Recognising objects goes beyond vision, and requires models that incorporate different aspects of meaning. Most models focus on superordinate categories (e.g., animals, tools) which do not capture the richness of conceptual knowledge. We argue that object recognition must be seen as a dynamic process of transformation from low-level visual input through categorical organisation to specific conceptual representations. Cognitive models based on large normative datasets are well-suited to capture statistical regularities within and between concepts, providing both category structure and basic-level individuation. We highlight recent research showing how such models capture important properties of the ventral visual pathway. This research demonstrates that significant advances in understanding conceptual representations can be made by shifting the focus from studying superordinate categories to basic-level concepts.
识别物体不仅仅涉及视觉,还需要整合不同意义层面的模型。大多数模型关注的是上位类别(如动物、工具),而这些类别并不能捕捉概念知识的丰富性。我们认为,物体识别必须被视为一个动态过程,即从低级视觉输入通过分类组织转变为特定的概念表征。基于大型规范数据集的认知模型非常适合捕捉概念内部和之间的统计规律,提供类别结构和基本层面的个体化。我们强调最近的研究,展示了此类模型如何捕捉腹侧视觉通路的重要特性。这项研究表明,通过将重点从研究上位类别转向基本层面概念,可以在理解概念表征方面取得重大进展。
