基础认知与社会认知中内隐过程及其脑机制*

认知过程及其脑机制是心理学研究的重要内容。社会认知是人们在社会生活中对他人行为的意图及情感的认识,是人际互动的重要方面,具有深刻的理论和实践意义。本文全面深入地对社会认知和基础认知中自动加工过程进行了研究综述,对基础认知与社会认知的研究方式进行了比较。自动加工过程是社会认知和基础认知中都存在的重要过程,从脑机制研究角度,相关的电生理学指标(如N400等)都可以作为研究的指标来考察社会认知中的自动加工过程。本文从社会认知与基础认知的比较入手,介绍了各种领域的研究方法,特别是事件相关电位技术等认知神经科学研究方法。     

Cognition and motivation in emotion

The role of cognition--and to some extent motivation--in emotion, the ways meaning is generated, unconscious appraising, and the implications of this way of thinking for life-span development are addressed. It is argued that appraisal is a necessary as well as sufficient cause of emotion and that knowledge is necessary but not sufficient. This position is examined in light of what is known about emotions in infants and young children, the effects of drugs on acute emotions and moods, and recent patterns of thought about the brain in emotions. The discussion of how meaning is generated is the core of the article. Automatic processing without awareness is contrasted with deliberate and conscious processing, and the concept of resonance between an animal's needs and what is encountered in the environment is examined. The idea that there is more than one way meaning is achieved strengthens and enriches the case for the role of appraisal in emotion and allows the consideration of what is meant by unconscious and preconscious appraisal and the examination of how they might work.     

Cognition in music

A cognitive/constructive view of music is put forth that diverges from traditional conceptions of music (e.g., music as sound; music as behavior; music as communication). The present view attempts to be compatible with the evidence of historic style changes that have occurred in the notated repertory of Western music. Two levels of cognitive processing are proposed: processes on the level of particular styles (germane to a certain period, culture, or community) and processes that are generic, universal, or cross-stylistic. Twelve such generic processes are described in detail. Several problems in the research stemming from earlier definitions of music are explored. In particular, attention is given to the artifacts of theoretical analysis (e.g., scales, chords, and discrete pitches) and their influence on music-psychological research.     

Affect and Cognition

ABSTRACT— One of the greatest puzzles of human nature concerns the poorly understood interplay between affect and cognition—the rational and emotional ways of dealing with the social world around us. Affect is a ubiquitous and powerful phenomenon in our lives, yet research on human affectivity has been neglected until quite recently. This article reviews traditional and contemporary approaches to this issue, and recent theoretical and empirical work exploring the links between affect and cognition is considered. The major achievements and shortcomings of this now-thriving research area are discussed, and the future prospects of psychological research on human affectivity are considered.     

Animal Cognition: The Bridge BetweenAnimal Learning and Human Cognition

Carefully controlled research with animals has demonstrated cognitive capacities for which traditional theories of associative learning cannot account. One example is the symbolic representation of stimuli. If two arbitrary stimuli are associated with a third event, an emergent relation can be shown to develop. A second example is the ability of animals to plan ahead, and to choose whether to plan ahead or not. Although animals have often been used to model drug effects in humans, these models have rarely been used to examine the effects of drugs on cognitive functioning. Furthermore, examination of the effects of drugs on the cognitive behavior of animals may help to identify the nature of the representations underlying the cognition.     

Affect and Cognition in Party Identification

Despite the centrality of party identification in understandings of political behavior in the United States, there is an unacknowledged disparity between our theories and measurement of the phenomenon. The traditional method of measuring party identification relies on supplying cognitive cues by explicitly asking respondents to "think" about their partisanship. The Michigan theory of party identification, in contrast, assumes that partisanship is primarily affective. Using a survey experiment, we explore the effects of asking respondents to feel rather than think about their party identification. The new questions reveal that the electorate is more Republican than previously thought. Response timers show that respondents take longer to answer the new items, suggesting that they are surveying a wider and deeper array of considerations. These results serve to revive many of our traditional conceptions of how party identity works while also opening the door for new research questions.

