The Theory of Affordances
James J. Gibson originally introduced the term “affordance” in his 1977 article ‘The Theory of Affordances’, which he subsequently elaborated his book The Ecological Approach to Visual Perception in 1979. Gibson defined affordances as all “action possibilities” latent in the environment, objectively measurable and independent of the individual’s ability to recognize them, but always in relation to agents and therefore dependent on their capabilities. For instance, a set of steps which rises four feet high does not afford the act of climbing if the actor is a crawling infant.
An affordance is a relation between an object or an environment and an organism, that affords the opportunity for that organism to perform an action. For example, a knob affords twisting, and perhaps pushing, while a cord affords pulling. As a relation, an affordance exhibits the possibility of some action, and is not a property of either an organism or its environment alone.
