The Dynamics of Simple and Complex Movement Coordination Development in Children Between the Age of 7 and 14.

Thanks to a long term experiment on children between the age of 7 and 14, it was possible to state that the development of hand to eye coordination based on speed of reaction to simple and complex stimuli has a similar trend. This is confirmed by the estimated relationships between the analyzed variables and the age of tested children with the use of correlation coefficients and linear regression. The research material included 679 children (285 females and 394 males) between the age of 7 and 14 years. The testing procedures included two motor tasks, a single simple motor task and a complex one, both evaluated electronically by time. In case of both types of movements the developmental trend was similar.
