Eye movements of 30 4-month-olds were tracked as infants viewed animals and vehicles in “natural” scenes and, for comparison, in homogeneous “experimental” scenes. Infants showed equivalent looking time preferences for natural and experimental scenes overall, but fixated natural scenes and objects in natural scenes more than experimental scenes and objects in experimental scenes and shifted fixations between objects and contexts more in natural than in experimental scenes. The findings show how infants treat objects and contexts in natural scenes and suggest that they treat more commonly used experimental scenes differently.  相似文献

Olfactory attention may be important in generating odor-induced tastes - an arguably universal form of synesthesia - by ensuring that the taste concurrent is captured by the nose and olfaction, not by the mouth and gustation (oral-capture). To examine the role of olfactory attention in generating odor-induced tastes and oral capture we tested a small sample (n = 4) of participants with likely impairments in olfactory attention - individuals with mediodorsal thalamic nucleus (MDNT) lesions. These participants were compared to two sets of controls on tests of olfactory attention, oral capture, odor and flavor perception, and control tasks. MDNT participants demonstrated impaired olfactory attention and enhanced oral capture. Greater oral capture was associated with greater olfactory attentional impairment. These findings imply that olfactory attention may be important in attributing odor-induced tastes to the olfactory modality. However, unlike for visual binding and for the neurodevelopmental synesthesias, where attention may be necessary to demonstrate both phenomena, olfactory attention deficits did not impair flavor binding or the experience of odor-induced tastes.  相似文献

Prenatal genetic counselors are health care professionals who counsel women making reproductive decisions which include decisions such as terminating pregnancies due to fetal anomalies. Little is known about the experiences and practices of prenatal genetic counselors working with women who have the option of termination after 24 weeks gestation. In this national survey of 168 genetic counselors who have practiced prenatal genetic counseling, we asked about their general practice patterns, including indications for which termination is offered and types of abortion care services that are coordinated by genetic counselors. We report respondents’ self-assessments of level of understanding of federal abortion law and abortion procedures. Seventy-six percent of respondents have offered and counseled on termination after 24 weeks and 93% of respondents believe it is the responsibility of the counselor to discuss this option with patients. However, one-third report that they have some or no understanding of the procedures and three-quarters report that they have some or no understanding of federal abortion law. The results of this study provide insight into knowledge and experiences of genetic counselors working with these patients, allowing for improved genetic counselor training and continuing education to provide better guidance and develop more effective means of assisting patients.  相似文献

Within family stress theories, the way in which families communicate about their hardships and issues is crucial for the family’s stress management and functioning. In the current study, we sought to validate the Portuguese version of the Family Problem Solving Communication (FPSC) Index and examine its psychometric properties. Developed within the context of the resiliency model of family stress, adjustment and adaptation, the FPSC is a ten-item self-report measure that assesses the family communication patterns that are likely to play a role in the family’s coping with hardships and difficulties. The participants were 332 individuals between 18 and 76 years who completed the FPSC and self-report measures of family hardiness and family functioning. A confirmatory factor analysis supported the original FPSC bifactorial structure, indicating the presence of two dimensions, Affirmative Communication and Incendiary Communication. Correlations between the scale’s total score and its dimensions with the measures of family hardiness and family functioning attested to its convergent validity. Furthermore, the index demonstrated respectable to very good internal consistency and temporal stability. In conclusion, the Portuguese version of the FPSC is a valid and reliable instrument that can support the development of future empirical studies focused on family problem solving communication, especially with regard to family adaptation in different contexts of adversity.  相似文献

This study investigated a new direction for improving the decision making of populations at risk in the context of uncertain environmental events, such as volcanic hazards. According to the risk as feelings theory and dual process models, situations with certain outcomes do not necessarily require the use of affect heuristics (e.g., experienced feelings, anticipated emotions) as valid information in the decision‐making process. In the case of difficult decisions with moral dilemmas, certainty could even improve decisions. Thus, using an ecological design with various scenarios depicting upcoming volcanic hazards, we examined whether reducing the uncertainty of lethal threat by conveying certainty in an information campaign could influence decision making and promote a better quality of choice (correct application of the recommendations from the competent authorities). We focused specifically on two populations composed of local people living in the vicinity of an active volcano (Tungurahua volcano, Ecuador) and local scientists. We also examined whether a difficult decision involving a moral dilemma (e.g., leaving people behind so as not to jeopardize one's own life) potentiated this effect, compared to a less difficult situation without a dilemma. We demonstrated that, for local people facing a moral dilemma (difficult decision), the reduction of uncertainty of lethal threat involved a better application of the actual recommendations. These outcomes provided perspectives on improving the applications of the recommendations among local populations at risk in the context of a real risk exposure.  相似文献

This paper examines the impact of context on careers. It is based on a study of senior managers in an English local authority. It offers two important contributions: first, an empirical contribution examining how context matters to individuals in their career-making in the setting of the UK public sector. Our findings point to three aspects or faces of context: proximal events, ideology and enduring structural features. The first, context as ideology, attends to meaning-making that is collective in nature, and that incorporates concepts of power, domination, subordination and resistance. Our second refers to the enduring structural features. These are on-going trends and developments, predictable and traceable over the medium to long-term which offer rules and resources, thus structuring opportunity and constraint. Finally, the third face, context as proximal events, refers to (often unexpected) contingencies that arise at particular moments. Although bounded both spatially and temporally, they can significantly impact on career decision making. The second contribution of the paper builds upon this empirical base to develop theoretical and conceptual understanding of the link between career and context, illustrating the interconnectedness of the various faces of context and the dynamic ways in which these influence career-making over time.  相似文献

Vision begins with the processing of unbound visual features, which must eventually be bound together into object representations. Such feature binding is required for coherent visual perception, and accordingly has received a considerable amount of study in several domains. Neurophysiological work, often in monkeys, has revealed the details of how and where feature binding occurs in the brain, but methodological limitations have not allowed this research to elucidate just how feature binding operates spontaneously in real-world situations. In contrast, behavioral work with human infants has demonstrated how we use simpler unbound features to individuate and identify objects over time and occlusion in many types of events, but this work has not typically been able to isolate the role of feature binding in such processing. Here we provide a method for assessing the spontaneity and fidelity of feature binding in non-human primates, as this process is utilized in real-world situations, including simple foraging behaviors. Using both looking-time and manual-search measures in a natural environment, we show that free-ranging rhesus macaques (Macaca mulatta) spontaneously bind features in order to individuate objects across time and occlusion in dynamic events. This pattern of results demonstrates that feature binding is used in subtle ways to guide ecologically relevant behavior in a non-human animal, spontaneously and reliably, in its natural environment.  相似文献
