Recent evidence suggests that whereas pictures are more easily recognized, discriminated, associated, and recalled than their corresponding verbal labels, this is not the case in concept acquisition/utilization tasks. If such evidence is interpreted in terms of a "frequency theory" perspective, one would expect the typically obtained frequency judgment differences between pictures and words to be reduced if "conceptual" frequency judgments are required. This expectation was confirmed in three experiments in which subjects were presented with one of two types of visual or verbal stimuli, categorized or uncategorized, with varying frequencies. Subjects for the first experiment were sixth and seventh graders. Subjects for the second and third experiment were students in a college psychology class. (Author/MKM)
