Generation of a pictorial code.
In Experiments I and II direct measures were obtained of the time required to convert a picture or a sentence to a report of visualization or to a simple drawing, latencies were faster for pictures than for sentences and were affected by the surface form of the sentence. In Experiment Ill, Ss matched pictures or sentences against a test picture under conditions of simultaneous or successive presentation. "Yes" and "No" response times were affected by sentence form under both conditions, although the difference between sentence-picture and picture-picture comparisons was virtually eliminated under the successive condition. In Experiment IV, Ss held a sentence or picture in memory over a 1,500-msec interval at the end of which a test picture or an instruction to draw the design was presented. Construction latencies were shorter in response to pictures than sentences, and there were effects of sentence form on verification time. Some implications of these results are discussed.
