This study compared nonverbal numerical processing in 6-year-olds with that in nonhuman animals using a numerical bisection task. In the study, 16 children were trained on a delayed match-to-sample paradigm to match exemplars of two anchor numerosities. Children were then required to indicate whether a sample intermediate to the anchor values was closer to the small anchor value or the large anchor value. For two sets of anchor values with the same ratio, the probability of choosing the larger anchor value increased systematically with sample number, and the psychometric functions superimposed when plotted on a logarithmic scale. The psychometric functions produced by the children also superimposed with the psychometric functions produced by rhesus monkeys in an analogous previous experiment. These examples of superimposition demonstrate that nonverbal number representations, even in children who have acquired the verbal counting system, are modulated by Weber's law.  相似文献

Numerous theoretical models have been proposed to explain motivation in organizational settings. Several authors such as Herzberg, Deci and Ryan distinguish between intrinsic and extrinsic motivation. A new approach to intrinsic motivation (François, 2003) is now developping in France. It consists of considering that “intrinsic motivation” is a social norm. We have tested the normativity of intrinsic motivation in two field studies using the judge's paradigm. The first study was conducted on 52 recruiters, the second was conducted on 25 experts evaluating a project concerning the creation of an organization. Results show that evaluators prefered intrinsically motivated than extrinsically motivated candidates in both studies. Finally evaluators used utilitarians traits to describe intrinsically motivated candidates. This result gives force to a normative interpretation of intrinsic motivation.  相似文献

Recent attempts to medicalize women’s sexual “dysfunction” are critiqued and a “New View” of women’s sexual problems is introduced. The author argues for a female-centered perspective on women’s sexual desires and problems, based on a review of the literature on women’s sexuality and her observations of young women’s sexual experiences from 25 years of teaching Human Sexuality to undergraduate women. The review suggests that a pill or a patch cannot adequately address the sexual problems commonly experienced by US women.  相似文献

This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network whose components correspond to regions of the cerebral cortex and cerebellum, including premotor, motor, auditory, and somatosensory cortical areas. Computer simulations of the model verify its ability to account for compensation to lip and jaw perturbations during speech. Specific anatomical locations of the model's components are estimated, and these estimates are used to simulate fMRI experiments of simple syllable production.  相似文献

We used 1997 International Social Survey Programme data from 14 countries to examine the relationship of job attribute preferences to family responsibilities, employment, and paid work hours. Separate regression analyses for women and men examined whether family responsibilities (marriage, children, spousal employment, and housework responsibility) predicted job attribute preferences. Many family responsibilities were significant predictors of men's and women's extrinsic and intrinsic preferences. Family responsibilities also predicted women's flexibility preferences. We next examined whether job attribute preferences were associated with employment and weekly paid work hours when family responsibilities were controlled. Job attribute preferences showed several significant relationships to women's and men's employment and several significant relationships to women's paid work hours.  相似文献

Perfectionism is linked to a range of psychological disorders. Burnout is an important construct in the working population and has been found to overlap with related constructs such as depression. There has been limited research conducted between perfectionism and burnout. This study aimed to examine the link between perfectionism and burnout and if procrastination and over commitment to work were mediators of the relationship. There were 69 participants recruited who were seeking counselling from a counselling firm, providing employee assistance services. The results indicated that procrastination was not a significant mediator of the relationship between concern over mistakes (CM) perfectionism and burnout. There was a significant mediating relationship found, where overcommitment to work mediated the relationship between CM perfectionism leading to burnout. The implications of the study in terms of interventions for employees suffering burnout, and directions for future research in regards to the relationship between perfectionism and burnout are considered.  相似文献

This paper focuses on recent debates over the nature ofliberalism and its central feature of reason, both inside and outside ofeducational philosophy. Central ideas from Jonathan and Hirst contributeas do those from Rawls, Gadamer, Wittgenstein, Taylor, and Ackermantoward a less traditional contextualized and contingent view.  相似文献

Alzheimer’s disease (AD) and diabetes rarely occur together, a finding that provides a possible clue as to the development of AD. Abnormal glucose metabolism is not limited to diabetes, but also can include impaired glucose tolerance, insulin resistance, and hyperinsulinemia. AD patients have significantly varying insulin levels after drinking sugared sodas and thus may be classified as insulin resistant. After reviewing the literature on impaired glucose tolerance and insulin production in AD, we present several hypotheses as possible explanations for the relationship between insulin resistance and AD. Finally, we suggest future studies, including studies on use of thiazolidinediones (currently used in the treatment of diabetes) in AD.  相似文献

Since knowledge intensive work often requires self-management, one might fear that persons who are dependent on work success for self-esteem will have difficulties in finding a healthful and sustainable balance between internal needs and external demands. Accordingly, we examined to what degree work-related performance-based self-esteem (PBS) was linked to work and health behaviors in 392 knowledge workers (226 women, 166 men). In the women group, multiple binary logistic regression analyses with repeated measurements showed that the PBS score was associated with 10 of the 17 examined work and health behaviors. For men the corresponding figure was 3 of 17. In both men and women, higher PBS scores were positively associated with reports of efforts and strivings for work as well as attending work while ill. In conclusion, statistically significant relationships between PBS and work and health behaviors were more clearly visible among women than men. Whether this gender difference is dependent on the study design, or on true inherent differences between women and men, cannot be concluded with any certainty. However, persons who described themselves as being relatively more dependent on work accomplishments for a high self-esteem, as expressed by the PBS score, seem to display work behaviors that may lessen their restitution time. In addition, they also seem to be more prone to work while sick.  相似文献

设计调查问卷对深圳某基层医院实施病人满意度调查及相关因素的医学伦理分析。结果显示病人满意度不高,门急诊病人的总满意度明显低于住院病人;病人对服务态度、就医环境和诊疗费用等都较不满意。其中医院未能遵循及时、准确、有效、择优和自主原则是主要影响因素。  相似文献
