Capacity limits in continuous old-new recognition and in short-term implicit memory

Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results fo r such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition pri ming reflects the central capacity limit. I argue that this phenomenon inst ead reflects limits within individual perceptual processing modules.
