As an individual’s understanding of their genetic risk may influence risk management decisions, it is important to understand the ways in which risk is constructed and interpreted. We systematically reviewed the literature, undertaking a narrative synthesis of 59 studies presenting data on the ways in which individuals perceive, construct and interpret their risk, and the subsequent effects. While most studies assessed perceived risk quantitatively, the combined evidence suggests individuals find risk difficult to accurately quantify, with a tendency to overestimate. Rather than being a stand-alone concept, risk is something lived and experienced and the process of constructing risk is complex and influenced by many factors. While evidence of the effects of perceived risk is limited and inconsistent, there is some evidence to suggest high risk estimations may adversely affect health and lead to inappropriate uptake of medical surveillance and preventative measures by some individuals. A more focused approach to research is needed with greater exploration of the ways in which risk is constructed, along with the development of stronger theoretical models, to facilitate effective and patient-centered counseling strategies.  相似文献

Hippocampal-dependent synaptic plasticity and memory are modulated by apamin-sensitive small conductance Ca2+-activated K+ (SK) channels. Transgenic mice overexpressing SK2 channels (SK2+/T mice) exhibit marked deficits in hippocampal memory and synaptic plasticity, as previously reported. Here, we examined whether SK2 overexpression affects the encoding or retention of contextual memory. Compared with wild-type littermates, SK2+/T mice exhibited significantly less context-dependent freezing 10 min and 24 h after conditioning. Interestingly, this contextual memory impairment was eliminated if SK2+/T mice were permitted longer pre-exposure to the conditioning chamber. These data support converging evidence that SK2 channels restrict the encoding of hippocampal memory.  相似文献

Humans are often seen as unusual in displaying altruistic behaviour towards non‐relatives. Here we outline and test a hypothesis that human altruistic traits evolved as a result of sexual selection. We develop a psychometric scale to measure mate preference towards altruistic traits (the MPAT scale). We then seek evidence of whether mate choice on the basis of altruistic traits is present and find it in one study (N=170 couples). We also predict that a stronger female MPAT, as measured by responses to the MPAT scale, will be expressed – a result found in all three studies (Ns=380, 340, and 398). Both sets of results are consistent with the hypothesized link between human altruism towards non‐relatives and sexual selection.  相似文献

The purpose of this study was to examine differences in the perceptions of initial careers guidance interviews as expressed by pupils and careers advisers. A sample of 51 careers guidance interviews were studied, which were carried out by 16 qualified careers advisers operating under normal working conditions. The school pupils were from the lower streams of 16 different secondary level schools, half were male, and the majority were either unsure of leaving or were planning to leave school at the earliest opportunity. The study adopted a quantitative repeated measures design where both interview participants completed pre-interview expectation questionnaires, post-interview recall questionnaires and scales measuring interview evaluations. The results suggested a range of differences between careers advisers' and pupils' expectations, recall and evaluations of careers guidance interviews. However, both participants' overall satisfaction with the careers interview was significantly related to the interpersonal aspects of the process, while the provision of careers advice contributed to overall satisfaction expressed by careers advisers only. The findings are discussed in relation to evaluation of provision and the preparation of clients for participation in careers guidance interviews.  相似文献

People who possess poor social skills have been hypothesized to experience negative events and consequently become vulnerable to psychosocial problems. This is characterized as the social skills deficit stress generation hypothesis. Two studies were conducted to examine this hypothesis. In study 1, 677 university students completed measures of social skills and negative life events that had occurred over the past three months. In study 2, 142 students participated in a 9 month, 3 wave longitudinal study that assessed social skills at times 1 and 3 and negative life events at times 2 and 3. Results of the investigations indicate generally negative associations between social skills and negative life events, but these associations were stronger concurrently than prospectively. Although social skills were predicted to be associated with negative life events that are social in nature, in most cases they were equally predictive of nonsocial negative life events. The associations between the social skills and life events were consistently small in magnitude. This research was supported in part by University of Kansas General Research allocation 3011-20-0038 and 3825-20-0038. The author expresses gratitude to Jeanne Flora, Clark Henry, and Michelle Menees for their assistance with coding.  相似文献

The authors present the results of a content analysis of articles that were published in the Journal of Multicultural Counseling and Development (JMCD) during the last 15 years. The analysis identified the leading contributors (i.e., authors, institutions) to JMCD, evaluated the content of the articles, examined the type of articles, and highlighted the particular cultural groups that were studied most frequently. Los autores presentan los resultados de un análisis de el contenido de la Revista de Consejeria y Desarrollo Multicultural (JMCD), durante los ultimos 15 años. El análisis identificó los contribuyentes más destacados (en otras palabras, los autores, las instituciones) a JMCD; examinó el tipo del articulos y subrayó los grupos culturales que se estudiaron más frecuentemente.  相似文献

Structure of the Indonesian Emotion Lexicon   总被引:1,自引:0,他引:1  
Based on a prototype approach to emotion concepts, two studies were conducted: (1) to identify the mental state words that Indonesian speakers are most certain name emotions ( perasaan hati ) and (2) to map the hierarchical and family-resemblance structure of the top 124 emotion concepts. As in an earlier study of emotion terms in American English (Shaver, Schwartz, Kirson, & O'Connor, 1987), cluster analysis of sorting data collected in Indonesia revealed five basic-level emotion categories: cinta (love), senang (happiness), marah (anger), kawatir/takut (anxiety/fear), and sedih (sadness). Also in line with the American results, the five basic-level categories formed two large categories at the superordinate level: positive emotions and negative emotions. Each of the five basic-level categories contained several subordinate-level categories, totaling 31 in all. The results suggest that the emotion lexicons, and corresponding conceptualizations of the emotion domain, in Indonesia and the U.S.A. are similar at the superordinate and basic levels but somewhat variable at the subordinate level. This outcome – like other kinds of psychological research on emotions and emotion concepts – suggests that the gross structure of representations of the emotion domain are similar worldwide, perhaps for biological reasons, but that different cultures make different fine-grained distinctions and emphasize different subordinate-level emotion concepts.  相似文献

Proponents of 'the poetic hypothesis>> in Kant interpretation assume that the third Critique provides the necessary and sufficient conditions for understanding the nature of all theological discourse. This article opens with the assumption – taken from one of Kant's last works – that philosophy and theology must always remain in conflict. Then, by way of an abductive comparison of Gordon Kaufman and Adina Davidovich, I demonstrate that the poetic hypothesis leads to religious compromises that contradict this assumption. To conclude, I argue for an understanding of the motif of holism that is better able to uphold Kant's notion of conflict.  相似文献

This study investigated the potential for recreational gamblers to respond as if certain types of losing slot machine outcomes were actually closer to a win than others (termed the near‐miss effect). Exposure to conditional discrimination training and testing disrupted this effect for 10 of the 16 participants. These 10 participants demonstrated high percentages of conditional discrimination testing performance, and the remaining 6 participants failed the discrimination tests. The implications for a verbally based behavioral explanation of gambling are presented.  相似文献
