psychometric procedure that places each trial at the current most probable Bayesian estimate of threshold is described. The procedure takes advantage of the common finding that the human psychometric function is invariant in form when expressed as a function of log intensity. The procedure is simple, fast, and efficient, and may be easily implemented on any computer. 相似文献

Previous research has suggested that left-handedness relates to delinquency and violence. In an effort to pinpoint the nature of this apparent relationship, we compared the MMPIs of 72 left- and 687 right-handed men 60 yr. old or less on an alcohol treatment ward. No significant differences appeared. The results are compared to earlier research and hypotheses for further research are suggested. 相似文献

Tripartite model of anxiety and depression: psychometric evidence and taxonomic implications 总被引:58,自引:0,他引:58
We review psychometric and other evidence relevant to mixed anxiety-depression. Properties of anxiety and depression measures, including the convergent and discriminant validity of self- and clinical ratings, and interrater reliability, are examined in patient and normal samples. Results suggest that anxiety and depression can be reliably and validly assessed; moreover, although these disorders share a substantial component of general affective distress, they can be differentiated on the basis of factors specific to each syndrome. We also review evidence for these specific factors, examining the influence of context and scale content on ratings, factor analytic studies, and the role of low positive affect in depression. With these data, we argue for a tripartite structure consisting of general distress, physiological hyperarousal (specific anxiety), and anhedonia (specific depression), and we propose a diagnosis of mixed anxiety-depression. 相似文献

A single-subject experimental design was used to investigate the feasibility of applying non-invasive laboratory instrumentation for examining speech physiology to assessment and biofeedback-based remediation of stuttering. Physiologic assessment facilitated the development of behavioral goals directed at changing respiratory and phonatory behaviors for this subject. Visual biofeedback therapy produced reduction in respiratory discontinuities and increased phonatory continuity, concomitant with reduced perceivable molar dysfluency. Methods used in this case illustrate a variety of options and problems related to clinical use of instrumentation. Results suggest that signals which represent respiratory, phonatory, and articulatory physiologic events may be clinically practical for evaluating and altering perceivable dysfluency. 相似文献

An 8-month-old infant with a developmental quotient of months was given response-contingent stimulation using a pressure-sensitive pillow which turned an overhead mobile. The subject learned to control the mobile by kicking the pillow, and concurrently began smiling at both the mobile and her mother for the first time. After mastering three contingencies on arm, head, and leg movement, she displayed what appeared to be a Piagetian coordinated secondary circular reaction, in which one response provided 4 seconds of access to another contingency. Although the subject remains severely retarded, the results suggest that some forms of developmental delay may be treated at least in part as a failure to develop contingency awareness. 相似文献

Thirty-two infants aged 14 and 20 weeks were presented with a live face in each of eight conditions, which consisted of all combinations of (a) a 0° or 90° orientation; (b) familiar face (the infant's mother) or distinctively unfamiliar face; and (c) talking or silent context. The previous findings that younger infants smile longer at 0° than at 90° faces and that this differential responsiveness to orientation wanes with increasing age were replicated; the hypothesis that older infants would smile longest at their mothers' talking faces in the 0° orientation was confirmed. In addition, infants of both ages smiled more at their mothers than at the stranger, although this effect interacted with orientation and sex of the infant. 相似文献

Two studies were conducted to examine whether attributions made about events may be influenced by individual assumptions regarding causation that are age related. In Study 1, 96 subjects at three age levels (four and five years, eight and nine years, and college students) observed a target actor on videotape select an item from an unseen array, and four other actors either agree (high consensus) or disagree (low consensus) with the choice. Subjects were asked to decide why the actor liked the chosen object best—because of something about the actor (person attribution) or because of something about the item (entity attribution). The results showed that perceived locus of causality shifted from entity to person attributions with age. In addition, subjects at all ages were able to utilize the consensus information when they had no opportunity to form their own impressions about the items in the array. In Study 2, 126 subjects at four age levels (five and six years, seven and eight years, nine and ten years, and high school students) chose an item from among an array for themselves and responded to a person (self)/entity attribution question regarding the locus of their own choice. The entity to person shift with age was again found and was supported by additional measures. The results are discussed in terms of children's causal reasoning capacities and social environmental factors affecting developmental change in social judgments. 相似文献
