右侧脑发育不全遗忘症患者的启动效应与右侧皮层的分离

AN AMNESIC PATIENT WITH RIGHT CEREBRAL DYSPLASIA:PRIMING INDEPENDENT OF RIGHT NEOCORTEX

采用ＷＭＳ－ＣＲ、ＷＩＳＣ－ＣＲ和４项内隐记忆任务（偏好、自由联想、字根补笔和字辨认）观察一例右侧大脑发育不全患者和两组正常对照的知觉性启动效应和语义性启动效应。发现该患者智力发育迟滞、记忆功能严重障碍，但两种启动效应正常。显示右侧大脑皮层发育不全不影响两种启动效应任务操作，启动效应与右侧大脑皮层分离。不支持Ｋｅａｎｅ等人认为知觉性启动效应的神经学基础在大脑皮层的结论。结合先的研究结果认为知觉性启动效应可能与基底神经节有关，语义性启动效应可能与左侧大脑皮层有关。

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.
