THE MT-86 BETA APHASIA BATTERY - A SUBSET OF NORMATIVE DATA IN RELATION TO AGE AND LEVEL OF SCHOOL EDUCATION .2.

The MT-86 beta version of the Montreal-Toulouse Aphasia Battery includes 23 subtests for the assessment of both comprehension and production of oral and written speech. The whole battery was administered to a total of 167 neurologically healthy subjects. Normative data for seven of the 23 subtests were reported in a previous study (Beland and Lecours 1990). This study deals with the remaining 16 subtests of the MT-86 beta. Mean scores, standard deviations and score ranges are reported and cut-off scores for eight subtests are suggested. Main effects of both age and education are found in written picture naming and oral picture description subtests. An age effect is observed in the object manipulation subtest, and an education effect in the written word and sentence picture-matching subtest. Significant differences indicate better mean scores among younger versus older adults, and better mean scores among subjects with a higher versus a lower level of school education. Qualitative analyses of error types are also reported.
