LR has extensive bilateral pathology to prefrontal cortices after head injury and marked changes to interpersonal and social behavior relative to his premorbid state. WAIS scores revealed intact IQ at superior levels, equivalent to premorbid ability as measured by the NART. LR performed at normal levels on a battery of executive function tasks, as did eight age- and IQ-matched controls. However, he showed impaired implicit learning on a serial reaction time task, and performed differently from controls on a mere exposure effect task. This case supports claims that implicit cognition may underpin some aspects of normal social functioning.
LR在头部受伤后双侧前额叶皮质出现广泛病变,与病前状态相比,其人际和社会行为发生了显著变化。韦氏成人智力量表(WAIS)得分显示其智商处于较高水平且完好无损,与通过国家成人阅读测验(NART)测得的病前能力相当。LR在一系列执行功能任务中的表现与八名年龄和智商匹配的对照组一样,处于正常水平。然而,他在序列反应时任务中表现出内隐学习受损,并且在单纯曝光效应任务中的表现与对照组不同。该病例支持了内隐认知可能是正常社会功能某些方面基础的观点。
