Document Summary
Participants were asked to compare two objects and decide if they are the same. The objects were presented at different orientations. Critically, the time to compare is related to the degree of rotation. If imagery, like perception, is spatial (i. e. , analog) then it should take longer for participants to find parts that are located further from the initial point of focus. 1) implicit encoding: images give access to information not explicitly encoded, e. g. , brooks (1968) 2) perceptual equivalence: imagery activates similar systems as does perception, e. g. , perky (1910): people are sometimes unable to distinguish between their own images and faint pictures. 4) transformational equivalence: image transformations and physical transformations are governed by the same laws of motion, recall mental rotation studies. It takes time to rotate (depends on angle of rotation) It seems continuous (i. e. , there are intermediate states) The whole object is rotated and not just the parts.
