Abstract

Observations on the structure of the visual field and its central representation lead to a paradox. A functional dissociation is indicated in oculomotor or attentional control when different response modes are observed as a function of stimulus eccentricity. Alternatively, constancy of brightness throughout the visual field suggests its homogeneity. This paradox can be resolved, if perceptual and motor processes are not conceived of being controlled by separate neuronal mechanisms, but are interconnected within one frame of reference. The reafference principle allows to formulate such a common frame as it integrates afferent and efferent processes. On the basis of this concept, the visual field paradox can be interpreted as not being a paradox at all, but a necessary condition for optimal information processing.
