ABSTRACT
An affordance is an opportunity for action provided by the environment to an organism. Affordances can often be defined as an environmental property scaled by the action capabilities of an organism. For example, an opening affords passing through for an individual whose widest body dimension (usually the shoulder, S) is less than the dimensions of the aperture (A). However, not all affordances are relative to individuals. It is often the case that people act together to achieve a shared goal. While considerable attention has been given to how affordances constrain individuals, only recently have a few investigations investigated the affordances of groups of individuals engaged in a joint action. For example, Isenhower and colleagues (2005) demonstrated that people are able to distinguish the boundaries between an affordance for oneself and an affordance for a dyad. The present study extended previous findings regarding affordances and joint actions by determining whether individuals were perceptually sensitive to affordances specific to a dyad of which they were a member.
