Memory for incongruous scenes (violating "knowledge-of-the-world") versus unorganized (jumbled) arrays was tested in war veterans with unilateral penetrating missile wounds of the brain in order to assess hemispheric differences in semantic schemas in long-term memory. Left brain-damaged (LBD) patients were selectively impaired in remembering unorganized scenes compared to right brain-damage (RBD) patients. There was no significant LBD-RBD difference in remembering incongruous scenes. The results confirm the presence of hemispheric asymmetry for semantic schemas in long-term memory, even in pictorial material. However, some features in the organization of semantic schemas are common to both hemispheres and suggests presence of similar knowledge systems. The asymmetry is discussed in terms of intact left hemisphere specialization for assigning meaning to a visual scene when obvious meaning appears to be absent.
为了评估长期记忆中语义图式的半球差异，对患有单侧穿透性脑导弹伤的退伍军人进行了关于不协调场景（违反“世界知识”）与无组织（杂乱）阵列的记忆测试。与右脑损伤（RBD）患者相比，左脑损伤（LBD）患者在记忆无组织场景时存在选择性障碍。在记忆不协调场景方面，LBD患者和RBD患者没有显著差异。结果证实，即使在图像材料中，长期记忆中的语义图式也存在半球不对称性。然而，语义图式组织中的一些特征在两个半球中是共同的，这表明存在相似的知识系统。这种不对称性是根据当明显的意义似乎不存在时，完整的左半球对视觉场景赋予意义的特化来讨论的。
