Sequences containing 10 numbers from 1-20 were presented in serial-order or random-order at rates of 1/sec, 2/sec, and 4/sec for serial-order or same-orderrecall by eight Ss. Stimulus duration was constant, so that the interpresentation interval decreased as rate of presentation increased. Serial-order recall was greater for serial-order presentation than for random-order presentation. The decrease in recall as presentation rate increased was similar for both serial-order and random-order presentation. This result indicates that serial-order recall of random-order presentation does not involve reordering or repeated sequential scanning. It is consistent with the view that serial-order recall of serial-order presentation is greater because identification time is decreased. due to the decrease in the range of relevant alternatives, so that increased encoding time results in storage of more information.
