根据皮质组织的模块模型，纹状体外皮层的许多区域专门用于物体类别。这些模型通常假定存在一个用于检测类别归属的早期处理阶段。功能成像能否分离出负责检测某一类别的成员（如面部或字母）的区域呢？我们考虑三个不同区域（两个对面部有选择性，一个对字母有选择性）的反应是否支持类别检测。这些区域的活动对同一类别中一个示例的重复呈现比对同一类别不同示例的呈现更容易产生习惯化，但仅针对该区域有选择性的类别。因此，这些区域似乎起着比检测更复杂的计算作用，是在个体层面处理刺激。根据先前的研究，我们认为面部选择性区域可能参与个体层面的面部感知，而字母选择性区域可能会对字体信息进行调整，以便更高效地识别字母。
According to modular models of cortical organization, many areas of the extrastriate cortex are dedicated to object categories. These models often assume an early processing stage for the detection of category membership. Can functional imaging isolate areas responsible for detection of members of a category, such as faces or letters? We consider whether responses in three different areas (two selective for faces and one selective for letters) support category detection. Activity in these areas habituates to the repeated presentation of one exemplar more than to the presentation of different exemplars of the same category, but only for the category for which the area is selective. Thus, these areas appear to plap computational roles more complex than detection, processing stimuli at the individual level. Drawing from prior work, we suggest that face-selective areas may be involved in the perception of faces at the individual level, whereas letter-selective regions may be tuning themselves to font information in order to recognize letters more efficiently.
