Symmetry and asymmetry of human spatial memory
Article Abstract:
General principles of human memory and judgment are the basis for asymmetries in proximity judgments, according to research looking at whether remembered distances satisfy the metric axiom of symmetry. These principles are that there are differences between stimuli in the contexts they create in working memory and that magnitude estimates are determined by the context in which they are made. It has been established that asymmetries appear in distance estimations. These asymmetries are limited mainly to landmarks and neighbouring nonlandmarks.

Viewpoint dependence in scene recognition
Article Abstract:
Research suggests the encoding of interobject spatial relations is viewpoint-dependent and normalization to a similar representation in memory is needed to allow novel view recognition. Numerous representations of a space are produced by numerous views of that space. Configurations of object parts may not be distinguished from configurations of objects so that the brain can seek to maintain the world's spatial structure. The research conclusions echo those being found in studies of visual object recognition.

To what extent do unique parts influence recognition across changes in viewpoint?
Article Abstract:
Research suggests that qualitative and quantitative features may be encoded by viewpoint-specific representations as an explanation of visual recognition. Experiments demonstrated that objects with a single unique part had less of a viewpoint change impact than other objects. Recognition performance grew worse as change in viewpoint grew, irrespective of the number of distinct parts. Strong viewpoint dependency was produced by additional parts.
