The use of a traditional syndrome-classification system for aphasics is examined critically from the different perspectives of medicine and psychometrics. Medicine views syndromes as dichotomous (present or not present) and necessarily indicative of an underlying pathognomic state or process, and psychometrics sees performances as varying along a…

This work is an English translation of the author's classic "Kindersprache, Aphasie und allgemeine Lautgesetze," first published in 1941. It is considered the most representative and comprehensive of the author's phonological writings, dealing not only with phonological typology but related problems of language acquisition and phonemic regression…

This paper examines the perceptual processes that underlie normal language acquisition with relation to perceptual dysfunctions in the aphasic child. Experiments are cited which seem to indicate that auditory dyfunctions may underlie language impairment. Experimental studies of the linguistic systems of the aphasic child seem to support the theory…

This paper describes the results of two studies of auditory processing in child aphasia, and their implication for understanding deviant language development. The term "aphasia" is discussed as it is used to describe adult and child language disorders. A first experiment on the auditory functioning in aphasic and nonaphasic children suggests that…

The methodological soundness of a number of communicational models is tested for relevance to communicative disorders. Existing models lack isomorphism in relating environment to language structure. A new model, useful in classification of communicative disorders, is proposed, tested, and found to encompass (1) an indication that language is a…

The Psychotic Behavior Rating Scale uses a factor analysis approach to aid in differential diagnosis of autism, schizophrenia, mental retardation, aphasia, and other severe handicaps. The scale is compared with five existing qualitatively developed instruments, noting similarities and dissimilarities among the various scales. (Author/JDD)

Discusses recent studies of aphasia from the perspective of theories of normal language structure and processing. Patterns of language breakdown are considered to reflect the componential structure of the language system. Brain damage is seen to fractionate language along lines suggested by existing psycholinguistic models. (Author)

Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

Two studies are reported in which the following theory is tested: the agrammatic sentence form that is observed in the spontaneous speech of Broca's aphasics is attributable to the selection of elliptical syntactic structures in which the slots for many of the closed-class words that appear in complete sentences are lacking. (54 references)…

Notes that in linguistic theory, phenomena previously handled by a separate grammatical component have been moved into the lexicon and that in some theories, the contrast between grammar and the lexicon has vanished. Concludes that the case for a modular distinction between grammar and the lexicon has been overstated and that the evidence to date…

This article presents an approach to a variety of syndromes and patterns of language disorders in bilingual speakers and polyglots. This framework demands that in neuropsychological analysis, all the variables and dynamics of bilingual development have to be taken into consideration, along with details of the neurological syndrome. (Contains…

Reading and writing deficits in two multilingual speakers of Kannada, Hindi and English are described. Disorders of the two patients (Mr G and Ms S) had different etiologies. Mr G had severe alexia with agraphia in English as well as in Kannada and Hindi. Ms S exhibited dissociation across the languages, showing symptoms of surface dyslexia in…

Aphasia implies the loss or impairment of language caused by brain damage. The key to understanding the nature of aphasic symptoms is the neuro-anatomical site of brain damage, and not the causative agent. However, because "Herpes simplex" virus (HSV) encephalitis infection usually affects the frontal and temporal lobes, subcortical…

This book provides an overview of the causes and symptoms, and the typical courses, treatments, and outcomes of neurogenic communication disorders. Chapter 1 reviews the human nervous system and neurologic causes of adult communication disorders. Chapter 2 discusses the neurologic assessment and arriving at a diagnosis, including the neurologist's…

Vertical and lateral integration are two important nervous system integrations that affect the development of oral behaviors. There are three progressions in the vertical integration process for speech nervous system development: R-complex speech (ritualistic, memorized expressions), limbic speech (emotional expressions), and cortical speech…
