A Domain-General Theory of the Development of Perceptual Discrimination

ABSTRACT— In this article, we posit a domain-general principle that may account for the improvement that is observed in several aspects of perceptual development over the first years of life. Development during this time frame is characterized by a process of perceptual narrowing, whereby the discrimination of perceptual information is broadly tuned at first and then declines to more selective levels with experience. This process appears to cut across both the visual and auditory modalities and may reflect the development of a common neural architecture.     

知觉适应对种族融合面孔的种族分类和知觉辨别的影响

面孔加工的种族效应(the other-race effects)指人们对面孔做个体辨别任务时辨别本族面孔的绩效优于辨别他族面孔的绩效, 而做种族分类任务时分类他族面孔的绩效优于分类本族面孔的绩效。本研究通过知觉适应操纵被试对种族两歧(高加索和亚洲)融合面孔的种族知觉, 进而比较被试在两种条件下对同一张融合面孔进行种族分类和知觉辨别的绩效的差异。结果发现, 知觉适应能使被试产生将两歧融合面孔知觉为与原始面孔所属种族相反种族的知觉偏向, 并且, 伴随着这种知觉偏向, 两歧融合面孔的加工出现了他族分类优势和本族辨别优势, 提示社会认知因素对面孔加工的种族效应有重要作用。     

Perceptual consciousness plays no epistemic role

It is often assumed that perceptual experience provides evidence about the external world. But much perception can occur unconsciously, as in cases of masked priming or blindsight. Does unconscious perception provide evidence as well? Many theorists maintain that it cannot, holding that perceptual experience provides evidence in virtue of its conscious character. Against such views, I challenge here both the necessity and, perhaps more controversially, the sufficiency of consciousness for perception to provide evidence about the external world. In addition to motivating and defending the idea that unconscious perception can and does often provide evidence, I observe that whether or not perceptual phenomenology is relevant to the evidentiary status of perception depends on the nature of consciousness. And I argue that a well‐supported theory of consciousness—higher‐order thought theory—invites a striking conclusion: that perceptual phenomenology is not on its own sufficient to provide for evidence of the external world.     

Perceptual Integration of Timing and Intensity Variations in the Perception of Musical Accents

The author investigated the detection of timing and intensity variations in tone sequences within the framework of perceptual independence or integration. The participants listened to sequences of tones that contained variations in timing, intensity, or both. Each participant tried to detect variations in the dimension that was declared relevant, which was either timing or intensity. The irrelevant dimension was held constant, or varied in a manner uncorrelated with the relevant dimension, or varied in a correlated manner. When the variations in the 2 dimensions were correlated, the correlation could be either positive (i.e., timing and intensity created accents in the same sequences) or negative (i.e., timing and intensity created accents in different sequences). Uncorrelated variation in the irrelevant dimension interfered with the detection of variations in the relevant dimension. In the case of a positive correlation between the 2 dimensions, the detection of variations was better than it was with the absence of variation in the irrelevant dimension only for participants who attended to timing. In the case of a negative correlation, the effect was the opposite. The results showed that timing and intensity accents were not processed by completely independent channels. Rather, information from the 2 dimensions combined at a late stage of processing.     

Perceptual learning and recognition confusion reveal the underlying relationships among the six basic emotions

The six basic emotions (disgust, anger, fear, happiness, sadness, and surprise) have long been considered discrete categories that serve as the primary units of the emotion system. Yet recent evidence indicated underlying connections among them. Here we tested the underlying relationships among the six basic emotions using a perceptual learning procedure. This technique has the potential of causally changing participants’ emotion detection ability. We found that training on detecting a facial expression improved the performance not only on the trained expression but also on other expressions. Such a transfer effect was consistently demonstrated between disgust and anger detection as well as between fear and surprise detection in two experiments (Experiment 1A, n?=?70; Experiment 1B, n?=?42). Notably, training on any of the six emotions could improve happiness detection, while sadness detection could only be improved by training on sadness itself, suggesting the uniqueness of happiness and sadness. In an emotion recognition test using a large sample of Chinese participants (n?=?1748), the confusion between disgust and anger as well as between fear and surprise was further confirmed. Taken together, our study demonstrates that the “basic” emotions share some common psychological components, which might be the more basic units of the emotion system.

