title: Constrained formation of object representations.
abstract: Viewers were presented with a rapid sequence of very brief stimulus pairs, each of which consisted of a pictured object followed by a related or unrelated word. The form of relatedness between the picture and word was manipulated across experiments (identical concept, associated concept, ink color of the picture). Recognition memory for the pictures was affected not only by whether or not paired items were conceptually identical or semantically related, but also by whether or not the words named an irrelevant feature, ink color. These results show that sequential items are integrated on the basis of similarity at whatever level is available, so that the stability of the memory representation of one or both items is increased. We propose that a common mechanism may underlie integration, priming, and selective attention.
