The nature of cognitive deficits in obsessive‐compulsive disorder (OCD) is characterized by contradictory findings in terms of specific neuropsychological deficits. Selective impairments have been suggested to involve visuospatial memory, set shifting, decision‐making and response inhibition. The aim of this study was to investigate cognitive deficits in decision‐making and executive functioning in OCD. It was hypothesized that the OCD patients would be less accurate in their responses compared to the healthy controls in rational decision‐making on a version of the Cambridge gambling task (CGT) and on the color‐word interference test and on a version of the Tower of Hanoi test (tower test) of executive functioning. Thirteen participants with OCD were compared to a group of healthy controls (n = 13) matched for age, gender, education and verbal IQ. Results revealed significant differences between the OCD group and the healthy control group on quality of decision‐making on the CGT and for achievement score on the tower test. On these two tasks the OCD group performed worse than the healthy control group. The symptom‐dimension analysis revealed performance differences where safety checking patients were impaired on the tower test compared to contamination patients. Results are discussed in the framework of cognition and emotion processing and findings implicate that OCD models should address, specifically, the interaction between cognition and emotion. Here the emotional disruption hypothesis is forwarded to account for the dysfunctional behaviors in OCD. Further implications regarding methodological and inhibitory factors affecting cognitive information processing are highlighted. 相似文献

The Childhood Trauma Questionnaire ‐ Short Form (CTQ‐SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out‐of‐home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five‐factor structure of the CTQ‐SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ‐SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma. 相似文献

As with standard models of rationality, theorists generally treat prospect theory's demonstration of risk aversion in gains but risk tolerance in losses as domain‐general. Yet evolutionary psychology suggests that natural selection has designed a domain specific cognitive architecture—with systems specialized for some substantive domains but not others. Here we address risky choices through that lens asking whether humans' risk responses dispose them to enter social relationships even when doing so is counter to normative rationality and regardless of whether the “enter” versus “not enter” choice is framed as between gains and losses. Laboratory findings in five sites across three countries provide a positive answer to both possibilities. Participants could enter or not enter inherently risky social relationships. They were more willing to enter such relationships than rational choice models would predict and were equally so willing regardless of whether equivalent alternatives were framed as gains and as losses. With the “social context” extracted in otherwise identical games, participants' risk responses were consistent with prospect theory. The present findings suggest the possibility of adaptations designed to facilitate sociality—despite its risks and how those risks are framed. 相似文献

This study aimed to extricate the influence of rational (e.g. ‘I think …’) and intuitive (e.g. ‘I feel …’) probability beliefs in the behavioural decision-making process regarding skin cancer prevention practices. Structural equation modelling was used in two longitudinal surveys (sun protection during winter sports [N?=?491]; sun protection during summer [N?=?277]) to examine direct and indirect behavioural effects of affective and cognitive likelihood (i.e. unmediated or mediated by intention), controlled for attitude, social influence and self-efficacy. Affective likelihood was directly related to sun protection in both studies, whereas no direct effects were found for cognitive likelihood. After accounting for past sun protective behaviour, affective likelihood was only directly related to sun protection in Study 1. No support was found for the indirect effects of affective and cognitive likelihood through intention. The findings underscore the importance of feelings of (cancer) risk in the decision-making process and should be acknowledged by health behaviour theories and risk communication practices. Suggestions for future research are discussed. 相似文献

Local comparisons with a few people displace the influence of general comparisons with many people during self-evaluation of performance and ability. The current research examined whether this local dominance effect obtains in the domain of health risk perception, an outcome of critical importance given its direct relation to preventative health behaviours. Participants received manipulated feedback indicating that their risk of diabetes (Study 1) or a serious car accident (Study 2) ranked above average or below average relative to numerous peers. Additionally, some participants were told that their risk ranked highest or lowest relative to a few peers. Participants evaluated their risk as significantly higher when they only knew that it ranked above average than below average. However, this effect was eliminated among participants who received additional local comparison information. These findings highlight the potential biasing influence of local comparison on everyday health judgment and behaviour. 相似文献

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction. 相似文献

Research examining smokers’ understanding of their smoking risk reveals that smokers acknowledge some risk but often deny or minimize personal risk. We examined risk perceptions of lung cancer among smokers and non-smokers in a smoking-lenient (Denmark) and a smoking-prohibitive (the United States) culture. Participants were 275 Danish students attending trade schools (mean age 22.6 years) and 297 US students attending community colleges in Florida (mean age 23.6 years). Results revealed cross-cultural differences suggesting that Danish smokers showed greater risk minimization than US smokers. In addition, in both countries the risk of a typical smoker was rated as lower by smokers than non-smokers, and smokers rated their personal risk as lower than they rated the risk of the typical smoker. Cross-cultural differences in moralization of smoking might be one explanation for these findings. 相似文献

Abstract The role of work characteristics in determining return to work after an acute coronary event was examined. One hundred and forty nine patients were enrolled. One year post-discharge, 74 had returned to work. Work characteristics (decision latitude, and opportunity for social interaction at work), together with age, depression, and medical prognosis, correctly classified work status in 78% of cases. At 12 months post-discharge, patients who had not returned to work recorded significantly poorer levels of adjustment compared to those who had returned to work. A better quality of life is associated with a lower level of depression pre-hospitalization, ownership of a larger home, being male, and having a more positive work environment. The findings suggest that the pre-illness work environment of the patient is a factor influencing return to work, which needs to be considered in rehabilitation programmes. 相似文献

Abstract This paper is a response to Eiser's (1996) call for a unifying theoretical perspective that would bridge the gap between 'individualistic and ‘social’ approaches to studying human social behaviour in general, and health behaviour in particular. While agreeing with Eiser's premise that it makes no sense to study cognition, affect, and behaviour independently of social context, the present paper takes issue with certain features of his argument that a connectionist approach provides the needed unifying theoretical framework. It is suggested that if connectionism can describe the psychological processes underlying social behavior better than non-connectionist theories, this would provide more compelling evidence of its value than claims that it affords new theoretical insights. 相似文献
