This paper connects ideas from twentieth century Gestalt psychology, experiments in vision science, and Maurice Merleau-Ponty’s phenomenology of perception. I propose that when we engage in simple sensorimotor tasks whose successful completion is open, our behavior may be motivated by practical perceptual awareness alone, responding to invariant features of the perceptual field that are invisible to other forms of perceptual awareness. On this view, we see more than we think we see, as evidenced by our skillful bodily behavior.

The smooth integration of the natural sciences with everyday lived experience is an important ambition of radical embodied cognitive science. In this paper we start from Koffka’s recommendation in his Principles of Gestalt Psychology that to realize this ambition psychology should be a “science of molar behaviour”. Molar behavior refers to the purposeful behaviour of the whole organism directed at an environment that is meaningfully structured for the animal. Koffka made a sharp distinction between the “behavioural environment” and the “geographical (...) environment”. We show how this distinction picks out the difference between the environment as perceived by an individual organism, and the shared publicly available environment. The ecological psychologist James Gibson was later critical of Koffka for inserting a private phenomenal reality in between animals and the shared environment. Gibson tried to make do with just the concept of affordances in his explanation of molar behaviour. We argue however that psychology as a science of molar behaviour will need to make appeal both to the concepts of shared publicly available affordances, and of the multiplicity of relevant affordances that invite an individual to act. A version of Koffka’s distinction between the two environments remains alive today in a distinction we have made between the field and landscape of affordances. Having distinguished the two environments, we go on to provide an account of how the two environments are related. Koffka suggested that the behavioural environment forms out of the causal interaction of the individual with a pre-existing, ready-made geographical environment. We argue that such an account of the relation between the two environments fails to do justice to the complex entanglement of the social with the material aspects of the geographical environment. To better account for this sociomaterial reality of the geographical environment, we propose a process-perspective on our distinction between the landscape and field of affordances. While the two environments can be conceptually distinguished, we argue they should also be viewed as standing in a relation of reciprocal and mutual dependence. (shrink)
