Cystic fibrosis (CF) is the most common recessive condition affecting the White British population. Facilitating reproductive decision making for couples at genetic risk for CF is an important aspect of genetic counseling practice in the UK. The purpose of this study was to explore the reproductive decision making process for 31 members of CF carrier couples (15 men and 16 women) with or without an affected child. The design involved a qualitative approach consisting of semi-structured interviews and data analysis informed by grounded theory methodology. Sex and personal experience of CF were identified as factors that may influence reproductive decision making. Findings suggest these hypotheses: (1) CF carrier couples who have an affected child/pregnancy, are more likely to embark on another pregnancy than couples who have a healthy child from an at-risk pregnancy, and (2) men and women play different roles in the reproductive decision making process. Data analysis resulted in development of a structured framework modeling the reproductive decision making process, which may be helpful in guiding genetic counseling with CF carrier couples and other at risk couples making reproductive decisions.  相似文献

The present study examined the causal role of amount of Black ancestry in targets' perceived fit with Black prototypes and perceivers' categorization of biracial targets. Greater Black ancestry increased the likelihood that perceivers categorized biracial targets as Black and perceived targets as fitting Black prototypes (e.g., experiencing racial discrimination, possessing stereotypic traits). These results persisted, controlling for perceptions of phenotype that stem from ancestry information. Perceivers' beliefs about how society would categorize the biracial targets predicted perceptions of discrimination, whereas perceivers' beliefs about the targets' self-categorization predicted trait perceptions. The results of this study support the Black ancestry prototype model of affirmative action, which reveals the downstream consequences of Black ancestry for the distribution of minority resources (e.g., affirmative action) to biracial targets.  相似文献

The maintenance of self-reported quality of life (QL) among people on the liver transplantation waiting list is one of the priority objectives of transplantation teams. Although there are different determinant factors of QL, results are not conclusive. In our study, the goal was to evaluate both the influence of cirrhosis etiology (ethylic and non-ethylic) and the coping strategies used concerning QL. A sample of 93 patients was selected, divided into two groups: ethylic cirrhosis (EC) and non-ethylic cirrhosis (NEC). QL was evaluated through the SF-36 Health Survey, and coping strategies through the Medical Coping Modes Questionnaire (MCMQ). Our results indicated that subjects with EC obtained similar QL levels to subjects with NEC, on all the SF-36 and MCMQ subscales. Furthermore, negative correlations were found between avoidance and acceptance-resignation coping strategies with the SF-36 components. Consequently, the acceptance-resignation strategy was associated with a worse perception of physical functioning, general and mental health, and vitality and role-emotional. Overall, these results suggest that cirrhosis etiology is not a determinant factor of QL, whereas the acceptance-resignation coping strategy might lead to lower self-perception of QL.  相似文献

Malt liquor (ML) is a unique, high alcohol content beverage marketed to encourage heavy drinking. We developed the Malt Liquor Expectancy Questionnaire (MLEQ), a beverage-specific measure of alcohol expectancies, and examined its association with typical weekly ML use, typical weekly alcohol use, and alcohol problems. Forty positive and 40 negative expectancy items were administered to a sample of 639 young adults who regularly consumed ML. Exploratory and confirmatory factor analyses led to the development of the 30-item MLEQ. The MLEQ consists of two positive (i.e., Social Facilitation and Enjoyment, Enhanced Sexuality) and two negative factors (i.e., Aggression and Negative Consequences; Impairment and Physical Symptoms) that possess good internal consistency, test-retest reliability, and convergent validity. The psychometrically sound MLEQ contributes to the limited research on beverage-specific expectancies and heavy drinking.  相似文献

