RESUMO

The purpose of this study was to verify the effects of the manipulation of information, visual from a moving room, verbal informing about the movement of the room and about a requested action, in body sway of children and adults. Participated of this study 20 children and 20 young adults, who stood upright inside of a moving room. The results revealed that the system intrinsic dynamics, regarding the relationship between visual information and body sway, is not easily modified by behavioral information. The manipulation of the types of verbal information, about the moving room?s movement and requesting a specific action, alters the relationship between visual information and body sway in the moving room situation. However, this change requires the participants continuous attention and, moreover, requesting an action is more effective than only the information about what is happening. Finally, there are behavioral changes in how these different types of information are used for the control of a motor action. While young adults use the provided information in a more appropriate way to perform the requested action, children show difficulty in order to use the provided information or to accomplish an action requested due to the intrinsic dynamics of the system.
