Attempts to measure the involvement of an active memory process in the storage of the memory stimulus and to determine if such involvement is necessary for obtaining a Posner effect, which suggest that visual memory is not damaged by distractor tasks. (Author/RK)

The nature of the target designation process--which involves forming interassociated mental structures to allow retrieval of individual items of information--was studied. It was shown that visual imagery instructions improved target identification as well as word recognition but did not appear to affect the representational format. (Author/MH)

Experiments were performed to determine the contribution of imagery and semantic factors to the hypermnesia effect (increases in retention over successive recall attempts). Results showed that hypermnesia accompanies meaningful processing regardless of whether verbal or imagery encoding is emphasized. Semantic elaboration increases reminiscence…
