根据认知科学和脑科学的描述，身体表征和视觉空间表征都是在发育过程中逐渐获得的。一个典型的例子是神经元（位于腹侧顶叶内区）的面部表征，它的功能不仅是编码视觉刺激在以头部为中心的参照系中的位置，而且还将视觉感觉与触觉感觉联系起来。本文提出了一个使机器人能够获得这种表示的模型。通过“手视行为”（hand regard behavior），即机器人将手移到脸前，利用手臂姿势的本体感觉作为参考数据，应用自组织地图（SOM）和Hebbian学习方法。给出了仿真结果，并对现有模型的局限性和未来需要解决的问题进行了讨论。
Both body and visuo-spatial representations are supposed to be gradually acquired during the developmental process as described in cognitive and brain sciences. A typical example is face representation in a neuron (found in the ventral intraparietal (VIP) area) of which the function is not only to code for the location of visual stimuli in the head-centered reference frame, but also to connect visual sensation with tactile sensation. This paper presents a model that enables a robot to acquire such representation. The proprioception of arm posture is utilized as reference data through the "hand regard behavior," that is, the robot moves its hand in front of its face, and the self-organizing map (SOM) and Hebbian learning methods are applied. The simulation results are shown and discussions on the limitation of the current model and future issues are given.
