On the Constitution and the True Aim of The Joy of Heaven and Non-Speech： A Reinterpretation of the Debate at the Dam over the Hao River

The essay starts by questioning how the debate at the dam over the Hao River between Zhuang Zi and Hui Zi arose. It describes the source of ideas that led Zhuang Zi to speak on the enjoyment of the fish (yuzhile 鱼之乐) and points out that the meaning of the debate rests in bringing about the emergence of the true subject of “enjoyment.” It highlights this meaning by analyzing the essential content and value orientation of Zhuang Zi’s ideas on the joy of heaven (tian le 天乐) and perfect enjoyment (zhile 至乐). Following up on this thread, the essay goes further to analyze the true meaning of Zhuang Zi’s theory concerning the “great speech” of “non-speaking.” This essay holds that the debate is a parable, an external representation that unfolds an internal tension between two different levels contained within Zhuang Zi’s thought, rather than simply a debate between these two thinkers.     

失歌症者对音乐和言语音高的加工

音高是音乐和言语领域中一个重要维度。失歌症是一种对音乐音高加工的障碍。探讨失歌症者对音乐和言语音高的加工有助于揭示音乐和言语音高加工是否共享特定的认知和神经机制。已有研究结果表明, 失歌症者对音乐音高加工存在障碍, 这种音高障碍在一定程度上影响到言语音高加工。同时, 声调语言背景无法弥补失歌症者的音高障碍。这些研究结果支持了资源－共享框架(resource-sharing framework), 即音乐和语言共享特定的认知和神经机制(Patel, 2003, 2008, in press), 并可能在一定程度上为失语症临床治疗提供借鉴。     

汉语口语韵律的作用及其神经机制

汉语是一种声调语言, 在口语韵律表达中存在独特的特点。本项目利用汉语不同于非声调语言的特点, 探讨已有研究中尚未澄清的问题, 即汉语声调在早期自动加工中对语义激活的作用, 以及在不同认知阶段中, 汉语声调和语调加工的神经机制。这些问题是当前的研究热点, 但仍存在着各种分歧和激烈的争论。本项目拟采用ERP方法, 结合LORETA源定位技术, 通过不同的实验范式考察以下内容：(1)在早期自动加工过程中, 汉语声调对词汇语义激活的作用; (2)在早期阶段, 汉语声调和语调加工的大脑激活模式; (3)在晚期阶段, 汉语声调和语调加工的大脑激活模式。对这些问题的考察将有助于澄清当前的激烈争论, 拓展以往基于非声调语言研究建立的口语加工理论的适用范围, 为完善言语认知加工的理论模型提供新的实验证据。     

口语句子产生中词汇选择的计划单元：来自大中小学生的比较研究

采用图-词干扰范式,要求被试口语产生包含三个名词的句子,通过检验句中不同位置的名词上的语义干扰效应, 探讨大中小学生言语产生中词汇选择的计划单元。结果发现,大学生和初中生都只在第一个名词上发现了言语产生潜伏期的语义干扰效应,表明其词汇选择的计划单元只限于第一个名词,支持了严格递进假设;小学生在三个名词上都没有发现潜伏期的语义干扰效应,表明小学生没有稳定地选择好第一个名词即开始发音。由此可见,词汇选择的计划单元大小是可变的,存在年龄上的个体差异,主要表现在小学生和初中生之间。     

Getting Vygotskian about theory of mind: Mediation,dialogue, and the development of social understanding

The ideas of Vygotsky [Vygotsky, L. S. (1987). Thinking and speech. In The collected works of L. S. Vygotsky, (Vol. 1). New York: Plenum. (Original work published 1934.)] have been increasingly influential in accounting for social–environmental influences on the development of social understanding (SU). In the first part of this article, I examine how Vygotskian ideas have to date been recruited to explanations of the development of SU. Next, I present a model of SU development which draws on two implications of Vygotsky’s ideas: the importance of semiotic mediation for mental functioning, and the dialogic nature of the higher mental functions. I then consider the value of the proposed model in accounting for evidence from three areas of enquiry: the typical development of SU in infancy and early childhood, relations between individual differences in SU and social–environmental variables, and atypical development. The model is suggested to be particularly helpful in understanding the transition from intentional-agent to mental-agent understanding, and the role of language in SU. Remaining challenges include a need to specify further the cognitive processes underlying internalization, and to gather more extensive evidence on the roles of typical and atypical social experience in SU development.     

