Attention and Attendabilia: The Perception of Attentional Affordances

Abstract

Agents are continually faced with two related selection problems: i) the problem of selecting what to do from a space of possible behaviours; ii) the problem of selecting what to attend to from a space of possible attendabilia. We have psychological mechanisms that enable us to solve both types of problem. But do these mechanisms follow different principles or work along the same lines? I argue for the latter. I start from the theory that bodily action is supported by a sensitivity to affordances. Strong evidence suggests that affordances feature in our perception of the world and that affordance perception can trigger the neural preparation of the afforded act. An agent can thus see a teapot as grippable and their doing so can automatically ready a gripping response. Something affords attending for an agent just in case it is a possible target of their focal attention. I argue that we are sensitive to these attentional affordances in much the same way. First I argue that we perceive things as attendable. Second I argue that our doing so can trigger the preparation of shifts in focal attention. My case for this is based on a variety of phenomenological, neurological and behavioural parallels between our sensitivity to bodily affordances and our sensitivity to attentional affordances. This yields a unified account with specific implications for our understanding of attention and affordance perception and general implications for our understanding of how the mind solves selection problems.
