Many letters of the alphabet are consistently mapped to specific colours by English-speaking adults, both in the general population and in individuals with grapheme-colour synaesthesia who perceive letters in colour. Such associations may be naturally biased by intrinsic sensory cortical organisation, or may be based in literacy (eg 'A' is for 'apple', apples are red; therefore A is red). To distinguish these two hypotheses, we tested pre-literate children in three experiments and compared their results to those of literate children (aged 7-9 years) and adults. The results indicate that some colour letter mappings (O white, X black) are naturally biased by the shape of the letter, whereas others (A red, G green) may be based in literacy. They suggest that sensory cortical organisation initially binds colour to some shapes, and that learning to read can induce additional associations, likely through the influence of higher-order networks as letters take on meaning. 相似文献

A series of papers in Philosophy, Ethics and Humanities in Medicine (PEHM) have recently disputed whether non-heart beating organ donors are alive and whether non-heart beating organ donation (NHBD) contravenes the dead donor rule. Several authors who argue that NHBD involves harvesting organs from live patients appeal to "strong irreversibility" (death beyond the reach of resuscitative efforts to restore life) as a necessary criterion that patients must meet before physicians can declare them to be dead. Sam Shemie, who defends our current practice of NHBD, holds that in fact physicians consider patients to be dead or not according to physician intention to resuscitate or not. We suggest that criteria for a concept are not necessarily truth conditions for assertions involving the concept. Hence, non-heart beating donors may be declared dead without meeting the criterion of strong irreversibility even though strong irreversibility is implied by the concept of death. Our perception that a concept applies in a given case is determined not by the concept itself but by our necessary skill and judgment when using it. In the case of deciding that a patient is dead, such judgment is learned by physicians as they learn the practice of medicine and may vary according to circumstances. Current practice of NHBD can therefore be defended without abandoning death as an empirical concept, as Shemie appears to do. We conclude that the dead donor rule continues to be viable and ought to be retained so as to guarantee what the public most cares about as regards organ donation: that physicians can be trusted to make determinations of eligibility for organ donation in the interests of patients and not for other purposes such as increasing the availability of organs. 相似文献

In this article we explore the content and dynamics of patients' verbalizations within a "living with medications" group. Patients' perceptions of their psychotropic medications are interpreted and classified within the framework of object relations theory. One's perception of the role of medication in one's life can serve as a gateway to one's inner world and the way that he or she perceives authority figures, peers, and oneself. We suggest that working through patients' relationships with their medications can help them to achieve better integration of internal object relations. Discussing patients' views about medications should therefore be seen as an important part of psychotherapy with many individuals. Such a discussion may enhance and improve efficacy of both psychotherapy and pharmacotherapy. It is of particular importance in group therapy, within milieu environments and with individuals reluctant to explicitly discuss interpersonal matters. Vignettes from the group sessions illustrate the way in which discussing medication advances group process. 相似文献

The relation between work-family conflict (WFC) and job satisfaction was examined using a six-dimensional measure of WFC and both global and summed facet (i.e., composite) measures of job satisfaction. Data were gathered from 160 hospital employees who were married, living with a partner, or had at least one child or dependent living at home and worked a minimum of 20 h/week. The results indicated that WFC related significantly to both types of job satisfaction, but the relation was significantly stronger to composite job satisfaction than to global job satisfaction. When considering all three forms of conflict simultaneously (time-based, strain-based, and behavior-based), regression results revealed that behavior-based was the only form of conflict significantly related to job satisfaction. The results underscore the importance of considering both the form and direction of WFC and suggest several practical implications for organizations. 相似文献

We applied quantitative genetics techniques to a sample of 851 pairs of monozygotic and 855 pairs of dizygotic female twins to examine the influence of genetic factors on the variation across people in opportunity recognition. We also examined the extent to which the same genetic factors contribute to both opportunity recognition and the tendency to be an entrepreneur. We found substantial heritability for opportunity recognition (0.45), with no influence of the shared environment. Moreover, we found that 53% of the phenotypic correlation between opportunity recognition and the tendency to be an entrepreneur had a common genetic aetiology. 相似文献

The purpose of this study was to test the relationship between IQ and physical aggression in a nonclinical-nonforensic male sample in a laboratory setting. Thirty males completed an abbreviated version of the Wechsler Adult Intelligence Scale—Revised. Aggression was measured using a modified version of the Taylor reaction-time (RT) aggression paradigm in which subjects competed on a RT task and both received and delivered shocks to a fictitious opponent in provoking and nonprovoking conditions. Provocation conditions (High and Low) were defined by the intensity of shocks the subjects received. Results demonstrated strong inverse correlations between IQ and aggressive behavior under both High and Low Provocation conditions. 相似文献

Based on findings from the domain of organizational frustration, the conceptual similarity between stress and frustration, and the functional similarity between frustrated events and work stressors, the relationships of behaviours (aggression, withdrawal, theft and substance use) with work stressors and affective reactions were investigated. Relations between reported stressors and behaviours were strongest for the more directly aggressive actions (sabotage, interpersonal aggression, and hostility and complaints), and for intention to quit. Relations with theft and absence were modest. None of the stressors correlated with reported substance use at work. Among the relations between affective reactions and the reported behaviours, anger and job satisfaction correlated with all behaviours except substance use at work. Hierarchical regression results further showed that the observed associations between stressors and behaviours were not attributed to affective variables for most cases. 相似文献

Spatial versus tree representations of proximity data 总被引:2,自引:0,他引:2
In this paper we investigated two of the most common representations of proximities, two-dimensional euclidean planes and additive trees. Our purpose was to develop guidelines for comparing these representations, and to discover properties that could help diagnose which representation is more appropriate for a given set of data. In a simulation study, artificial data generated either by a plane or by a tree were scaled using procedures for fitting either a plane (KYST) or a tree (ADDTREE). As expected, the appropriate model fit the data better than the inappropriate model for all noise levels. Furthermore, the two models were roughly comparable: for all noise levels, KYST accounted for plane data about as well as ADDTREE accounted for tree data. Two properties of the data proved useful in distinguishing between the models: the skewness of the distribution of distances, and the proportion of elongated triangles, which measures departures from the ultrametric inequality, Applications of KYST and ADDTREE to some twenty sets of real data, collected by other investigators, showed that most of these data could be classified clearly as favoring either a tree or a two-dimensional representation.A portable PASCAL program implementing the Sattath and Tversky [1977] ADDTREE algorithm is available from J. Corter, Department of Psychology, Stanford University, Stanford, California 94305. 相似文献

Subjects first rated similarity of verbal and of pictorial stimuli. The same pairs of stimuli were presented again, without one common component and one distinctive component. Subjects were asked to recall the missing components and identify them as common or distinctive. The results show that components encoded as common are recalled relatively better than components encoded as distinctive, and the difference in recall is significantly greater in verbal than in pictorial stimuli. 相似文献
