Barrett, Rapee, Dadds, and Ryan (1996) described a phenomenon whereby family discussions magnified the style of children's problem solving in a way characteristic of their particular clinical diagnosis. That is, anxious children became more avoidant, aggressive children more aggressive, and nonclinic children more prosocial, after discussing ambiguous hypothetical situations with their parents. This study examined specific sequences of communications exchanged between parents and children hypothesized to underlie this family exacerbation of child cognitive style. Family discussions were videotaped and categorized for groups of anxious, aggressive, and nonclinic children and their parents. Results revealed differences between groups of parents in frequency of agreeing with and listening to their child and the frequency of pointing out positive consequences. Conditional probability analyses showed that parents of anxious children were more likely to reciprocate avoidance, while parents of nonclinic children were more likely to agree with and listen to prosocial plans from their child. Differences in parent behaviors observed during the family discussions were reliably associated with the child's response to the ambiguous situation proposed after the family discussion. Results support a model of developmental anxiety and aggression that emphasizes the interaction of family processes and social-cognitive development in the child.This research was supported by grants from The National Health and Medical Research Council of Australia, The University of Queensland, and The Myer Foundation of Australia. 相似文献

The relationships of coping strategies with levels of substance use and sexual activity, and with HIV sexual risks, are examined in a sample of gay male STD clinic patients (n = 416). Previous research has suggested that use of problem-focused coping strategies should be negatively related to levels of substance use, levels of sexual activity, and HIV sexual risks; use of emotion-focused coping strategies should be positively related to these outcomes. It is argued that substance use and sexual activity clearly fit within a coping perspective, but that the HIV sexual risks/coping relationship is less clear. In multivariate analysis, the problem-focused strategy of advice seeking is negatively related to the number of types of drugs used and to the number of sexual partners; the problem-focused strategy of support seeking is negatively related to the number of days using drugs; and the use of emotion-focused strategies is positively related to the number of types of drugs used. Problem-focused coping strategies are less directly related to engaging in HIV sexual risks when measures of substance use and of sexual activity are included in the prediction; emotion-focused coping strategies are more stably related to HIV risk. Indirect effects of coping on HIV risk are also identified through the effects of coping on the number of types of drugs used, number of sex partners, and number of times having sex. It is proposed that the relationships between coping and levels of substance use and sexual activity reflect the use of these activities as ways of relieving strain, but that relationships between coping and HIV sexual risks involve less clearly understood direct and indirect relationships. 相似文献

Previous research has found that test takers can score above chance level on reading comprehension tests even when the passages are omitted. The present research investigated whether the effect would vary as a function of race. In Study 1, 386 participants completed a reading test with the passages omitted. General mental ability and race were significantly correlated with test performance. In Study 2, 827 job applicants completed the test as part of an entry-level selection battery. Eliminating items for which large race differences existed in Study 1 had no real effect on the size of the Black-White mean difference. 相似文献

When viewing a pair of bars defined by the difference of spatial Gaussian functions (DOGs), human observers can discriminate accurately the relative movements of the bars, even when they differ in spatial frequency. On each trial, observers viewed two brief presentation intervals in which a pair of vertically oriented DOGs moved randomly back and forth within a restricted range. During one interval, both bars moved in the same horizontal direction and by the same magnitude (correlated movements); in the other interval, their movements were uncorrelated. When discrimination accuracy is related to the simultaneous detection of two independent movements, it was found that, if observers can detect the movements of spatially separated bars, they can tell whether their relative movements are correlated. Performance remained remarkably accurate even when the two bars differed in spatial frequency by more than two octaves or were presented separately to the two eyes. Apparently, the accurate discrimination of coherent motion involves an efficient spatial integration of optical motion information over multiple spatial locations and multiple spatial scales. 相似文献

