Infants' Exploration of the Perceptual-Motor Workspace: Evidence for the Laws of Possibility and Stability
Pages 4

From a natural physical approach, the constraints on action have to be defined over the organism-environment complex: properties of the organism (its effectivities) and the environment (its information) collectively determine action possibilities. These constraints on the organism-environment synergy have been labelled affordances by Gibson (1979). By means of exploratory activities, which are dependent on the actor's possibilities to explore and on the structure of the optic array, information specifying affordances is detected. Possibilities for exploring the perceptual-motor workspace change rapidly during early development due to changes in perceptual and motor constraints.