网络词语与非网络词语的知觉差异:时间知觉、空间距离知觉与知觉范围

根据具身认知理论,人们的认知会受到身体活动的影响。网络环境下人的身体活动受到限制,因而其认知活动与非网络环境存在很大的差异。本研究目的在于考察人们对网络词语与非网络的日常词语的时间知觉,空间距离知觉与知觉范围是否有差异。结果发现被试对网络词语的时间知觉更长;网络词语的空间距离感与日常词语没有显著差异;在启动网络词语之后,被试的知觉范围缩小,对中心刺激的反应显著快于边缘刺激。本研究发现了网络词语加工在时间知觉和知觉范围上的变化。     

拓扑几何在知觉组织与空间概念形成中的运用

陈霖的拓扑知觉理论运用几何性质解释知觉组织,并强调拓扑性质的优先性——拓扑知觉是其他几何知觉的基础,拓扑知觉先于其他几何知觉发生。皮亚杰的拓扑首位理论认为儿童的空间概念发展顺序为先发展拓扑几何概念,之后再发展射影与欧式几何概念。两大理论都运用拓扑性质来解释心理现象,其研究对象、研究方法存在很大不同,但它们在理论结构上具有高度一致性,对几何学在心理学上的运用有非常重要的启示意义。     

Against Perceptual Conceptualism

This paper is concerned with the question of whether mature human experience is thoroughly conceptual, or whether it involves non-conceptual elements or layers. It has two central goals. The first goal is methodological. It aims to establish that that question is, to a large extent, an empirical question. The question cannot be answered by appealing to purely a priori and transcendental considerations. The second goal is to argue, inter alia by relying on empirical findings, that the view known as ‘state-conceptualism’ is false. We will argue that our experiences do involve non-conceptual elements. That is, a subject may enjoy an experience with a particular phenomenal aspect, without possessing the concept needed for the specification of the content of that aspect, and moreover, without being able to acquire that concept upon having that experience.     

Perceptual experience shapes our ability to categorize faces by national origin: A new other-race effect

People are better at recognizing own-race than other-race faces. This other-race effect has been argued to be the result of perceptual expertise, whereby face-specific perceptual mechanisms are tuned through experience. We designed new tasks to determine whether other-race effects extend to categorizing faces by national origin. We began by selecting sets of face stimuli for these tasks that are typical in appearance for each of six nations (three Caucasian, three Asian) according to people from those nations (Study 1). Caucasian and Asian participants then categorized these faces by national origin (Study 2). Own-race faces were categorized more accurately than other-race faces. In contrast, Asian American participants, with more extensive other-race experience than the first Asian group, categorized other-race faces better than own-race faces, demonstrating a reversal of the other-race effect. Therefore, other-race effects extend to the ability to categorize faces by national origin, but only if participants have greater perceptual experience with own-race, than other-race faces. Study 3 ruled out non-perceptual accounts by showing that Caucasian and Asian faces were sorted more accurately by own-race than other-race participants, even in a sorting task without any explicit labelling required. Together, our results demonstrate a new other-race effect in sensitivity to national origin of faces that is linked to perceptual expertise.     

Doing emotions: The role of culture in everyday emotions

Emotional experience is culturally constructed. In this review, we discuss evidence that cultural differences in emotions are purposeful, helping an individual to meet the mandate of being a good person in their culture. We also discuss research showing that individual’s fit to the cultural emotion norm is associated with well-being, and suggest that this link may be explained by the fact that normative emotions meet the cultural mandate. Finally, we discuss research that sheds light on some of the collective processes of emotion construction: social interactions and emotion representations are geared towards promoting emotions that are conducive to the cultural mandate. In conclusion, we suggest that individuals become part of their culture by “doing emotions” in a way that is consistent with the cultural mandate, and that in intercultural interactions, emotions can be literally “at cross purposes”: each person’s emotions are constructed to fit the purposes of their own culture.     

Chisholm on Perceptual Knowledge: Foundationalism versus Coherentism

Abstract: Chisholm refuted phenomenalism as a theory of the justification of perceptual beliefs. He argued, following Thomas Reid, that some perceptual beliefs were justified in themselves, which provided a foundation for empirical knowledge. The question that remains is whether the foundational justification provided offers an adequate explanation of how justification is connected with truth. The search for a truth connection led me from foundationalism to a coherence theory of justification that, contrary to my intentions, was inspired by an observation of Chisholm himself.     

