Abstract

Reactivity to observation can affect both internal and external validity of experimental studies. Although the effects of observation have been well documented in groups and parent-child interaction, there have been few studies of observer effects on couples. This study assessed the effects of three different methods of observation—one-way mirror, audio-recording and video-recording—on 30 volunteer, nonclinical couples. No differences were found among couples in the three observational conditions on measures of interactional behavior on a problem-solving task, participant appraisals of self-consciousness, discomfort and reactivity for themselves and their spouses, or on pre-post observation measures of anxiety and feelings toward spouse. The results suggest that these different types of observation do not produce significantly different effects on nonclinical couples and that studies utilizing these three methods may be compared.  相似文献

Abstract

This paper presents a study of a structural couple therapy approach to the treatment of inhibited sexual desire (ISD). ISD is first conceptualized as a relational phenomenon that may be most effectively treated in a couple context. Structural couple therapy is advanced and applied to the treatment of a clinical sample of couples presenting with ISD. Results of the study suggest that a structural couple therapy approach to ISD is effective in reducing symptoms of the sexual disorder and in increasing couple satisfaction.  相似文献

Vignette and autobiographical recall studies have often been used to test models of the appraisals associated with specific emotions. Recently, critiques of both methodologies have called into question the applicability of appraisal theory to naturally-occurring emotional responses. This study examined supporter's responses to Ross Perot's withdrawal from the 1992 presidential race to assess the extent to which appraisal models accurately capture responses to a naturally-occurring event. Supporters in Riverside County, California (N = 227) completed questionnaires concerning their interpretations of the event, their initial emotional reactions, changes in their reactions in the weeks immediately following Perot's withdrawal, and their plans. Appraisal models correctly predicted the dimensions of agency and coping potential that served to differentiate sadness from anger, and the appraisals and plans associated with hope. Appraisal models did not predict the strong focus of sad supporters on their past goals and beliefs, and the plans associated with sadness and anger. Changes in emotional intensity occurred as a function of changes in goals and plans rather than merely as a function of time. These findings demonstrate the applicability of appraisal theory to naturally-occurring emotional responses, but also show that models may understate the complexity of the planning processes associated with emotions.  相似文献

This study employed an immersed virtual environment (IVE) in the Nijmegen RIVERlab to study spider fearfuls’ attentional and motor reactions to virtual spiders. The participants were exposed to virtual spiders while completing an unrelated task, walking freely through a virtual museum. Compared to non-fearful controls, spider fearfuls showed an increase in state anxiety, they spent more time looking at spiders, and they exhibited spontaneous behavioural avoidance of spiders and visually similar objects. The results extend, and to some degree contradict, those of earlier studies with static pictures, and they speak to the usefulness of state-of-the-art IVEs in fundamental anxiety research.  相似文献

This study describes six first-grade students’ use of metacognitive strategies. The students (4 boys and 2 girls) represented low, average, and above-average readers and were enrolled in a rural Midwestern elementary school. A variety of data were collected throughout the year: (a) an informal reading inventory and metacognitive awareness interview were conducted at the beginning and end of the year; and (b) during the school year, think-aloud interview protocols, running records, anecdotal notes, and retellings were conducted. The analysis revealed that these first graders were reporting and using a variety of strategies to read.  相似文献

Bacterial meningitis is a life threatening infection of the central nervous system. This illness is most prevalent early in life when the healthy child is rapidly acquiring language. This study investigated whether children with a history of bacterial meningitis were at risk for language difficulties post illness. Thirty post-meningitic children, aged between 9 years 0 months and 11 years 0 months, participated in this study. Each subject was administered a measure of non-verbal cognitive ability and a range of language tasks. These children performed poorly on applied language tasks, which tap skills used in effective discourse. These deficits occurred despite age appropriate performances on measures of linguistic/grammatical knowledge. These findings clearly illustrate that bacterial meningitis has implications for ongoing language development, which emphasises the importance of long term follow up. In developmental terms, this discrepancy between verbal knowledge and problem solving represents a dissociation between language skills which develop early in life and those which emerge later. This pattern of results suggests that bacterial meningitis may result in a delay in language development. A young age at illness was identified as an additional risk factor for adverse outcome. This study highlights the need to inform parents/guardians that post-meningitic children are at risk for experiencing language difficulties throughout childhood.  相似文献

This article provides a reanalysis of J. W. Johnson's (2000) “relative weights” method for assessing variable importance in multiple regression. The primary conclusion of the reanalysis is that the derivation of the method is theoretically flawed and has no more validity than the discredited method of Green, Carroll, and DeSarbo (1978) on which it is based. By means of 2 examples, supplemented by other results from the literature, it is also shown that the method can result in materially distorted inferences when it is compared with another widely used importance metric, namely, general dominance (Azen & Budescu, 2003; Budescu, 1993). Our primary recommendation is that J. W. Johnson's (2000) relative weights method should no longer be used as a variable importance metric for multiple linear regression. In the final section of the article, 2 additional recommendations are made based on our analysis, examples, and discussion.  相似文献

Cross‐situational word learning, like any statistical learning problem, involves tracking the regularities in the environment. However, the information that learners pick up from these regularities is dependent on their learning mechanism. This article investigates the role of one type of mechanism in statistical word learning: competition. Competitive mechanisms would allow learners to find the signal in noisy input and would help to explain the speed with which learners succeed in statistical learning tasks. Because cross‐situational word learning provides information at multiple scales—both within and across trials/situations—learners could implement competition at either or both of these scales. A series of four experiments demonstrate that cross‐situational learning involves competition at both levels of scale, and that these mechanisms interact to support rapid learning. The impact of both of these mechanisms is considered from the perspective of a process‐level understanding of cross‐situational learning.  相似文献

Abstract

Recent investigations suggest that the hostility component of the Type A behavior patter (TABP) is a greater detriment to health than the overall pattern. Some researchers suggest that certain Type A characteristics (e.g., job-involvement) are actually adaptive. This study compared the relative relationship of the TABP and hostility to career-related achievement and psychosocial adjustment among 223 service-delivery employees. Male and female participants completed the Jenkins Activity Survey and the MMPI Hostility Scale as part of a cardiovascular disease risk factor screening. The TABP was positively associated with managerial status for both men and women. However, the TABP was positively related to psychosocial adjustment variables among men only. Hostility was significantly related to undesirable outcomes including lower job status, life dissatisfaction, and unfavorable perceptions of the workplace for both men and women. Discussion addresses organizational factors which might perpetuate hostility and the TABP, as well as gender differences in the experience of these constructs.  相似文献

This study assessed the unique associations of risk perceptions and worry with attitudes about genetic testing for breast cancer susceptibility. Women (general practitioner clinic attenders, university students, and first-degree relatives of breast cancer survivors; N?=?303) read information about genetic testing and completed measures assessing perceived cancer risk, cancer worry, and genetic testing attitudes and beliefs. Worry was associated with greater interest in genetic testing, stronger beliefs that testing has detrimental emotional consequences, and positive beliefs about benefits of testing and risk-reducing surgeries. Perceived risk was unrelated to interest and associated with more skeptical beliefs about emotional consequences and benefits of testing and risk-reducing surgeries. At low worry levels, testing interest increased with more positive beliefs about testing benefits; at high worry levels, interest was high regardless of benefits beliefs. The findings support Leventhal's Common-Sense Model of self-regulation delineating interactive influences of risk-related cognitions and emotions on information processing and behavior.  相似文献
