The opportunity an object presents for action is known as an ‘affordance’. A basic assumption in previous research is that images of objects, which do not afford physical action, elicit effects on attention and behavior comparable to that of real-world tangible objects. Using a flanker task, we compared interference effects between real graspable objects versus matched two-dimensional (2D) or three-dimensional (3D) images of the items. Compared to both 2D and 3D images, real objects slowed response times overall and elicited greater flanker interference effects. When the real objects were positioned out of reach, or behind a transparent barrier, the pattern of RTs and interference effects was comparable to 2D images. Graspable objects exert a more powerful influence on attention and manual responses than images due to the affordances they offer for manual interaction. These results raise questions about whether images are suitable proxies for real objects in psychological research.
