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)

This article presents a linguistic description of the phenomenon of dyssyntaxia. (Text is in French.) (CLK)

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.…
