Anglo-American Postmodernity: A Response to Clayton and Robbins

In Anglo-American Postmodernity I call attention to recent intellectual shifts in epistemology (from foundationalism to holism), philosophy of language (from reference to use), and metaphysics (from reductionism to nonreductionism), and pursue the consequences of these changes for science, theology, and ethics. Wesley Robbins criticizes the book for making overly optimistic claims for the intellectual status of theology; Philip Clayton criticizes it for giving up the quest for general standards of rational progress. Both criticisms miss the mark in not taking on the account of rationality that I have developed from resources in the work of Alasdair MacIntyre.     

THE RELIGION OF A SCIENTIST: EXPLORATIONS INTO REALITY (RELIGIO PHILOSOPHI NATURALIS)

Abstract. Sir Thomas Browne's reflection on the synthesis between his Christian religion and his practice as a medical doctor, made over three centuries ago, leads into reflections on the present relation between religion and science in the personal experience of the writer. An account is given of how the actual practice of scientific investigation led the author to theistic inferences and how the study of DNA provoked questions concerning reductionism and emergence. This evoked the need for a map of knowledge, and an attempt is presented in a figure which also serves to clarify what kind of realistic reference is involved in both scientific and humanistic contexts–especially with respect to personal language. Theological investigations thereby receive at least provisional legitimization and, with this encouragement, the article pursues the questions of the nature of the divine Source ("God") of the world's being and becoming, of God's interaction and communication with the world, especially with human beings in that world. The penultimate section outlines why the writer considers an explicit communication from God to humanity in Jesus of Nazareth is coherent with the foregoing and what this implies for human fulfillment, individually and corporately. The article concludes with a plea for humility before God and nature in our inquiries in the spirit both of Sir Thomas Browne and of the arch "agnostic" T. H. Huxley.     

Visualising mental representations: A primer on noise-based reverse correlation in social psychology

With the introduction of the psychophysical method of reverse correlation, a holy grail of social psychology appears to be within reach – visualising mental representations. Reverse correlation is a data-driven method that yields visual proxies of mental representations, based on judgements of randomly varying stimuli. This review is a primer to an influential reverse correlation approach in which stimuli vary by applying random noise to the pixels of images. Our review suggests that the technique is an invaluable tool in the investigation of social perception (e.g., in the perception of race, gender and personality traits), with ample potential applications. However, it is unclear how these visual proxies are best interpreted. Building on advances in cognitive neuroscience, we suggest that these proxies are visual reflections of the internal representations that determine how social stimuli are perceived. In addition, we provide a tutorial on how to perform reverse correlation experiments using R.

时序知觉影响因素与思考

时序知觉是在几十毫秒到几百毫秒内, 对事件的同时性、非同时性和顺序性的知觉。对时序知觉的影响因素的探索可分为自下而上和自上而下两种研究取向。自下而上的研究探讨刺激的物理特征、被试的生物学特征, 以及实验方法对时序知觉的影响。而自上而下的研究探讨因果信念、情绪、文化对时序知觉的影响。今后的研究还应结合行为实验与神经科学技术, 深入探讨时序知觉的两种加工方式是分离的还是同时进行的, 以及揭示控制时序加工的脑区。     

一种自上而下加工的注意选择新机制:视觉标记

视觉标记是国外新近提出的有关注意选择机制的一种假设。该假设认为,在任务目标预先设定的条件下视觉系统是通过抑制旧刺激所处的位置来实现对新刺激的优先选择。本文主要介绍了视觉标记研究的经典实验范式、视觉标记理论的行为实验依据和脑成像实验依据,还概述了三种质疑视觉标记理论的观点。最后对视觉标记的未来研究做了展望。     

用于处理不努力作答的标准化残差系列方法和混合多层模型法的比较

文章采用模拟研究, 分别在混合多层模型假设满足和违背的情境下, 比较了混合多层模型方法与标准化残差系列方法在识别不努力作答和参数估计方面的表现。结果显示：(1)不存在不努力作答或其严重性低时, 各方法表现接近; (2)不努力作答严重性高时, 固定参数迭代标准化残差法普遍更优, 混合多层模型法仅在假设满足且两种作答反应时差异大的条件下表现较好。建议实际应用中优先选择固定参数迭代标准化残差法。     

Unconscious Familiarity and Local Context Effects on Low-Level Face Processing: A Reconstruction Hypothesis

A common view in face recognition research holds that there is a stored representation specific to each known face. It is also posited that semantic or memory-based information cannot influence low-level face processing. The two experiments reported in this article investigate the nature of this representation and the flow of face information processing. Participants had to search for a particular primed face among other faces. In Experiment 1, the search was done in a context where distractors had either a different degree of fame or the same degree of fame. In Experiment 2, the target face was primed either with semantic information or without any information. Both experiments demonstrated that increasing the display set size lengthened face detection time. However, the lengthening was a function of face fame. The search context also had an effect on the slope of the famous face detection. The results are explained in terms of the idea that face representations are reconstructed and that high- and low-level information are integrated into the processing. The integration process is not a conscious one.     

Does emotion influence visual perception? Depends on how you look at it

ABSTRACT

One of the biggest challenges in the study of emotion–cognition interaction is addressing the question of whether and how emotions influence processes of perception as distinct from other higher-level cognitive processes. Most theories of emotion agree that an emotion episode begins with a sensory experience – such as a visual percept – that elicits a cascade of affective, cognitive, physiological, and/or behavioural responses (the ordering and inclusion of those latter components being forever debated). However, for decades, a subset of philosophers and scientists have suggested that the presumed perception → emotion relationship is in fact bidirectional, with emotion also altering the perceptual process. In the present review we reflect on the history and empirical support (or, some might argue, lack thereof) for the notion that emotion influences visual perception. We examine ways in which researchers have attempted to test the question, and the ways in which this pursuit is so difficult. As is the case with the ongoing debate about the cognitive penetrability of perception, we conclude that nothing is conclusive in the debate about the emotional penetrability of perception. We nonetheless don rose-coloured glasses as we look forward to the future of this research topic.
