This paper examines the consistency of risk preferences across three decision domains important in most people’s lives: work, health and personal finance. We consider the degree to which the five factor model of personality and a range of factors that influence risk-related decision-making (perceived risk, framing, emotions and cost–benefit analysis) impact upon cross-domain consistency. Data were gathered from a sample of participants for whom approaches to risk were likely to vary (academics, chess players, firefighters, mountaineers and City traders). The results showed that participants could be categorised into two groups: those who were consistent in their risk preferences in three decision domains, and those who were inconsistent or domain-specific. The consistent group was significantly lower on neuroticism and higher on agreeableness and conscientiousness with a less variable approach to weighing up the costs and benefits of taking risks than the inconsistent group. The majority of the consistent group was risk averse.When the domain-specific risk preferences of the inconsistent group were examined, data showed that different combinations of personality and decision-making factors predicted risk preferences within each domain.  相似文献

This paper describes a study protocol to investigate the use of immersive virtual reality as a treatment for amputees' phantom limb pain. This work builds upon prior research using mirror box therapy to induce vivid sensations of movement originating from the muscles and joints of amputees' phantom limbs. The present project transposes movements of amputees' anatomical limbs into movements of a virtual limb presented in the phenomenal space of their phantom limb. It is anticipated that the protocol described here will help reduce phantom limb pain.  相似文献

Three studies investigated the importance of movement for the recognition of subtle and intense expressions of emotion. In the first experiment, 36 facial emotion displays were duplicated in three conditions either upright or inverted in orientation. A dynamic condition addressed the perception of motion by using four still frames run together to encapsulate a moving sequence to show the expression emerging from neutral to the subtle emotion. The multi‐static condition contained the same four stills presented in succession, but with a visual noise mask (200 ms) between each frame to disrupt the apparent motion, whilst in the single‐static condition, only the last still image (subtle expression) was presented. Results showed a significant advantage for the dynamic condition, over the single‐ and multi‐static conditions, suggesting that motion signals provide a more accurate and robust mental representation of the expression. A second experiment demonstrated that the advantage of movement was reduced with expressions of a higher intensity, and the results of the third experiment showed that the advantage for the dynamic condition for recognizing subtle emotions was due to the motion signal rather than additional static information contained in the sequence. It is concluded that motion signals associated with the emergence of facial expressions can be a useful cue in the recognition process, especially when the expressions are subtle.  相似文献

Clergy spouses experience various life stressors, yet many cope and function effectively in the midst of their daily challenges. Mental health professionals were asked to identify wives of male clergy who exemplify emotional and spiritual health. Nominees were contacted and interviews conducted with 25 women. Each interviewee was asked about coping with normal life stressors, stressors associated with being married to a minister, and catastrophic life events. All interviews were transcribed and coded, using grounded theory. Participants emphasized the importance of spirituality, social support, limit-setting, and healthy lifestyle choices. Implications are discussed.

Humans and other animals are highly sensitive to deviations from bilateral symmetry and prefer symmetric mates. Fluctuating asymmetries (FAs) are random deviations from perfect symmetry that can result from developmental instability. Human perceptions of facial asymmetry are driven by FAs and insensitive to directional asymmetries (DAs), which have a consistent direction of bias (e.g., left side always larger) across the population and are unrelated to developmental stability. We hypothesized that perceptual adaptation may filter out DAs and provide a proximate mechanism for this perceptual focus on FAs. We created a small population of faces with DAs by applying a unilateral distortion to the same side of each face. After 5 min of adaptation, (new) faces with these DAs looked less asymmetric and the most symmetric-looking distortion shifted toward the adapting asymmetry level. Parallel changes occurred for attractiveness. We suggest that perceptual adaptation may provide the proximate mechanism for an evolutionarily adaptive focus on FAs.  相似文献

