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.     

Reflex theory in a linguistic context: Sergej M. Dobrogaev on the social nature of speech production

The development of reflex theory in its Pavlovian interpretation had significant resonance in a wide range of academic research areas. Its impact on the so-called humanities was, perhaps, no less than the effect it had in medical science. The idea of the conditioned reflex suggesting a physiological explanation of behaviour patterns received a particularly warm welcome in philosophy and psychology as it provided a scientifically-based tool for a conceptual u-turn towards objectivism. This article looks into the ways these ideas contributed to the formation of the Soviet language theory, namely, to the sociological interpretation of language development and speech production presented in the pioneering works of Sergej M. Dobrogaev (1873–1952).

ANIMALIA,HOMO, AND THE KINGDOM OF GOD

Abstract. I selectively and critically review the state of knowledge about human evolution and the place of humans vis‐à‐vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven.     

言语产生过程中语义、语音激活的ERP研究

使用ERP技术考察了言语产生过程中语音和语义的激活情况。图片上有3种条件的干扰词,分别与目标图片名称形成3种关系:语义相关,语音相同,语义、语音、字形都不相关。结果显示,当被试执行延迟命名任务(实验1)时,与目标图片名称语义相关和控制条件的波形比语音相关的波形更趋于负向。说明在图片命名过程中语音有明显的促进作用。当要求被试对上述图片进行延迟语义判断任务(实验2)时,与目标图片名称语义相关、语音相关及控制条件的波形之间无明显差异。说明在语义提取过程中没有语音的促进作用。综合实验1和实验2,本研究的结果更倾向于支持独立两阶段模型。     

Signature tunes in mothers' speech to infants

The purpose of the present investigation was to determine whether mothers use discernible tunes (i.e., specific interval sequences) in their speech to infants and whether such tunes are individually distinctive. Mothers were recorded speaking with their infants on two occasions separated by 1 week or more. Examination of the tunes of each mother revealed discernible tunes and frequent repetitions of tunes within and across sessions. Comparisons of utterances with the most common pitch contour (i.e., rising), both within and across mothers, revealed interval patterns that were individually distinctive, or unique. The findings confirm the prominence of tunes and the presence of signature tunes in maternal speech to infants.     

Beyond babytalk: Re-evaluating the nature and content of speech input to preverbal infants

Infant-directed maternal speech is an important component of infants’ linguistic input. However, speech from other speakers and speech directed to others constitute a large amount of the linguistic environment. What are the properties of infant-directed speech that differentiate it from other components of infants’ speech environment? To what extent should these other aspects be considered as part of the linguistic input? This review examines the characteristics of the speech input to preverbal infants, including phonological, morphological, and syntactic characteristics, specifically how these properties might support language development. While maternal, infant-directed speech is privileged in the input, other aspects of the environment, such as adult-directed speech, may also play a role. Furthermore, the input is variable in nature, dependent on the age and linguistic development of the infant, the social context, and the interaction between the infant and speakers in the environment.     

From Figure to Argument: <Emphasis Type="Italic">Contrarium</Emphasis> in Roman Rhetoric

In Roman rhetoric, contrarium was variably considered either a figure of speech or an argument. The paper examines the logical pattern of this type of argument, which according to Cicero is based on a third Stoic indemonstrable syllogism: The persuasiveness of this type of argument, however, vitally depends on the validity of the alleged ‹incompatibility’ forming its major premiss. Yet this appears to be the argument’s weak point, as the ‹incompatibilities’ employed generally hold for the most part only, and are reducible to topical argument schemes. This is why in practical usage such arguments are most often phrased as rhetorical questions, the persuasive force of which, enhanced by certain strategical maneuverings and fallacies, makes the audience swallow the argument.
