生物的类别特异性缺陷被不同地解释为由于不同类别中概念熟悉度的差异而造成的人工制品（E。Funnell & J.谢里丹，1992年）或作为一个潜在的损害感官知识的结果（E。K. Warrington & T. Shallice，1984）。目前可用的刺激材料的缺点阻碍了实证检验这些假设的努力。描述了一组新的刺激，作者开发，以克服现有的集的局限性。这套照片由彩色照片组成，根据熟悉度和视觉复杂度进行分类。这个集合被用来测试一个典型病人J.B.R.的语义知识。（E. K. Warrington & T. Shallice，1984）。结果表明，J.B.R.的赤字为生活的东西不能解释在熟悉的影响，最严重的影响类别是那些识别是最依赖于感官信息。
Category-specific deficits for living things have been explained variously as an artifact due to differences in the familiarity of concepts in different categories (E. Funnell & J. Sheridan, 1992) or as the result of an underlying impairment to sensory knowledge (E. K. Warrington & T. Shallice, 1984). Efforts to test these hypotheses empirically have been hindered by the shortcomings of currently available stimulus materials. A new set of stimuli are described that the authors developed to overcome the limitations of existing sets. The set consists of color photographs, matched across categories for familiarity and visual complexity. This set was used to test the semantic knowledge of a classic patient, J.B.R. (E. K. Warrington & T. Shallice, 1984). The results suggest that J.B.R.'s deficit for living things cannot be explained in terms of familiarity effects and that the most severely affected categories are those whose identification is most dependent on sensory information.
