Abstract

People frequently encounter and interact with objects and scenes from various vantage points in everyday life. The present set of studies explored canonical viewpoints in objects and scenes. Three themes were focused on: First, what the actual preferred views are for objects verses scenes; second, whether those preferred views lead to better encoding and/or recognition; and third, how different types of tasks affect both the canonical view for objects and scenes as well as whether training/testing at canonical views affects performance. Experiments 1-3 demonstrated that people have distinct viewing preferences, even across different tasks, for objects (oblique and more level) and scenes (straight on and more overhead vertically). Experiments 4 and 5 demonstrated that when participants encoded objects and scenes from their canonical view they were more efficient at recognizing the viewpoints from even non-canonical perspectives. Finally, Experiment 6 explored canonical views in a judgment of relative direction task and showed that unlike the recognition task, both objects and scenes showed an advantage in straight on views with no differential alignment effects, suggesting that the canonical views are task-specific.
