Abstract

SS WERE INSTRUCTED TO LINK THE STIMULUS AND RESPONSE MEMBERS OF PAIRS OF NOUNS WITH EITHER VERBAL MEDIATORS (WORDS OR PHRASES) OR NONVERBAL IMAGES. THE NOUNS VARIED IN CONCRETENESS AND IMAGE-AROUSING CAPACITY ACCORDING TO INDEPENDENT RATINGS. A SIGNIFICANT (P < .01) INTERACTION EFFECT OF STIMULUS CONCRETENESS AND INSTRUCTIONAL SET ON MEDIATION LATENCY INDICATED THAT IMAGINAL MEDIATORS WERE DISCOVERED MORE QUICKLY WHEN STIMULUS TERMS WERE CONCRETE RATHER THAN ABSTRACT, BUT VERBAL MEDIATION SPEED WAS UNAFFECTED BY ABSTRACTNESS CONCRETENESS. THE FINDINGS ARE CONSISTENT WITH A HYPOTHESIS, PREVIOUSLY SUPPORTED IN PAIRED-ASSOCIATE LEARNING STUDIES, THAT VERBAL ASSOCIATIONS CAN BE MEDIATED BY NONVERBAL AS WELL AS VERBAL SYMBOLIC PROCESSES, THE AVAILABILITY AND EFFICIENCY OF EACH DEPENDING ON RELEVANT ITEM ATTRIBUTES.
