Unilateral temporal lobectomy patients and normal control subjects were tested in a speeded naming task with pictures of living and nonliving things that were equated for name frequency, familiarity, and visual complexity. Although right temporal lobectomy patients and normal subjects performed equally well with the living relative to nonliving things, left temporal lobectomy patients were disproportionately impaired at naming nonliving things. This result has several implications: First, it supports the existence of category-specific naming impairments. In particular, it undermines the proposal that living-nonliving dissociations are artifactual, resulting from the greater difficulty of living things. Second, it demonstrates an asymmetry in the neural representation of nonliving things, in favor of the left hemisphere. Third, it casts doubt on the hypothesis that the anterior temporal cortices are convergence zones that are particularly necessary for the naming of living things.
对单侧颞叶切除术患者和正常对照受试者进行了一项快速命名任务测试，使用的是具有相同名称频率、熟悉度和视觉复杂性的生物和非生物图片。尽管右颞叶切除术患者和正常受试者在命名生物相对于非生物方面表现同样出色，但左颞叶切除术患者在命名非生物时受到的损害不成比例。这一结果有几个含义：第一，它支持了特定类别命名障碍的存在。特别是，它削弱了一种观点，即生物与非生物的分离是人为造成的，是由于生物更难命名所致。第二，它证明了非生物在神经表征上的不对称性，有利于左半球。第三，它对前颞叶皮质是生物命名特别必要的汇聚区这一假设提出了质疑。
