Reasoning about the referent of a picture versus reasoning about the picture as the referent: An effect of visual realism

Abstract

Research on picture perception and picture-based problem solving has generally considered the information that enables one to “see” and think about a picture’s subject matter. However, people often reason about a picture or representation as the referent itself. The question addressed here is whether pictorial features themselves help determine when one reasons about the referent of an image, as with an engrossing movie, and when one reasons about the image in its own right, as with abstract art. Two experiments tested the hypothesis that pictures with relatively high fidelity to their referents lead people to think about those referents, whereas pictures with relatively low fidelity lead people to think about the picture as a referent. Subjects determined whether marks on the bottom and top boards of an open hinge would meet if the hinge were closed. Accuracy and latency results indicated that subjects who saw realistic displays simulated the physical behavior of the hinge through analog imagery. In contrast, subjects who saw schematic displays tended to reason about static features of the display such as line lengths and angles. The results demonstrate that researchers must be cautious when generalizing from reasoning about diagrammatic materials to reasoning about the referents themselves.
