Abstract
Human Ss performed a card-sorting task and were asked afterward to report the number of responses they had made in a sequence. Ability to give the correct number was found to vary as a function of the size of the number and as a function of the dissimilarity of the sequence-ending card. Ss who did not count the sequence length overestimated the length. The results are discussed in terms of the concept of number as a stimulus in psychophysical investigation.
