Previous research has demonstrated that, presumably as a way to protect one’s current romantic relationship, individuals involved in a heterosexual romantic relationship tend to give lower attractiveness ratings to attractive opposite-sex others as compared to uninvolved individuals (i.e., the derogation effect). The present study importantly extends this research by examining whether romantic relationship status actually biases memory for the facial appearance of attractive (vs. unattractive) mates. To address this issue, we used a reverse-correlation technique (Mangini & Biederman, 2004), originally developed to get a visual approximation of an individual’s internal representation of a target category or person. In line with the derogation effect, results demonstrated that romantically involved (vs. uninvolved) individuals indeed held a less attractive memory of a previously encountered attractive mate’s face. Interestingly, they also held a more attractive memory of an unattractive mate’s face as compared to uninvolved individuals. This latter finding may suggest that romantically involved (as compared to uninvolved) individuals differentiate opposite-sex others along the attractiveness dimension less.  相似文献

文章主要针对中国古代语言和论证的一些重要方面进行探讨,特别地,我们重点考察了儒家和墨家的观点。我们主张使用轻型的逻辑模型方法(不引进全部的现代逻辑演算)对一些重要的概念提供解释。我们所关注的问题主要有:情景辨别和做出反应、根据合适的反应来正名、以及通过"法"和"因"两个方面讨论类的外延。我们尝试使用博弈模型来表示古代论证的实际情形,重点讨论关于对象和类之间关系的争辩。在文章的最后,我们讨论了使用博弈建模方法对于理解古代中国推理实践潜在的可能性。  相似文献

This article illustrates a dissociation between the perceived attributes of an object and the ability of those attributes to guide the deployment of attention in visual search. Orientation is an attribute that guides search. Thus, a vertical line will “pop out” amid horizontal distractors. Amodal completion can create perceptually convincing oriented stimuli when two elements appear to form a complete object partially hidden behind an occluder. Previous work (e.g., Rensink &; Enns, Vision Research, 38, 2489–2505, 1998) has shown a preattentive role for amodal completion in search tasks. Here, we show that orientation based on perceptually compelling amodal completion may fail to guide attention. The broader conclusion is that introspection is a poor guide to the capabilities of our internal search engine.  相似文献

In historical claims for nativism, mathematics is a paradigmatic example of innate knowledge. Claims by contemporary developmental psychologists of elementary mathematical skills in human infants are a legacy of this. However, the connection between these skills and more formal mathematical concepts and methods remains unclear. This paper assesses the current debates surrounding nativism and mathematical knowledge by teasing them apart into two distinct claims. First, in what way does the experimental evidence from infants, nonhuman animals and neuropsychology support the nativist hypothesis? Second, granting that infants have some elementary mathematical skills, does this mean that such skills play an important role in the development of mathematical knowledge?  相似文献

Dysfunctional self-schemas are assumed to play an important role in suicidal ideation. According to recent information-processing models, it is important to differentiate between ‘explicit’ beliefs and automatic associations. Explicit beliefs stem from the weighting of propositions and their corresponding ‘truth’ values, while automatic associations reflect more simple associations in memory. Both types of associations are assumed to have different functional properties and both may be involved in suicidal ideation. Thus far, studies into self-schemas and suicidal ideation focused on the more explicit, consciously accessible traces of self-schemas and predominantly relied on self-report questionnaires or interviews. To complement these ‘explicit’ findings and more directly tap into self-schemas, this study investigated automatic self-associations in a large scale community sample that was part of the Netherlands Study of Depression and Anxiety (NESDA). The results showed that automatic self-associations of depression and anxiety were indeed significantly related to suicidal ideation and past suicide attempt. Moreover, the interactions between automatic self-depressive (anxious) associations and explicit self-depressive (anxious) beliefs explained additional variance over and above explicit self-beliefs. Together these results provide an initial insight into one explanation of why suicidal patients might report difficulties in preventing and managing suicidal thoughts.  相似文献

Taking Löb's Axiom in modal provability logic as a running thread, we discuss some general methods for extending modal frame correspondences, mainly by adding fixed-point operators to modal languages as well as their correspondence languages. Our suggestions are backed up by some new results – while we also refer to relevant work by earlier authors. But our main aim is advertizing the perspective, showing how modal languages with fixed-point operators are a natural medium to work with.  相似文献

The present study concerns a 3-year follow-up of a universal prevention trial targeting anxiety and depressive symptoms in school children. In addition to evaluating the long-term effect of the prevention program, we also examined attrition and its effect on the outcome. High rates of attrition have commonly been observed in studies in the field. However, the role of attrition is not sufficiently understood regarding internal and external validity biases. The current study comprised 695 children (aged 8–11 at baseline) from 17 schools in Sweden. Schools were cluster-randomized to either the intervention or control condition. Children completed measures of anxiety and depressive symptoms and parents completed measures of their child’s anxiety and general mental health. We found no evidence of long-term effects of the prevention program, except for a small effect regarding parent reports of child anxiety. However, that effect was not found to be of clinical significance. Regarding attrition, children with missing data at the 3-year follow-up displayed higher levels of psychiatric symptoms at baseline and increasing symptoms across time. Furthermore, children in the control condition with missing follow-up data were found to be significantly deteriorated across time compared to the corresponding children in the intervention condition regarding depressive symptoms and total difficulties. In other words, attrition served as a moderator of the effect, which suggests that the overall result was biased toward a null-result. Our study highlights that large and nonrandom attrition severely limits the validity of the results. Further, given the common problem of retaining participants in long-term evaluations of school-based prevention trials, previous studies may suffer from the same limitations as the current study.  相似文献

Despite recognition that immigrant women face significant health challenges, addressing the healthcare needs of immigrants is a source of debate in the United States. Lack of adequate healthcare for immigrants is recognized as a social justice issue, and other countries have incorporated immigrants into their healthcare services. Oslo, the fastest growing capital in Europe, is rapidly shifting to a heterogeneous society prompting organizational action and change. The New Families Program serves first-time mothers and their infants in an Oslo district serving 53% minorities from 142 countries. Anchored in salutogenic theory, the program aims to support the parent–child relationship, children's development and social adaptation, and to prevent stress-related outcomes. Formative research has informed the successful program development and implementation within the existing maternal and child healthcare service. Implications for addressing maternal and child health needs of an immigrant population are presented.  相似文献
