Hand and Mind: What Gestures Reveal about Thought

Abstract: What is the relation between gestures and speech? In terms of symbolic forms, of course, the spontaneous and unwitting gestures we make while talking differ sharply from spoken language itself. Whereas spoken language is linear, segmented, standardized, and arbitrary, gestures are global, synthetic, idiosyncratic, and imagistic. In Hand and Mind, David McNeill presents a bold theory of the essential unity of speech and the gestures that accompany it. This long-awaited, provocative study argues that the unity of gestures and language far exceeds the surface level of speech noted by previous researchers and in fact also includes the semantic and pragmatic levels of language. In effect, the whole concept of language must be altered to take into account the nonsegmented, instantaneous, and holistic images conveyed by gestures. McNeill and his colleagues carefully devised a standard methodology for examining the speech and gesture behavior of individuals engaged in narrative discourse. A research subject is shown a cartoon like the 1950 Canary Row--a classic Sylvester and Tweedy Bird caper that features Sylvester climbing up a downspout, swallowing a bowling ball and slamming into a brick wall. After watching the cartoon, the subject is videotaped recounting the story from memory to a listener who has not seen the cartoon. Painstaking analysis of the videotapes revealed that although the research subjects--children as well as adults, some neurologically impaired--represented a wide variety of linguistic groupings, the gestures of people speaking English and a half dozen other languages manifest the same principles. Relying on data from more than ten years of research, McNeill shows thatgestures do not simply form a part of what is said and meant but have an impact on thought itself. He persuasively argues that because gestures directly transfer mental images to visible forms, conveying ideas that language cannot always express, we must examine language and gesture

Gesture and Thought

Abstract: Gesturing is such an integral yet unconscious part of communication that we are mostly oblivious to it. But if you observe anyone in conversation, you are likely to see his or her fingers, hands, and arms in some form of spontaneous motion. Why? David McNeill, a pioneer in the ongoing study of the relationship between gesture and language, set about answering this question in "Gesture and Thought" with an unlikely accomplice - Tweety Bird. McNeill argues that gestures are active participants in both speaking and thinking. He posits that gestures are key ingredients in an "imagery-language dialectic" that fuels speech and thought; gestures are the "imagery" and also the components of "language," rather than mere consequences. The smallest unit of this dialectic is the "growth point," a snapshot of an utterance at its beginning psychological stage. Enter Tweety Bird. In "Gesture and Thought", the central growth point comes from a cartoon. In his quest to eat Tweety Bird, Sylvester the cat first scales the outside of a rain gutter to reach his prey. Unsuccessful, he makes a second attempt by climbing up the inside of the gutter. Tweety, however, drops a bowling ball down the gutter; Sylvester swallows the ball. Over the course of twenty-five years, McNeill showed this cartoon to numerous subjects who spoke a variety of languages. A fascinating pattern emerged. Those who remembered the exact sequence of the cartoon while retelling it all used the same gesture to describe Sylvester's position inside the gutter. Those who forgot, in the retelling, that Sylvester had first climbed the outside of the gutter did not use this gesture at all. Thus that gesture becomes part of the "growth point" - the building block of language and thought. An ambitious project in the ongoing study of the relationship of how we communicate and its connection to thought, "Gesture and Thought" is a work of such consequence that it will influence all subsequent linguistic and evolutionary theory on the subject.

A spreading-activation theory of semantic processing

Abstract: This paper presents a spreading-acti vation theory of human semantic processing, which can be applied to a wide range of recent experimental results The theory is based on Quillian's theory of semantic memory search and semantic preparation, or priming In conjunction with this, several of the miscondeptions concerning Qullian's theory are discussed A number of additional assumptions are proposed for his theory in order to apply it to recent experiments The present paper shows how the extended theory can account for results of several production experiments by Loftus, Juola and Atkinson's multiple-category experiment, Conrad's sentence-verification experiments, and several categorization experiments on the effect of semantic relatedness and typicality by Holyoak and Glass, Rips, Shoben, and Smith, and Rosch The paper also provides a critique of the Smith, Shoben, and Rips model for categorization judgments Some years ago, Quillian1 (1962, 1967) proposed a spreading-acti vation theory of human semantic processing that he tried to implement in computer simulations of memory search (Quillian, 1966) and comprehension (Quillian, 1969) The theory viewed memory search as activation spreading from two or more concept nodes in a semantic network until an intersection was found The effects of preparation (or priming) in semantic memory were also explained in terms of spreading activation from the node of the primed concept Rather than a theory to explain data, it was a theory designed to show how to build human semantic structure and processing into a computer

Human memory ; A proposed system and its control processes

Abstract: Publisher Summary This chapter presents a general theoretical framework of human memory and describes the results of a number of experiments designed to test specific models that can be derived from the overall theory. This general theoretical framework categorizes the memory system along two major dimensions. The first categorization distinguishes permanent, structural features of the system from control processes that can be readily modified or reprogrammed at the will of the subject. The second categorization divides memory into three structural components: the sensory register, the short-term store, and the long-term store. Incoming sensory information first enters the sensory register, where it resides for a very brief period of time, then decays and is lost. The short-term store is the subject's working memory; it receives selected inputs from the sensory register and also from long-term store. The chapter also discusses the control processes associated with the sensory register. The term control process refers to those processes that are not permanent features of memory, but are instead transient phenomena under the control of the subject; their appearance depends on several factors such as instructional set, the experimental task, and the past history of the subject.

Parkinson’s disease: clinical features and diagnosis

Abstract: Objective: Parkinson’s disease (PD) is a progressive neurological disorder characterised by a large number of motor and non-motor features that can impact on function to a variable degree. This review describes the clinical characteristics of PD with emphasis on those features that differentiate the disease from other parkinsonian disorders. Methods: A MedLine search was performed to identify studies that assess the clinical characteristics of PD. Search terms included “Parkinson’s disease”, “diagnosis” and “signs and symptoms”. Results: Because there is no definitive test for the diagnosis of PD, the disease must be diagnosed based on clinical criteria. Rest tremor, bradykinesia, rigidity and loss of postural reflexes are generally considered the cardinal signs of PD. The presence and specific presentation of these features are used to differentiate PD from related parkinsonian disorders. Other clinical features include secondary motor symptoms (eg, hypomimia, dysarthria, dysphagia, sialorrhoea, micrographia, shuffling gait, festination, freezing, dystonia, glabellar reflexes), non-motor symptoms (eg, autonomic dysfunction, cognitive/neurobehavioral abnormalities, sleep disorders and sensory abnormalities such as anosmia, paresthesias and pain). Absence of rest tremor, early occurrence of gait difficulty, postural instability, dementia, hallucinations, and the presence of dysautonomia, ophthalmoparesis, ataxia and other atypical features, coupled with poor or no response to levodopa, suggest diagnoses other than PD. Conclusions: A thorough understanding of the broad spectrum of clinical manifestations of PD is essential to the proper diagnosis of the disease. Genetic mutations or variants, neuroimaging abnormalities and other tests are potential biomarkers that may improve diagnosis and allow the identification of persons at risk.
