Previous studies in transitive inference using pigeons and humans following conditional discrimination training (sets of A>B, B>C, ...) showed similar tendencies in their correct response rate and/or decision time. In this experiment, university students were trained in serial learning task using five stimuli presented in sequence (A->B->C->,...) and then tested with combinations of pairs and triads. Decision time showed a symbolic distance effect. These studies indicate that humans and pigeons have functional similarity of representation of serial order.
