Imagery as an aid to retrieval for Korsakoff patients

Cortex. 1975 Jun;11(2):163-9. doi: 10.1016/s0010-9452(75)80040-2.

Abstract

Six Korsakoff patients and six alcoholic controls learned a five item P-A task under each of the following three learning conditions; Rote, Imagery, and Cued learning. Under all conditions the Korsakoff patients took more trials to learn than did the control patients. However, both imagery learning and cued learning were easier than rote learning for the Korsakoff patients when recall was used as the learning index. When a recognition measure was used instead of the recall, imagery learning proved easiest with no difference existing between cued and rote learning. In a second experiment, the patients were given the cue (a mediating link) during presentation, but not during retrieval. Under this condition the Korsakoff patients learned no more rapidly than they did by rote regardless which response measure was required. It was concluded that imagery can aid both storage and retrieval of verbal information for Korsakoff patients, while cuing aids only the retrieval process.
