Dispositional Properties

Ever since Gibson proposed the concept of ‘affordances’ in 1979, we have been arguing about the best way to formalize the idea in a way that can allow us to successfully explain behavior. The first approach was to consider them as dispositional properties of task environment which can support skillful perception and action. A more recent approach considers them more broadly as relations between properties of organisms and their environments. This expands the spatial and temporal scope of affordances; we stand in many kinds of relations to our physical but also social and cultural environments. Relational affordances are therefore offered as an ecological way to explain behaviors in these domains. However, these relational affordances do not, as a rule, interact with perceptual media and therefore do not create perceptual information about themselves. This means they cannot be perceived, which in turn means they cannot play any role in an ecological explanation of a behavior. This paper briefly reviews the dispositional vs relational accounts of affordances, explains the problem, and proposes an information-based alternative (building on Golonka, 2015). Affordances are not relational, but fortunately information is, and this is where we should focus our attention.

Radical Ideas

In 1979, James Gibson completed his third and final book “The Ecological Approach to Visual Perception”. That book can be seen as the synthesis of the many radical ideas he proposed over the previous 30 years – the concept of information and its sufficiency, the necessary link between perception and action, the need to see perception in relation to an animal's particular ecological niche and the meanings (affordances) offered by the visual world. One of the fundamental concepts that lies beyond all of Gibson's thinking is that of optic flow: the constantly changing patterns of light that reach our eyes and the information it provides. My purpose in writing this paper has been to evaluate the legacy of Gibson's conceptual ideas and to consider how his ideas have influenced and changed the way we study perception.

Negative Aftereffect

Optic flow is known to adapt the direction of walking, but the locus of adaptation remains unknown. The effect could be due to realignment of anatomical eye, head, trunk, and leg coordinate frames or to recalibration of a functional mapping from the visual direction of the target to the direction of locomotion. We tested whether adaptation of walking to a target, with optic flow displaced by 10°, transfers to facing, throwing, and kicking a ball to the target. A negative aftereffect for initial walking direction failed to transfer to head orientation or throwing or kicking direction. Thus, participants effectively threw or kicked the ball to the target, and then walked in another direction to retrieve it. These findings are consistent with recalibration of a task-specific visuo-locomotor mapping, revealing a functional level of organization in perception and action.
