On imaging and seeing: repetition priming and interactive views of imagery.

The interaction between perceptual and imaginal processes was investigated, with the use of the repetition-priming paradigm. The idea is that the overlap between processes employed in imagery and processes employed in perception will be reflected in the amount of transfer from one encounter with an item that engages perception or imagery and a second encounter that engages perception or imagery. The greater the overlap between perception and imagery, the greater the transfer between them should be. The results showed that perceptual and imaginal processes transferred maximally to themselves; that is, maximum transfer occurred when an item was processed in the same way on both encounters. Further, prior use of perceptual processes transferred to the use of imaginal processes, but not vice versa. These results are discussed as they relate to the interactive view of imagery, which holds that imagery relies on many of the same mental structures and processes as perception.
