title: Topology and mental processes.
abstract: The study reported here considers the effect of rotation on the decision time taken to compare nonrigid objects, presented as like and unlike pairs of knots and unknots. The results for 48 subjects, 21 to 45 years old, support the notion that images which have a characteristic 'foundation part' are more easily stored and accessed in the brain. Also, there is evidence that the comparison of deformable objects is processed by mental strategies other than self-evident mental rotation.
