Although imagery is traditionally thought to be inherently linked to visual perception, growing
evidence shows that mental images can arise also from nonvisual modalities. Paradigmatic …

Although it is generally assumed that vision is orientation invariant, that is, that shapes can
be recognized regardless of viewing angle, there is little evidence that speaks directly to this …

An object viewed from different angles can be recognized and distinguished from similar
distractors after the viewer has had experience watching it rotate. It has been assumed that …

We tested shape constancy from novel views in the case of binocular viewing, using a
variety of stimuli, including polyhedra, polygonal lines, and points in 3-D. The results of the …

Learning invariances allows us to generalise. In the visual modality, invariant
representations allow us to recognise objects despite translations or rotations in physical …

We describe experiments with a versatile pictorial prototype-based learning scheme for 3-D
object recognition. The Generalized Radial Basis Function (GRBF) scheme seems to be …

In performing recognition, the visual system shows a remarkable capacity to distinguish
between significant and immaterial image changes, to learn from examples to recognize …

Five experiments are reported in which the time to verify the name of different three-
dimensional common objects shown rotated in depth was investigated. Views of computer …

We report results from an experiment showing that a tall pillar with a triangular base evokes
radically different three-dimensional (3D) percepts depending on the vantage point from …

In four experiments, we examined whether generalization to unfamiliar views was better
under stereo viewing or under nonstereo viewing across different tasks and stimuli. In the …
