[Experimental analysis of the contralaterally associated-movements with the finger task movements (author's transl)].
To investigate features of the contralaterally associated-movements (AM) in connection with the main movements, 6-year-old children were asked to play "marbles" as the main movements, and both its performance and AM were checked. The first analysis indicated that AM contained two different movements, pre-associated-movements (PAM) and simultaneously associated movements (SAM). PAM and SAM showed different features in relation to their directions, changes through trial blocks and right-left-balances. When classified into three groups on the basis of their performance of the main movements, the subjects in the low group showed the maximum AM in both PAM and SAM. Furthermore, the kind of SAM patterns decreased in inverse proportion to performance level.
