具身认知:身体主题在心身关系研究中的回归

上世纪80年代以来,随着经典认知研究的步履维艰,认知研究逐渐显示出具身化的特点。具身认知是第二代认知科学的代表,它强调身体在认知形成中的重要性,认为身体对认知有限制、分配和调节作用,并具有与经典认知不同的运动观。近年来研究者们以实验手段力求为具身认知的存在提供证据,着力考察认知与身体感知运动状态的相互影响。具身认知理论在认知构建、生态效度等方面具有自己的优势,但目前具身认知还是一个新兴的研究领域,有待进一步的深入探讨。     

Varieties of cognitive penetration in visual perception

Is our perceptual experience a veridical representation of the world or is it a product of our beliefs and past experiences? Cognitive penetration describes the influence of higher level cognitive factors on perceptual experience and has been a debated topic in philosophy of mind and cognitive science. Here, we focus on visual perception, particularly early vision, and how it is affected by contextual expectations and memorized cognitive contents. We argue for cognitive penetration based on recent empirical evidence demonstrating contextual and top-down influences on early visual processes. On the basis of a perceptual model, we propose different types of cognitive penetration depending on the processing level on which the penetration happens and depending on where the penetrating influence comes from. Our proposal has two consequences: (1) the traditional controversy on whether cognitive penetration occurs or not is ill posed, and (2) a clear-cut perception–cognition boundary cannot be maintained.     

The meaning of the h-index

The h-index originates from the assumption that the number of citations received by a scientist is a better indicator of the relevance of his or her work than the number of papers he or she publishes or the journals where they are published. It takes into account the number of papers published and the citations to those papers in a balanced way, and thus is useful to make comparisons between scientists. The present paper addresses the most frequent questions about the h-index. Specifically, it explains its origin, its advantages compared to other indices, the factors that can influence it (e.g. age, field of knowledge, topic of research and language of publication), its variants, and the injustices it may lead to. In short, this paper provides a clear exposition of the hoped-for role of the h-index in the evaluation of scientists: that it serves as a useful complement to other indicators that are more subjective, and that it contributes to the progress of science by aiding decision-making on allocation of research resources in a more effective way, and on rewarding researchers who contribute to scientific progress in a more fair way.     

Comparing neurocognitive impairment in schizophrenia and bipolar I disorder using the Screen for Cognitive Impairment in Psychiatry Scale

The purpose of this study was to compare the psychometric properties of the Screen for Cognitive Impairment in Psychiatry (SCIP) when applied to patients diagnosed with schizophrenia (n = 126) or bipolar I disorder (n = 76), and also to compare the cognitive impairment in both samples of patients and a control group (n = 83) using the SCIP and a complete neuropsychological battery. The SCIP is a scale intended to quickly and easily assess cognitive impairment in patients with severe psychiatric disorders. The results showed firstly that, in terms of internal consistency, temporal stability, dimensional structure, and criterion-referenced validity, the SCIP provides reliable and valid scores at an equivalent level in both schizophrenia and bipolar I disorder samples. Secondly, it showed that differential cognitive impairment between the two patient groups occurs only in verbal memory, although the effect size of the difference is small. Finally, compared with the control group, cognitive impairment was present at all levels in both groups of patients using both the SCIP and the neuropsychological battery, which indicates that the SCIP is a good screening tool for cognitive deficits in schizophrenia and bipolar and useful in clinical practice for healthcare professionals.     

Validation of an interpretation bias assessment for body dissatisfaction

Currently, research on interpretation bias and body dissatisfaction is limited. The few experimental paradigms that have been used to explore this phenomenon utilized a method that may not accurately capture the nature of interpretation bias as explained by cognitive theory. The present study investigated the reliability and validity of a novel computerized assessment of interpretation bias (WSAP) for body dissatisfaction, which may more accurately reflect the cognitive processing involved in such bias by implementing the Word Sentence Association Paradigm (WSAP), a previously established method of measuring interpretation bias in other clinical populations. Undergraduate females (n = 214) completed the WSAP and other measures. Results indicate initial support for the WSAP as a valid, reliable measure of interpretation bias for body dissatisfaction. Although preliminary, this study contributes to the minimal research in this area and serves as the first psychometric investigation of the WSAP to measure such interpretation bias for body dissatisfaction.     

Specificity of parental bonding and rumination in depressive and anxious emotional distress

We examined how different dimensions of rumination may mediate the impact of parental bonding (lack of care and overprotectiveness) on negative emotional symptomatology (anxiety and depression). Survey data from participants were analyzed using structural equation modeling. Results indicated that brooding rumination fully mediated the relationship between maternal care and depressive and anxious symptomatology. These findings suggest that to the extent that maternal caregivers are low in warmth and support, offspring are more likely to develop a brooding style of ruminative thinking associated with heightened emotional distress. This research supports the growing body of evidence suggesting that cognitive variables form a pathway between troublesome parent/child interactions and psychopathology.     

ANDREW DICKSON WHITE AND THE HISTORY OF A RELIGIOUS FUTURE

Andrew Dickson White played a pivotal role in constructing the image of a necessary, and even violent, confrontation between religion and science that persists to this day. Though scholars have long acknowledged that his position is more complex, given that White claimed to be saving religion from theology, there has been no attempt to explore what this means in light of his overwhelming attack on existing religions. This essay draws attention to how White's role as a historian was decisive in allowing him to posit a future for religion purified of dogma by science. It argues, furthermore, that this effort is better understood as religious innovation, rather than a plea for strictly secular science. In so doing it hopes to lay the foundation for a more fruitful historical treatment of White, and a range of other figures whose devotion to science has otherwise been difficult to grasp.     

THE MODERN STUDY OF MYTH AND ITS RELATION TO SCIENCE

The history of the modern study of myth can be divided into two main categories: that which sees myth as the primitive counterpart to natural science, itself considered overwhelmingly modern, and that which sees myth as almost anything but the primitive counterpart to natural science. The first category constitutes the nineteenth‐century approach to myth. The second category constitutes the twentieth‐century approach. Tylor and Frazer epitomize the nineteenth‐century view. Malinowski, Eliade, Bultmann, Jonas, Camus, Freud, and Jung epitomize the twentieth‐century approach. The question for the twenty‐first century is whether myth can be brought back to the physical world, but in a way compatible with science. The case of the myth of Gaia will be considered as a possible way of doing so.     

GLOCALIZATION: RELIGION AND SCIENCE AROUND THE WORLD

This essay explains the rationale behind a series of reviews on interactions between knowledge and values, science and religion, in different countries or regions around the world. The series will run in Zygon for the whole of 2015 and beyond. In the literature, it may seem that discussions in the United States and to a lesser extent the United Kingdom are typical of the issues, but they need not be. David Livingstone showed that the reception of evolution differed, even among Calvinists in different countries. Thus, rather than an export model, we should take time to learn from scholars rooted in different contexts how in their situation issues on knowledge and values arise and are dealt with. In this interplay of global processes and local contexts, indicated with the term glocalization, we should be alert to the migration of concepts and the transformations that ideas undergo.
