title: Auditory syntactic comprehension in nine aphasia groups (with CT scans) and children: differences in degree but not order of difficulty observed.
abstract: Auditory syntactic comprehension was examined in nine groups of aphasics (60 stroke cases) and 3 and 6 year old children. Ten syntactic contrast pairs were studied. Differences in degree but not order of difficulty were observed. The 5 easier pairs were Gender; On/Under; Negative/Affirmative; Object-number; Subject-number; the 5 more difficult pairs were Past/Present; Subject/Object Reversible; Is/Are; Relative Clause; and Future/Present. The "marked" half-pair was significantly more difficult--i.e., Negative vs. Affirmative; Plural vs. Singular Subject; Future or Past vs. Present. Performance on the test was significantly correlated with the BDAE Auditory Comprehension z-score and Token Test. The 3 year old children most closely resembled the Severe Wernicke's (but were better than the Globals), and the 6 year old children were similar to aphasia cases with mild comprehension deficits and frontal or parietal perisylvian lesions which spared most of Wernicke's area. Wernicke's area (posterior two-thirds superior temporal gyrus area) appears to be the area most sensitive to auditory syntactic comprehension. However, the surrounding perisylvian areas including frontal and parietal lobes are also areas sensitive to syntactic comprehension.
