Two studies by Kosslyn (1976) attempted to test this assertion. Kosslyn first tested the association strength between animals and their physical attributes. For instance, for most people “claws” are more strongly associated with “cat” than is “head,” although cats, of course, have both. Kosslyn found that when people did not use imagery, they were fasterto verify that cats had claws (high association value, small visual part of a cat) than to verify that cats had heads (low association value, large visual part of cat). Propositional theory would predict that the higher the association value, the more propositions relating the tow items and thus the faster the verification time (Finke, 1989).
