Retrieval from iconic memory with shape as the selection criterion

Selection of items from iconic memory on the basis of shape was studied by means of the Sperling (1960) partial report procedure. The results indicated that partial report by shape was superior to whole report, that partial report by location was superior to partial report by shape, and that the accuracy of report as a function of delay of indicator declined at the same rate for selection by shape and selection by location. The results were discussed in the framework of the flow of visual information within S.
