DISSOCIATIVE EFFECTS OF GENERATION ON ITEM AND ORDER RETENTION

The effects of generation on the long-term retention of item and order information were examined in a between-list design in 3 experiments. In each experiment, completing word fragments during presentation significantly impaired long-term retention of serial order, as measured by either a reconstruction task or the amount of input-output correspondence in free recall. Memory for the individual items, however, was sometimes helped by generation. This pattern of dissociation, reminiscent of immediate memory findings, is used to interpret problematic issues in the generation effect literature and to argue for the role of the item-order distinction in the long-term-memory arena.
