title: [A study of constructional activity in patients with cerebrovascular disorders].
abstract: Three experiments were conducted to examine the differences of constructional disabilities between left and right hemiplegic patients with cerebrovascular disorders. In Exp. I, 32 left and 30 right hemiplegics were given the Block Design Test. In Exp. II, the Visual Cognition Test, consisted of 10 subtests to measure the abilities which were presumed to be essential for the process of block design construction, was performed. In Exp. III, the patients with constructional disabilities were given various aids to facilitate the constructional activities. The main results were as follows: Constructional disabilities were more frequent and severe in left than right hemiplegic patients. There were qualitative differences in construction between the two groups. The factors underlying constructional disabilities were responsible to visuoperceptual disorder and programming disorder of behavior for both groups. However, visuoperceptional disorder in left hemiplegics and programming disorder in right hemiplegics manifested relatively closer relation to constructional disabilities than others.
