The effect of the length of delay interval on short-term retention was investigated in seven pigeons using delayed matching-to-sample task with three color stimuli; red, green and blue. The delay duration was changed as a function of performance accuracy by a titration method. The main results were as follows: (a) The percentage of incorrect responses did not increase as a function of delay intervals up to 4s. (b) About 70% of all incorrect responses occured on trials in which comparison stimuli were bule and green (The percentage of correct responses on these trials was about 60%). The main cause of incorrect responses in delayed matching-to-sample, and the nature of short-term information processing in pigeons were discussed.
