Abstract
We developed a training material using the 3-dimensional construction of colored blocks to improve visual reasoning in children with visuospatial cognitive impairment,and performed training using this material in 2 children.Training effects were evaluated using the composite score for the WISC-Ⅳ Perceptual Reasoning.In addition,to compare visuospatial cognition with visual reasoning,the WISC-Ⅳ Block Design score was selected as a parameter for visuospatial cognition,and Matrix Reasoning as a parameter for visual reasoning. After the training,Case 1 showed increases in the Perceptual Reasoning composite score(+17),Block Design score(+2),and the Matrix Reasoning score(+3)and Case 2 also showed increases in the Perceptual Reasoning composite score(+11),Block Design score(+1),and the Matrix Reasoning score(+2).The mean changes in Cases 1 and 2 were +14.0 in the Perceptual Reasoning composite score,+1.5 for the Block Design score,and +2.5 in the Matrix Reasoning score. The mean change(+14.0)for the Perceptual Reasoning composite score in Cases 1 and 2 suggests the effects of the training task in this study.In addition,since the change in the mean score was 1.0 greater for the visual reasoning parameter(Matrix Reasoning,+2.5)than for the visuospatial cognition parameter(Block Design,+1.5),the task used in this study may be useful for improving visual reasoning.