This paper reviews the research literature on MMPI assessment of functional versus organic low back pain (LBP). Research is described in three categories: (a) the relationship between psychopathology as measured by the MMPI and low back pain, (b) MMPI speciality scales, and (c) surgical outcomes. Research, to date, has suffered from methodological problems which has limited generalizations to clinical population. It is suggested, however, that the MMPI can be effectively used with LBP patients, but should not be the only data used in such assessments. Cautions are noted regarding use of the speciality scales. 相似文献

Response suppression by visual stimuli paired with postsession d-amphetamine injections in the pigeon 总被引:1,自引:1,他引:0 下载免费PDF全文
Responding of pigeons, maintained under a fixed-interval 3-minute schedule of food presentation, was decreased on days that the color of the lights illuminating the food magazine was changed and d-amphetamine (1.0 mg/kg, i.m.) was injected after the session. Responding was not decreased by keylight color changes paired with postsession d-amphetamine or by postsession injections of saline. Administration of pentobarbital (3.0 to 5.6 mg/kg), but not d-amphetamine (.3 to 3.0 mg/kg), before the session increased rates of responding suppressed by drug-paired magazine lights. Responding maintained under a fixed-ratio 30-response schedule was not decreased when differently colored magazine lights were paired with a low (.3 mg/kg) postsession dose of d-amphetamine; with high (3.0 mg/kg) postsession doses, however, responding was completely suppressed after two pairings. The effects of pairing magazine stimuli with an intermediate (1.0 mg/kg) postsession dose of d-amphetamine depended upon the magnitude of prior postsession doses. After being paired with a low dose, stimuli paired with 1.0 mg/kg did not suppress responding. After being paired with a high dose, stimuli paired with 1.0 mg/kg completely suppressed responding. The suppression of food-maintained responding by stimuli paired with postsession drug administration depends upon both behavioral and pharmacological variables. 相似文献

Previous research has suggested that questions eliciting visual imagery are associated with lower rates of saccadic eye movements as compared to questions eliciting verbal processes. Two experiments reported here examined the roles of external visual stimulation and speech output in this effect. In both experiments, questions designed to elicit verbal-linguistic or visual-imaginal processing, and which required either syntactically complex or simple responses, were administered while eye movements were recorded by electrooculography. In experiment 1, 42 subjects responded while viewing either the interviewer's face or a gray oval on a video monitor. Imaginal questions elicited a lower rate of eye movements than did verbal questions regardless of the display on the monitor. In experiment 2, 17 subjects responded in conditions of light and darkness. Imaginal questions elicited lower rates of eye movements in both light and dark. Neither cognitive mode nor speech output requirements interacted with stimulus conditions in either experiment. The failure of visual conditions to influence the verbal-imaginal difference in eye movement rate is viewed as inconsistent with a visual interference interpretation of the relationship of eye movements to cognitive activity. Alternate interpretations are discussed. 相似文献

Conjunctive schedules of reinforcement II: response requirements and stimulus effects 总被引:3,自引:3,他引:0 下载免费PDF全文
Barrett JE 《Journal of the experimental analysis of behavior》1975,24(1):23-31
Responding of three pigeons was maintained under conjunctive fixed-ratio, fixed-interval schedules where a key peck produced food after both schedule requirements were completed. The individual schedule requirements were then successively removed and reinstated with responding maintained under the following conditions: conjunctive fixed-ratio, fixed-time; fixed-time; and fixed-interval schedules. Patterns of responding changed in accord with the successive removal of the schedule requirements. Compared to the conjunctive fixed-ratio, fixed-interval schedule, pause duration increased and response rate decreased under conjunctive fixed-ratio, fixed-time schedules and under fixed-time schedules alone. Overall mean rates of responding were highest and pause duration lowest under fixed-interval schedules. When changes in the keylight colors were correlated with completion of the fixed-ratio, the end of the fixed-interval, or both of these conditions, the pattern of responding was modified and indicated a greater degree of control by the individual schedules. Although two birds showed large increases in interreinforcement time when they were initially exposed to the conjunctive schedule, when responding stabilized this measure was largely invariant for all birds across most schedule conditions. 相似文献
