The meaning of things seems to be perceived immediately, directly, and can even invite action (Gibson, 1979; Koffka, 1935). From the standpoint of direct perception, we believe that perception is of behaviorally meaningful aspects of the environment, meaning perception is of affordances. Affordances are possibilities for behavior that are determined by a relationship between features of the environment and abilities of an actor (Chemero, 2003; Gibson, 1979). We hypothesized that people will be able to perceive more affordances the longer they are exposed to a picture. For this study 33 undergraduate participants viewed still images depicting indoor and outdoor environments in a random order. Participants were assigned to one of four conditions corresponding to image display duration (.2 seconds, .5 seconds, 1 second, or 3 seconds). After viewing an image, participants were asked to list as many “verb – object pairs” relating to the image as possible. A one-way ANOVA on number of responses revealed a statistically significant difference between groups [F(3, 29) = 3.01, p < .05]. Post hoc tests revealed a number of differences between individual conditions. These findings suggest that affordances are specified in stimulus information, and stimulus information is perceived immediately. It seems the human perceptual system can automatically and immediately perceive affordances in the environment, and from there can consciously cognate about what opportunities were available in a visual scene given enough time.
