Abstract : Since earlier work investigating the problem of target acquisition and positioning adjustment in a homogeneous environment was directed at horizontal accuracy, the present study was conducted in order to define possible relationships between the ability to position a target in the vertical axis and in the horizontal. Four Ss were required to reposition, to geometric center, three targets which originated from six locations, in the vertical axis. In addition, Ss were also required to reposition one of the targets along the horizontal axis. The results for vertical and horizontal accuracy could not be determined separately since vertical and horizontal trials were interspersed in the same experimental series. However, what was shown clearly was that feedback, in terms of knowledge of where geometric center is located, can significantly affect vertical and horizontal positioning. It was suggested that a study be conducted to determine whether feedback can be used, and to what degree, to shape an individual's orientation response in the homogeneous environment. (Author)