Emotional collectives: How groups shape emotions and emotions shape groups

Group settings are epicentres of emotional activity. Yet, the role of emotions in groups is poorly understood. How do group-level phenomena shape group members’ emotional experience and expression? How are emotional expressions recognised, interpreted and shared in group settings? And how do such expressions influence the emotions, cognitions and behaviours of fellow group members and outside observers? To answer these and other questions, we draw on relevant theoretical perspectives (e.g., intergroup emotions theory, social appraisal theory and emotions as social information theory) and recent empirical findings regarding the role of emotions in groups. We organise our review according to two overarching themes: how groups shape emotions and how emotions shape groups. We show how novel empirical approaches break important new ground in uncovering the role of emotions in groups. Research on emotional collectives is thriving and constitutes a key to understanding the social nature of emotions.     

Going with your gut: How William James' theory of emotions brings insights to risk perception and decision making research

The basic premise of William James' theory of emotions – that bodily changes lead to emotional feelings – ignited debate about the relative importance of bodily processes and cognitive appraisals in determining emotions. Similarly, theories of risk perception have been expanding to include emotional and physiological processes along with cognitive processes. Taking a closer look at The Principles of Psychology, this article examines how James' propositions support and extend current research on risk perception and decision making. Specifically, James (1) described emotional feelings and their related cognitions in ways similar to current dual processing models; (2) defended the proposition that emotions and their expressions serve useful and adaptive functions; (3) suggested that anticipating an emotion can trigger that emotion due to associations learned from past experiences; and (4) highlighted individual differences in emotional experiences that map on well with individual differences in risk-related decision making.

知觉整体优先性的研究及其进展

知觉的性质是整体的还是分析的 ?这是心理学家们长期争论不休的问题。本世纪 70年代以来 ,一些认知心理学家提出知觉加工的整体优先性假设 ,强调整体在知觉加工中的优先地位。这一假设激发了大量整体 /局部范例的研究。本文综述了这方面的研究 ,分析了它们的理论假设 ,指出了这方面研究的局限以及替代的探讨。     

从实践主体谱系看原则主义的缺陷及失根危机——兼论“立心”和“感性大我”之培养的紧迫性

医学伦理的原则主义在实践中体现了工具化和无力性。区分生命需要和片面的生存性需要的基础上给出了人的实践主体谱系,即感性小我、纯粹理性大我和感性大我。其中,只有感性大我是由生命性意志这种自由意志推动的具有独立人格的道德主体。上述缺陷的根本原因在于现代性的道德哲学的失根危机,即失去了可以产生感性大我的人之存在与道德的共同基础,也即真正的“良心”。在崭新的存在论基础上给出了此种良心的知识。当代巨大的科技力量急切期待真正的道德回应,由此凸显了“立心”从而培养“感性大我”的紧迫性,也即人类文明再启蒙的紧迫性。

     

The irrationality of recalcitrant emotions

A recalcitrant emotion is one which conflicts with evaluative judgement. (A standard example is where someone is afraid of flying despite believing that it poses little or no danger.) The phenomenon of emotional recalcitrance raises an important problem for theories of emotion, namely to explain the sense in which recalcitrant emotions involve rational conflict. In this paper I argue that existing ‘neojudgementalist’ accounts of emotions fail to provide plausible explanations of the irrationality of recalcitrant emotions, and develop and defend my own neojudgementalist account. On my view, recalcitrant emotions are irrational insofar as they incline the subject to accept an evaluative construal that the subject has already rejected.

The sufficiency and necessity of appraisals for negative emotions

Past appraisal studies have shown that single appraisals are neither sufficient nor necessary for emotions but no study has examined the same issue with appraisal configurations (combinations of different single appraisals). Undergraduate participants repeatedly indicated their negative emotions (anger, sadness, fear, and guilt) and relevant appraisals as they occurred, or immediately after, in their everyday environments. The results not only replicated past findings on single appraisals but also suggested that appraisal configurations are neither sufficient nor necessary for these negative emotions.
