Abstract: Priming is a major type of implicit memory and memory is traditionally considered as a major component of intelligence. However little is known about the relationship between priming and intelligence. This study conducted with four priming tasks, WISC-CR and WMS-CR on a patient with right cerebral dysplasia to explore the relationship between priming and intelligence. It was found that the patient performed almost equally or even bettor than two normal control groups did on the four priming tasks, but significantly impaired on WISC-CR (IQ = 56) and WMS-CR (MQ = 46). The results suggested that priming was independent of intelligence and its impairment had no effect on implicit learning. It argues that current intelligence theories ignored human unconsciousness and future intelligence tests should include priming or skill learning test contents because implicit memory is also one of the components of human abilities.