This study tested whether a dichotomous thinking style moderates the association of depression with body mass, and investigated the effect of dichotomous thinking and depression on weight loss during a cognitive behavioural therapy (CBT) intervention.Overweight and obese females (n = 76) participated in CBT for weight management for 12 weeks. Before treatment, dichotomous thinking moderated the association of depression with BMI, such that depression was positively associated with BMI among those with low dichotomous thinking, but was not associated among those with high dichotomous thinking. Weight loss was negatively associated with pre-treatment depression and frequency of treatment attendance, but not with dichotomous thinking. Females who regard their weight as unacceptably high and who think dichotomously may experience high levels of depression irrespective of their actual weight, while depression may be proportionate to the degree of obesity among those who do not think dichotomously. Depression, but not dichotomous thinking, is likely to interfere with the ability to adhere to short-term weight loss strategies.  相似文献

Studies of amniotic testosterone in humans suggest that fetal testosterone (fT) is related to specific (but not all) sexually dimorphic aspects of cognition and behaviour. It has also been suggested that autism may be an extreme manifestation of some male‐typical traits, both in terms of cognition and neuroanatomy. In this paper, we examine the possibility of a link between autistic traits and fT levels measured in amniotic fluid during routine amniocentesis. Two instruments measuring number of autistic traits (the Childhood Autism Spectrum Test (CAST) and the Child Autism Spectrum Quotient (AQ‐Child)) were completed by these women about their children (N=235), ages 6–10 years. Intelligence Quotient (IQ) was measured in a subset of these children (N=74). fT levels were positively associated with higher scores on the CAST and AQ‐Child. This relationship was seen within sex as well as when the sexes were combined, suggesting this is an effect of fT rather than of sex per se. No relationships were found between overall IQ and the predictor variables, or between IQ and CAST or AQ‐Child. These findings are consistent with the hypothesis that prenatal androgen exposure is related to children exhibiting more autistic traits. These results need to be followed up in a much larger sample to test if clinical cases of ASC have elevated fT.  相似文献

This study examines the associations between appearance-related, actual-ideal self-discrepancies--from both own and romantic partner's standpoints--and negative affect, body satisfaction, and eating behavior. It extends previous research through studying both genders and the romantic partner standpoint, but its main novel contribution is a systematic comparison between idiographic, participant-generated, and nomothetic, fixed-item measures of appearance-related self-discrepancies. The findings show that these measures cannot be, and should not be, treated as equivalent. The idiographic measures were superior in predicting outcome variables when considering the own standpoint. Nomothetic measures did demonstrate some gender-specific associations, but only from the romantic partner standpoint, and only for women. These findings can be explained with respect to the assessment of accessible, versus available, self-discrepancies. Implications for self-discrepancy and body image theory and research are discussed.  相似文献

Associations between histories of family disruption (residential moves and separations from parent figures) and adolescent adjustment (including educational, internalizing, externalizing, and sexual behavior outcomes) were examined in a random sample of 267 African American girls from 3 urban poverty neighborhoods. Higher numbers of residential moves and parental separations significantly predicted greater adolescent adjustment problems after household demographic characteristics were controlled. Adolescents' perceptions of their current relationships and neighborhoods were significantly associated with adolescent adjustment but did not mediate the effects of family disruption. Associations between parental separations and adolescent outcomes were strongest for externalizing problems and were found for both male and female caregivers, for long-standing and more temporary caregivers, and for separations in early childhood, middle childhood, and adolescence.  相似文献

Although vocabulary acquisition requires children learn names for multiple things, many investigations of word learning mechanisms teach children the name for only one of the objects presented. This is problematic because it is unclear whether children's performance reflects recall of the correct name–object association or simply selection of the only object that was singled out by being the only object named. Children introduced to one novel name may perform at ceiling as they are not required to discriminate on the basis of the name per se, and appear to rapidly learn words following minimal exposure to a single word. We introduced children to four novel objects. For half the children, only one of the objects was named and for the other children, all four objects were named. Only children introduced to one word reliably selected the target object at test. This demonstration highlights the over-simplicity of one-word learning paradigms and the need for a shift in word learning paradigms where more than one word is taught to ensure children disambiguate objects on the basis of their names rather than their degree of salience.  相似文献
