Findings of category-specific impairments have suggested that human semantic memory may be organized around a living/nonliving dichotomy. In order to assess implicit memory performance for living and nonliving concepts, one group of neurologically intact individuals participated in a cross-form conceptual priming paradigm. In Block 1, pictures primed words while in Block 2 words were used to prime pictures. Across all phases of the experiment, subjects decided whether items represented something which was living or nonliving, and response times were recorded. Results revealed greater priming for living concepts across both blocks. Greater priming for living concepts may have occurred because of increased or prolonged conceptual activation of these concepts. Results are discussed in the context of theoretical accounts of the category-specific impairments observed in brain-damaged populations.
特定类别损伤的研究结果表明，人类语义记忆可能围绕有生命/无生命的二分法进行组织。为了评估对有生命和无生命概念的内隐记忆表现，一组神经功能正常的个体参与了一种跨形式概念启动范式。在第1组中，图片启动单词，而在第2组中，单词用于启动图片。在实验的所有阶段，受试者要判断项目是否代表有生命或无生命的事物，并记录反应时间。结果显示，在两个组中对有生命概念的启动作用更大。对有生命概念的启动作用更大可能是因为这些概念的概念激活增加或延长。本文将结合在脑损伤人群中观察到的特定类别损伤的理论解释来讨论这些结果。
