Cognitive impairment of aphasics in a colour-to-picture matching task. 1979

R Cohen, and S Kelter

Broca's and Wernicke's aphasics, non-aphasic brain-damaged patients and chronic schizophrenics were tested in a colour-to-picture matching task. For each of 42 black-and-white drawings of objects the most "typical" colour was to be selected from a set of 24 colour strips. Separate scores for the appropriateness of the choices as to hue, brightness, and saturation were obtained by comparison with the data from 50 normal Ss. The choices of both aphasic groups were more deviant than those of brain-damaged controls for chromatically coloured objects with respect to all three colour dimensions, and for achromatically coloured objects with respect to saturation and brightness. Wherever the aphasics' performance was worse than that of the controls, the deviancy-scores correlated significantly with the Token Test. Results are interpreted as an impairment of aphasics in the ability to isolate analytically specific features of objects or concepts which might be conceived of as a prerequisite of propositional language.

D003118	Color Perception	Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.

D001037	Aphasia	A cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. This condition is caused by diseases which affect the language areas of the dominant hemisphere. Clinical features are used to classify the various subtypes of this condition. General categories include receptive, expressive, and mixed forms of aphasia.

D001039	Aphasia, Broca	An aphasia characterized by impairment of expressive LANGUAGE (speech, writing, signs) and relative preservation of receptive language abilities (i.e., comprehension). This condition is caused by lesions of the motor association cortex in the FRONTAL LOBE (BROCA AREA and adjacent cortical and white matter regions).
