dc.description.abstractThe present study investigated anomalous hemispheric processing for language and its impact on spatial task performance. Mental rotation and dichotic listening tasks were administered to three groups of children: control (C), learning disabled (LD), and Down syndrome (DS). Significant differences were found in reaction time and accuracy measures in mental rotation. Although the DS group lacked a systematic reaction time function, all three groups produced similar accuracy functions: each group appeared to demonstrate difficulty at equivalent angular disorientations. Dichotic listening resulted in performance differences only when the DS group was compared to the C and LD groups: discrepant language processing was not demonstrated between the C and LD groups. Conclusions could not be reached regarding the impact of language lateralization on spatial task performance. Inconsistencies of neuropsychological measurements are discussed; the topic of mental rotation is explored in depth. Generalizations regarding performance outcomes are limited to a behavioral level.
