Ten cerebellar patients were compared to 10 control subjects on a verbal working memory task in which the phonological similarity of the words to be remembered and their modality of presentation were manipulated. Cerebellar patients demonstrated a reduction of the phonological similarity effect relative to controls. Further, this reduction did not…

In this paper, we reconsider some of the processes that distinguish production and comprehension. In particular, we discuss the specific forms of thinking involved in each: "thinking for speaking" and "thinking for listening" (Black and Chiat, 2000; Slobin, 1996). We argue that thinking for speaking (or for any form of language output) crucially…

This qualitative study investigated written discourse in the form of personal letters written by ten people with aphasia following stroke and ten people with cognitive-language disorder as a consequence of traumatic brain injury, and compared their performance with 15 non brain-damaged writers. Personal letters perform the dual function of…

Patients with corticobasal degeneration (CBD) appear to have impaired number knowledge. We examined the nature of their number deficit while we tested the hypothesis that comprehension of larger numbers depends in part on verbal mediation. We evaluated magnitude judgments and performance on number conservation measures rooted in Piagetian theory…

This paper offers evidence for the Isomorphic Mapping Hypothesis, which holds that individuals with agrammatic aphasia tend to have difficulty comprehending sentences in which the order of NPs is not aligned with the structure of the corresponding event. We begin by identifying a set of constructions in English and Korean for which the IMH makes…

The current study addresses the debate between so-called "structural" and "processing limitation" accounts of aphasia, i.e., whether language impairments reflect the "loss" of linguistic knowledge or its representations, or instead reflect a limitation in processing resources. Confrontation-naming task and category-judgment tasks were used to…

Purpose: This study examined whether the intraoral transducers used in electromagnetic articulography (EMA) interfere with speech and whether there is an added risk of interference when EMA systems are used to study individuals with aphasia and apraxia. Method: Ten adult talkers (5 individuals with aphasia/apraxia, 5 controls) produced 12 American…

The effect of syntax training on the sentence production of four adults with Broca's aphasia was examined. Generalization and maintenance were measured, and naive judges rated "adequacy" of responses. Findings indicated that effects are limited to the grammatical constructions taught, and that effects on response adequacy may be limited.…

The article addresses the use of sign language and drama with young children with such disabilities as mental retardation, aphasia, autism, and other language learning disorders. Examples of activities that integrate creative drama techniques with sign language techniques are offered. (DB)

A study of a brain-damaged subject's impaired performance on tasks involving production of verbal numbers found that lexical errors occurred in spoken production but not in written production, while syntactic error occurred in both modes. (Author/CB)

Nonfluent and fluent dysphasic subjects (N=22) and nondysphasic subjects (N=20) were assessed on tasks of word fluency and picture-naming. Results showed that clinical language examinations should utilize contexts other than naming tasks for detecting the presence of word retrieval problems and for differentiating the two polar types of dysphasia.…

This article explores a model of lexicalisation based upon the constraints that lexicalisation is an interactive process and that it takes place in two stages. The article examines in depth the time-course of normal lexicalisation, speech error data, and the cognitive neuropsychology of speech production. (16 references) (CK)

Explores the neural and hormonal basis of human intellectual function that gives rise to sex differences in the brain. Discusses behavioral, neurological, endocrinological studies, and studies of the effects of hormones on brain functioning that show a relationship between cognitive variations and sex. (MCO)

Two groups of 10 adult aphasics received auditory-verbal "yes-no" questions, including egocentric, environmental, pictorial, and relationship items, either in a consistent order or random order. Support was found for the existence of a hierarchy of difficulty among the types of questions, but there was no significant difference between…

This study of four moderately to severely aphasic subjects found that success in manual sign training programs is related to severity of aphasia, that aphasic subjects' propositional use of manual signs rarely follows simple acquisition, and that generalization to untrained stimuli or environments does not occur without additional training.…
