Abstract
The following operational question was investigated: do two separate, independently developed models of mental imagery tap the same underlying psychological phenomena? Empirical implications were derived from a general cognitive-information model and a bio-feedback model to be tested simultaneously within the design of a single experiment. Three measures of imagery were employed: quantity, vividness and controllability. It is shown that differential manipulation of imagery by the two types of treatments produces a predictable set of results. This demonstration of transitivity and replicability of imagery results across experimental methods and laboratories is supportive of the validity of this, now popular, psychological concept.
