混淆左半球的言语化策略可以被认为是一个主要的问题，在评估的假设参与右颞叶边缘结构的“非言语”的视觉/图形记忆处理。我们通过对60例左颞叶癫痫（LTLE）或右颞叶癫痫（RTLE）患者和30例健康对照者进行易于语言表达的Benton视觉保持测试来解决这个问题。我们正式估计了每个项目的信息（口头）内容，假设需要单独保留口头记忆中的项目。结果表明，只有在右颞叶功能障碍的存在下，语言学习和图形记忆的混淆。当图形材料的言语负荷超过其言语学习能力时，RTLE患者的选择性视觉/图形学习缺陷变得明显。而不是排除使用抽象的图形项目的言语化，它的列入提供了一种可能性，以控制补偿策略，掩盖存在的视觉/图形记忆缺陷。
Confounding left hemisphere verbalization strategies can be suggested as being a major problem in the evaluation of the assumed involvement of right temporo-limbic structures in ''nonverbal'' visual/figural memory processing. We addressed this issue by evaluating the easily-verbalized Benton-visual-retention-test in 60 patients with either left (LTLE) or right temporal lobe epilepsy (RTLE) and 30 healthy controls. We formally estimated the informational (verbal) content of each item which hypothetically would be needed to solely retain the item from verbal memory. The results indicated confounding of verbal learning and figural memory only in the presence of right temporal lobe dysfunctions. Selective visual/figural learning deficits in RTLE patients became obvious when the verbal load of the figural material exceeded their verbal learning capacity. Instead of excluding verbalization by the use of abstract figural items, its inclusion provides a possibility to control compensatory strategies which overshadow the presence of visual/figural memory deficits.