How can we understand the uses of music in daily life? Music is a universal phenomenon but with significant interindividual and cultural variability. Listeners’ gender and cultural background may influence how and why music is used in daily life. This paper reports the first investigation of a holistic framework and a new measure of music functions (RESPECT‐music) across genders and six diverse cultural samples (students from Germany, Kenya, Mexico, New Zealand, Philippines, and Turkey). Two dimensions underlie the mental representation of music functions. First, music can be used for contemplation or affective functions. Second, music can serve intrapersonal, social, and sociocultural functions. Results reveal that gender differences occur for affective functions, indicating that female listeners use music more for affective functions, i.e., emotional expression, dancing, and cultural identity. Country differences are moderate for social functions (values, social bonding, dancing) and strongest for sociocultural function (cultural identity, family bonding, political attitudes). Cultural values, such as individualism–collectivism and secularism–traditionalism, can help explain cross‐cultural differences in the uses of music. Listeners from more collectivistic cultures use music more frequently for expressing values and cultural identity. Listeners from more secular and individualistic cultures like to dance more. Listeners from more traditional cultures use music more for expressing values and cultural identity, and they bond more frequently with their families over music. The two dimensions of musical functions seem systematically underpinned by listeners’ gender and cultural background. We discuss the uses of music as behavioral expressions of affective and contemplative as well as personal, social, and sociocultural aspects in terms of affect proneness and cultural values.  相似文献

When attention is oriented to a peripheral visual event, observers respond faster to stimuli presented at a cued location than at an uncued location. Following initial reaction time facilitation responses are slower to stimuli subsequently displayed at the cued location, an effect known as inhibition of return (IOR). Both facilitatory and inhibitory effects have been extensively investigated in two-dimensional space. Facilitation has also been documented in three-dimensional space, however the presence of IOR in 3D space is unclear, possibly because IOR has not been evaluated in an empty 3D space. Determining if IOR is sensitive to the depth plane of stimuli or if only their bi-dimensional location is inhibited may clarify the nature of the IOR. To address this issue, we used an attentional cueing paradigm in three-dimensional (3D) space. Results were obtained from fourteen participants showed IOR components in 3D space when binocular disparity was used to induce depth. We conclude that attentional orienting in depth operates as efficiently as in the bi-dimensional space.  相似文献

The study of sleep deprivation is a fruitful area of research to increase our knowledge of cognitive functions and their neural basis. In the current work, 26 healthy young adults participated in a sleep deprivation study, in which the Attentional Networks Test for Interactions and Vigilance (ANTI-V) was performed at 10a.m. after a night of normal sleep and again at 10 a.m. after 25.5-27.5 h of total sleep deprivation. The ANTI-V is an experimental task that provides measures of alerting, orienting and executive control attentional functions. Compared with previous versions, the ANTI-V includes a vigilance task, more reliable auditory alerting signals, non-predictive peripheral orienting cues, and also a neutral no-cue condition allowing the analysis of reorienting costs and orienting benefits. Thus, new evidence to evaluate the influence of sleep deprivation on attentional functioning is provided. Results revealed differences in both tonic and phasic alertness after sleep deprivation. Vigilance performance was deteriorated, while a warning tone was more helpful to increase participants' alertness, resulting in slightly faster RT and, in particular, fewer errors. The reorienting costs of having an invalid spatial cue were reduced after sleep loss. No sleep deprivation effect on the executive control measure was found in this study. Finally, since no control group was used, particular precautions were taken to reduce the influence of potential practice effects.  相似文献

The current research examines the effects of time pressure on decision behavior based on a prospect theory framework. In Experiments 1 and 2, participants estimated certainty equivalents for binary gains-only bets in the presence or absence of time pressure. In Experiment 3, participants assessed comparable bets that were framed as losses. Data were modeled to establish psychological mechanisms underlying decision behavior. In Experiments 1 and 2, time pressure led to increased risk attractiveness, but no significant differences emerged in either probability discriminability or outcome utility. In Experiment 3, time pressure reduced probability discriminability, which was coupled with severe risk-seeking behavior for both conditions in the domain of losses. No significant effects of control over outcomes were observed. Results provide qualified support for theories that suggest increased risk-seeking for gains under time pressure.  相似文献
