Medical advances have resulted in increased survival rates for children with brain tumors. Consequently, issues related to survivorship have become more critical. The use of multimodal treatment, in particular cranial radiation therapy, has been associated with subsequent cognitive decline. Specifically, deficits in executive functions have been reported in survivors of various types of pediatric brain tumor. Survivors are left with difficulties, particularly in self-monitoring, initiation, inhibition, and planning, to name a few. Another domain in which survivors of pediatric brain tumor have been reported to show difficulty is that of social skills. Parents, teachers, and survivors themselves have reported decreased social functioning following treatment. Deficits in executive functions and social skills are likely interrelated in this population, as executive skills are needed to navigate various aspects of social interaction; however, this has yet to be studied empirically. Twenty-four survivors of pediatric brain tumor were assessed using a computerized task of executive functions, as well as paper-and-pencil measures of social skills and real-world executive skills. Social functioning was related to a specific aspect of executive functions, that is, the survivors' variability in response time, such that inconsistent responding was associated with better parent-reported and survivor-reported social skills, independent of intellectual abilities. Additionally, parent-reported real-world global executive abilities predicted parent-reported social skills. The implications of these findings for social skills interventions and future research are discussed. 相似文献

Abstract Berry's (1997) framework for acculturation research was used to explore the relationship between identity and health among Irish immigrants in England. One hundred and twelve first generation Irish immigrants completed questionnaire measures of ethnic identity, opportunities for identity expression, generalised coping style, and health behaviour. Significant, though small, positive correlations were observed between identity and health behaviour as predicted. Regression analyses and path analysis were used to present a model of the link between variables. Of particular note were the contrasting ways in which the two dimensions of identity were associated with health behaviour. Participants who positively evaluated their ethnic origins reported engaging in healthier behaviour and adopting more beneficial coping strategies when faced with day-to-day stresses and problems. Participants who reported their ethnic origin as more central to their overall identity were also more likely to adopt beneficial coping strategies. Concomitantly, however, they had fewer than desired opportunities for expressing their ethnic identity which was, in turn, associated with less beneficial coping and health behaviour. In looking for ways to tackle the well-documented health problems of both first and second generation Irish in England, the results suggest that encouragement to feel more positive about their ethnic identity might result in greater usage of behavioural approach coping and, relatedly, to improved health behaviour. 相似文献

The market place has seen significant growth in the demand for ‘ethical’ products and services. Yet, consumers often experience knowledge, evaluation and choice uncertainties in decision‐making processes, particularly in relation to products such as ethical clothing. The authors explore this pertinent form of consumer uncertainty through three qualitative studies of ethical consumers that examine their approaches to clothing consumption. In‐depth interviews and focus groups confirm uncertainty arises; the results also identify the causes and consequences of consumer uncertainty in this context. The causes of uncertainty pertain to issues surrounding complexity, ambiguity, conflict and credibility that give rise to uncertainties that result in delaying purchase decisions, compromising beliefs and negative emotions. This study contributes to literature by offering a holistic understanding of the challenges facing consumers when making ethical choices. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons. 相似文献

Fifty years ago the neurologist MacDonald Critchley observed that parietal cortex damage impaired temporal as well as spatial experience. Whereas the physiological understanding of space has since advanced, the same cannot be said of time. However, in a novel study, recording from single neurons in the macaque, Leon and Shadlen show that a region of the parietal cortex appears to encode time. The area in which these neurons reside also contains spatially selective neurons and overlaps with the area recently reported to contain number neurons. 相似文献

Although reflexivity is critical to the practice of qualitative research, the problem of unconsciousness seems to stand in its way. If aspects of lived experience are unconscious to an engaged participant, then how can one become reflexive? This paradox, and the problems it poses for qualitative research, are discussed. Varying conceptualisations of unconsciousness are presented. Unconsciousness can be understood as revealed through language, as primarily non-verbal, or as ultimately irrelevant to human experience. In addition, the source of unconscious material can be conceptualised as internal and subjective, or as contextual and direcdy observable. From these assumptions follow diverse approaches to qualitative research. If unconsciousness is structured via language, then research must focus on the words through which participants describe their experience. If, however, unconsciousness is distinct from language, then qualitative methods must incorporate non-verbal data. The presumed locus of unconsciousness will also affect one's research methods. Internal explanations require querying the subject, and external explanations entail scrutinising context. Examples of qualitative methods and the diverse approaches from which they proceed are presented It is argued that reflexivity demands scrutiny and articulation of the verbal, non-verbal and contextual components that define a particular research project. The author details his own experiences in this regard, and outlines areas in need of further methodological development. 相似文献

The following studies examined the dose and time dependence, site specificity, and reversibility of chlordiazepoxide (CDP)-induced working memory impairments in adult male Sprague-Dawley rats. The rats were tested in a delayed non-match-to-sample radial-arm maze task in which a 1-h delay was imposed between the first four (predelay) and all subsequent (postdelay) arm choices. Intraperitoneal (ip) injection of 2.5 or 5.0 but not 1.25 mg/kg CDP immediately following the predelay session impaired performance in the task. CDP increased the number of errors and decreased the number of correct choices during the postdelay session. The observed working memory impairments also appeared to be site specific since injection of CDP into the medial septum, but not into the anterior amygdala nuclei, immediately following the predelay session also impaired working memory in a dose-related manner. Furthermore, there was a time window for CDP-induced working memory impairments since intraseptal injection of the drug immediately but not 15 min following the predelay session disrupted memory. This observation suggests that the performance deficits reflect disrupted working memory and not proactive effects on performance or the induction of state-dependent learning. In the final experiment, rats were injected ip with either saline or an amnestic dose of CDP (5.0 mg/kg) following the predelay session and then were immediately infused with 10 nmol flumazenil (RO15-1788), a benzodiazepine receptor antagonist or vehicle, into either the medial septum or anterior nuclei of the amygdala. Intraseptal injection of flumazenil prevented the working memory impairments produced by ip injection of CDP. In contrast, intra-amygdala injection of flumazenil did not attenuate, enhance, or modify the CDP-induced working memory impairment. These observations suggest that CDP disrupts working memory by interacting with benzodiazepine receptors in the medial septum. 相似文献

This study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed men using four different operational definitions of vocational orientation, and (2) the relationships among all possible combinations of same named scales across the four inventories. Concurrent validity was studied by administering the Vocational Preference Inventory, the Self Directed Search, and the Holland Scales (Set I and Set II) to 153 male workers established in occupational environments consistent with Holland's six vocational environments. The results revealed that five scales of the VPI and of the Holland Scales (Set I and Set II) and four scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical framework. The correlation coefficients for same named scales for all possible combinations of the four inventories were all found to be significant. In general, the findings of this study tend to support the concurrent validity of Holland's theory for employed men. 相似文献

This study explored the differences in vocational maturity, academic aptitude, and achievement variables among female sorority students who made congruent, incongruent, and undecided occupational choices. The variables were operationally defined by the Career Maturity Inventory, the American College Test Battery, and a self-report questionnaire. Congruent, incongruent, and undecided current occupational choice groups were defined operationally using the Self-Directed Search. The analysis of variance revealed the main effect of groups to be significant for two variables. The findings suggest that students in the congruent female group tend to be more vocationally mature than students in the incongruent and undecided groups. 相似文献
