This chapter presents the coordinate-system orientation representation (COR) hypothesis. It lays out the assumptions of the COR and then discusses the various forms of orientation errors that could arise in constructing or using the posited representations. The hypothesis provides something that has been lacking in cognitive research on orientation: a conceptual framework for thinking about how the orientation of objects might be represented. It also calls attention to nonobvious differences among forms of orientation error (e.g., tilt-direction errors, reflections across object axes, reflections across external axes) and suggests underlying causes for each error type. Most notably, the hypothesis provides specific interpretations for the various forms of mirror-reflection error.

Keywords: visual perception; visual location; orientation perception; coordinate-system orientation representation hypothesis; mirror-reflection error
