The purpose of this study was to investigate performance of developmentally delayed preschoolers on intramodal and intermodal matching tasks in the visual and haptic modalities. The performance of these preschoolers was compared with the learning profile of handicapped children. Further analysis determined the relationship between performance on intra- and intermodal matching tasks and scores on visual motor integration and cognitive matching. Eighteen developmentally delayed preschoolers from ages 3.4 years to 5.11 were involved in four matching conditions: visual-visual, haptic-haptic (intramodal), visual-haptic, and haptic-visual (intermodal). Results of this study indicated that accuracy in all modalities increased as chronological age increased. The learning profile of developmentally delayed preschoolers differed from that of nonhandicapped children: the delayed children scored highest on the haptic-visual task, with the visual-haptic and visual-visual scores only slightly lower, but the haptic-haptic scores markedly lower. No meaningful relationship was apparent between performance in the four modalities and cognitive matching and visual motor integration.
