Abstract: We developed a new direct priming task, which is constructed by 3 syllable Japanese Kana letters and contains high familiarity words and low familiarity words according to Chihara. We performed this task to the normal controls(C group), the patients with alcoholics (AL group), global amnesic patients with various origins (AM group) and the patients with alcohol Korsakoff syndrome(K group). Each group was matched age, sex and educational level. Every group demonstrated the priming effects and the priming effect of low familiarity words was larger than that of high familiarity words in C group and AL group. The priming effect of high familiarity task demonstrated no statistical differences among C group, AL group, AM group and K group. However, the priming effect of low familiarity task revealed significantly smaller in K group and AM group compared with that in C group and AL group. The patients answered correctly in some of the present direct priming task without understanding the meaning of words, suggesting that other factors besides meaning of the words are related to the direct priming effects.

Memory function in cases with Heubner's recurrent artery occlusion
Hideko Mizuta (Department of Rehabilitation, Itami municipal hospital), Naoyasu Motomura (Department of Health Science, Osaka Kyoiku University)
Abstract: We reported 5 cases with Heubner's recurring artery occlusion, to whom we conducted detailed neuropsychological examinations. We performed AVLT, paired associate learning task and Benton's visual learning test as declarative memory tasks and motor and cognitive procedural memory tasks developed by Komori. Compared with age and intelligence matched normal control subjects and patients with SAH without Heubner's recurrent artery occlusion, patients with Heubner's recurring artery occlusion demonstrated the lower scores both on declarative and on motor procedural memory tasks. These results suggest that caudate nucleus may be related both with declarative memory and with procedural memory.
