Opportunities for action.
The environment offers “ability” of actions – the ball has catch-ability, the gap has jump-ability, the space has run-ability. Affordances are dynamic; they can change over short and long time scales based on changes in the environment and changes in ones ability.
Information in the environment is directly perceived, which contains affordances (opportunities for action). Information specifies affordances, those properties of the environment whose perceived meaning is the actions they both allow and invite and organism to perform (Araujo, D., & Davids, K., 2011).
