title: Spatial and emotional aspects of language inferencing in nonverbal learning disabilities.
abstract: Although subtle linguistic deficits have been postulated for children identified with nonverbal learning disabilities (NLD), there is little empirical evidence to support this contention. Two experimental language inferencing measures that have been demonstrated to be problematic for individuals with right hemisphere brain damage (RHBD) and one norm-referenced inferencing task were examined in three groups of children aged 9-13: (1) children with NLD (n = 14), (2) children with verbal impairments (VI) (n = 14), and (3) children without learning disabilities who served as controls (n = 19). The NLD and VI groups did not differ from one another on any of the three measures, indicating a generalized language inferencing deficit in the NLD group. Relative to the control group, however, the NLD group experienced specific difficulties with spatial and emotional inferencing. The implications for right hemisphere involvement in the NLD profile are examined in relation to the effects of working memory on inferential abilities.
