摘要:

  暗示性运动是指个体观看静止图片时从中知觉到的运动.研究者采用高低认知水平两类暗示性运动刺激材料,借助“冻结帧”、直接观看、运动后效和fMRI适应等任务范式,探讨了注意和意识在暗示性运动加工中的作用及其记忆特点;并借助脑成像等技术,考察了颞中区、颞上皮层区、颞上沟、镜像神经元系统等脑区在暗示性运动加工中的作用.但由于暗示性运动加工涉及“视觉腹侧通路与背侧通路功能的分离与整合”问题,目前对相关研究结果和解释还存在争议,暗示性运动加工的认知神经机制仍有待于进一步研究.Implied motion is defined as extraction of motion information from a stationary photo. With low-level and high-lever stimuli, researchers usually employ four paradigms (i.e., freeze-frame, passively viewing, motion aftereffect, and fMRI adaption) to investigate implied motion. The role of attention and awareness in implied motion and the memory representation of implied motion are key issues in previous studies. Researchers also focus on the various activated brain regions engaged in implied motion, including medial temporal cortical areas (MT/MST), superior temporal sulcus, and mirrorneuron system. Future studies are needed to further explore the cognitive and neural mechanisms of implied motion in order to clarify whether motion and form processing in human visual system, especially the neural network for motion from form, are dissociated or integrated.