Force Dynamics in Language and Cognition

"Force dynamics" refers to a previously neglected semantic category—how entities interact with respect to force. This category includes such concepts as: the exertion of force, resistance to such exertion and the overcoming of such resistance, blockage of a force and the removal of such blockage, and so forth. Force dynamics is a generalization over the traditional linguistic notion of "causative": it analyzes "causing" into finer primitives and sets it naturally within a framework that also includes "letting," "hindering," "helping," and still further notions. Force dynamics, moreover, appears to be the semantic category that uniquely characterizes the grammatical category of modals, in both their basic and epistemic usages. In addition, on the basis of force dynamic parameters, numerous lexical items fall into systematic semantic patterns, and there exhibit parallelisms between physical and psychosocial reference. Further, from research on the relation of semantic structure to general cognitive structure, it appears that the concepts of force interaction that are encoded within language closely parallel concepts that appear both in early science and in naive physics and psychology. Overall, force dynamics thus emerges as a fundamental notional system that structures conceptual material pertaining to force interaction in a common way across a linguistic range: the physical, psychological, social, inferential, discourse, and mental-model domains of reference and conception.     

Cognition About Cognition: Metacognitive Therapy and Change in Generalized Anxiety Disorder and Social Phobia

Metacognitive theory and therapy views the persistence of negative beliefs and thoughts as a result of metacognitions controlling cognition. This paper describes, with reference to the treatment of generalized anxiety disorder (GAD) and social phobia, how metacognition contributes to cognitive stability and to change. Metacognitive therapy offers a level of formulation and intervention that does not focus predominantly on challenging the content of negative thoughts and beliefs that are emphasized in traditional cognitive therapy. The focus of treatment in GAD is on erroneous beliefs about worry and unhelpful mental regulation strategies. In treating social phobia, a greater emphasis is placed on modifying attention and worry processes and on configuring processing during and after behavioral experiments.     

Leaders in Reading Research and Instruction

For many years researchers in psychology and education have studied differences in the way individuals perceive, organize and “make sense” of environmental stimuli. These rather stable individual differences, termed cognitive styles, appear to relate to many aspects of reading behavior. This paper explores how findings from current cognitive styles research might enlighten researchers in reading process and reading instruction. Particular attention is directed toward reading comprehension processes and instructional task variables.     

Reasoning and Instruction in Medical Curricula

We describe two experiments that examine the knowledge and explanatory processes of students in two medical schools with different modes of instruction. One school had a conventional curriculum with basic science courses taught 1 '/2 years before the clinical training; the other had a problem-based learning curriculum with basic science taught in the context of clinical problems and general problem-solving strategies involving knowledge elaboration and hypothetico-deductive reasoning. Both before and after being exposed to relevant basic science information, students were asked to provide diagnostic explanations of a clinical case. In this study, students in the problem-based learning curriculum reasoned in a manner consistent with the way they were taught, using a backward directed pattern of reasoning and extensive elaborations based on detailed biomedical information. However; these students had a greater tendency to commit errors of scientific fact, to generate less coherent explanations, and to use flawed patterns of explanation, such as circular reasoning. These results are viewed as reflecting the operation of two factors: context and method of instruction. The interaction between these factors is expressed in terms of the hypothesis that basic science and clinical knowledge constitute two different worlds.     

Cognition and hearing aids

The perceptual information transmitted from a damaged cochlea to the brain is more poorly specified than information from an intact cochlea and requires more processing in working memory before language content can be decoded. In addition to making sounds audible, current hearing aids include several technologies that are intended to facilitate language understanding for persons with hearing impairment in challenging listening situations. These include directional microphones, noise reduction, and fast-acting amplitude compression systems. However, the processed signal itself may challenge listening to the extent that with specific types of technology, and in certain listening situations, individual differences in cognitive processing resources may determine listening success. Here, current and developing digital hearing aid signal processing schemes are reviewed in the light of individual working memory (WM) differences. It is argued that signal processing designed to improve speech understanding may have both positive and negative consequences, and that these may depend on individual WM capacity.