Motor programming in apraxia of speech

Apraxia of Speech (AOS) is an impairment of motor programming. However, the exact nature of this deficit remains unclear. The present study examined motor programming in AOS in the context of a recent two-stage model [Klapp, S. T. (1995). Motor response programming during simple and choice reaction time: The role of practice. Journal of Experimental Psychology: Human Perception and Performance, 21, 1015–1027; Klapp, S. T. (2003). Reaction time analysis of two types of motor preparation for speech articulation: Action as a sequence of chunks. Journal of Motor Behavior, 35, 135–150] that proposes a preprogramming stage (INT) and a process that assigns serial order to multiple programs in a sequence (SEQ). The main hypothesis was that AOS involves a process-specific deficit in the INT (preprogramming) stage of processing, rather than in the on-line serial ordering (SEQ) and initiation of movement. In addition, we tested the hypothesis that AOS involves a central (i.e., modality-general) motor programming deficit. We used a reaction time paradigm that provides two dependent measures: study time (the amount of time for participants to ready a motor response; INT), and reaction time (time to initiate movement; SEQ). Two experiments were conducted to examine INT and SEQ in AOS: Experiment 1 involved finger movements, Experiment 2 involved speech movements analogous to the finger movements. Results showed longer preprogramming time for patients with AOS but normal sequencing and initiation times, relative to controls. Together, the findings are consistent with the hypothesis of a process-specific, but central (modality-independent) deficit in AOS; alternative explanations are also discussed.     

Can the irrelevant speech effect turn into a stimulus suffix effect?

The irrelevant sound effect (ISE) and the stimulus suffix effect (SSE) are two qualitatively different phenomena, although in both paradigms irrelevant auditory material is played while a verbal serial recall task is being performed. Jones, Macken, and Nicholls (2004) have proposed the effect of irrelevant speech on auditory serial recall to switch from an ISE to an SSE mechanism, if the auditory-perceptive similarity of relevant and irrelevant material is maximized. The experiment reported here (n = 36) tested this hypothesis by exploring auditory serial recall performance both under irrelevant speech and under speech suffix conditions. These speech materials were spoken either by the same voice as the auditory items to be recalled or by a different voice. The experimental conditions were such that the likelihood of obtaining an SSE was maximized. The results, however, show that irrelevant speech—in contrast to speech suffixes—affects auditory serial recall independently of its perceptive similarity to the items to be recalled and thus in terms of an ISE mechanism that crucially extends to recency. The ISE thus cannot turn into an SSE.     

Speech Perception: Cognitive Foundations and Cortical Implementation

ABSTRACT— Speech perception includes, minimally, the set of computations that transform continuously varying acoustic signals into linguistic representations that can be used for subsequent processing. The auditory and motor subroutines of this complex perceptual process are executed in a network of brain areas organized in ventral and dorsal parallel pathways, performing sound-to-meaning and sound-to-motor mappings, respectively. Research on speech using neurobiological techniques argues against narrow motor or auditory theories. To account for the range of cognitive and neural attributes, integrative computational models seem promising.     

Measuring model flexibility with parameter space partitioning: an introduction and application example

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data-fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general-purpose method for analyzing and comparing all classes of cognitive models. PSP is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.     

The Structure of Self-Consciousness in Children and Young Adolescents and Relations to Social Anxiety

Decades of research have examined the structure of self-consciousness in adults and its relationship to social anxiety. This study examined the structure of self-consciousness via the Self-Consciousness Scales (Fenigstein et al., J. Consult. Clin. Psychol. 43:522–527, 1975) in a school sample of 175 children and young adolescents (92 girls; mean age = 11.5). Confirmatory factor analysis best supported a five-factor solution (Internal State Awareness, Self-Reflectiveness, Appearance Consciousness, Style Consciousness and Social Anxiety). Although some factor based subscales evidenced low internal consistencies, convergent and discriminant correlations with self-report measures of social phobia, negative affect, and positive affect as well as parent-report measures of internalizing and externalizing problems provided additional support for the five-factor model. Future studies should further examine the multidimensional nature as well as the developmental course of self-consciousness and its relation to social anxiety longitudinally.
