Visual processing of sensory signals and our semantic knowledge about our visual world are heavily intertwined. As a consequence, our knowledge about the relative contribution of visual-perceptual and semantic dimensions to our mental and neural representations of objects and thus our ability to form categories has remained piecemeal. To address this challenge, we will carry out a detailed comparison of the mental and neural representations underlying the visual processing of object images and the representation of object words. By using large-scale online crowdsourcing of human similarity judgments, computational modeling of the underlying representational dimensions, and densely-sampled functional MRI paired with encoding models of these dimensions, this project promises to reveal the precise nature of the interplay between visual-perceptual and semantic information in brain and behavior.

感官信号的视觉处理和我们对视觉世界的语义知识是紧密交织在一起的。因此，我们关于视觉感知和语义维度对我们对物体的心理和神经表征的相对贡献的知识，以及我们形成类别的能力，仍然是零零碎碎的。为了应对这一挑战，我们将对对象图像和对象词的视觉处理的心理和神经表征进行详细的比较。通过大规模的在线众包人类相似性判断，潜在表征维度的计算建模，以及密集采样的功能MRI与这些维度的编码模型配对，该项目有望揭示大脑和行为中视觉感知和语义信息之间相互作用的精确本质。
