ROLE OF IMPLICIT NAMING IN PICTORIAL ENCODING

Sequences of pictures with mean naming latencies ranging from 600 to approximately 1,000 msec were presented for 110 msec each at 1 of 5 presentation rates, ranging from 110 to 1,500 msec per picture. At a rate of presentation that would not permit naming of long latency pictures, pictures with short naming latencies should show a distinct advantage in memory performance. At rates slow enough for all pictures to be named or too fast for any to be named, the selective effect of naming latency should be eliminated. Both recognition memory (Exps I and II) and free recall (Exps III and IV) were tested in a total of 72 undergraduates. Whereas memory performance increased dramatically when the time between pictures was increased, at no rate was a significant correlation between naming latency and memory obtained. Contrary to the dual-code prediction, implicit naming apparently was not responsible for the improvement in picture memory at slower rates.
