Abstract:
OBJECTIVES: In this study, the cognitive characteristics, especially priming effect, of above 50 years old age group who had less than 25 points in K-MMSE were investigated. METHODS: In this study, an implicit memory test measuring priming effect was made and adminis-tered to old age people who had less than 25 points in K-MMSE in screening session. To control the effect of age, educational level and intelligence, demographic variables were measured, and the subtests of KWIS, vocabulary and block design were administered. Descriptive statistical analysis of the two priming measures and correlational analysis between variables were done. To test the effect of cognitive functioning on priming effect multiple regression analysis was done. RESULTS: Correlational analysis revealed priming score obtained from correct identification response was positively correlated with K-MMSE and ADAS-Cog. And priming score obtained from mean reaction time was positively correlated with age and negatively correlated with vocabulary substest of KWIS. The regression analysis results indicated general cognitive functioning measured by ADAS-Cog has significant effect on priming score obtained from correct identification response, whereas age has significant effect on priming score obtained from mean reaction time. CONCLUSIONS: The results revealed that as cognitive deterioration progresses priming effect which identify primed stimulus correctly diminish, and as one grow older within age 50 to 70, priming effect which identifies primed stimulus quickly increase.
