Six pigeons were trained to reproduce two‐event sequences in an experiment that employed a discrete‐trial procedure that required subjects to peck one of four possible sample sequences (left‐left, left‐right, right‐right, right‐left) signaled on a given trial by the successive illumination of response keys. Following a retention interval (0.1 to 30 seconds), a reinforcer was delivered if a subject reproduced the prior sample sequence during a test condition in which both left and right keys were illuminated. The pigeons readily reproduced the orders in which they had just seen and pecked two illuminated keys. Reproduction accuracy declined as the retention interval was increased. Homogeneous sequences (left‐left, right‐right) were reproduced with greater accuracy than heterogeneous sequences.
