注意力是感知和认知能力的基础，是认知神经科学研究的中心问题。提高主动调控注意力的能力在脑疾病治疗和高压力高节奏工作特殊人群培训等诸多领域有迫切需求。探索人的触觉感知与交互行为对注意力的影响机制，将深化对于大脑神经活动规律的认识。.我们前期研究发现，基于触觉反馈的力控制任务可以有效提高短期注意力，但其它类型的触觉交互任务是否有效尚不清楚，此外导致注意力提高的生理机制有待揭示。据此，本项目将触觉与神经科学相结合，拟采用神经电生理和神经影像学等方法，系统研究基于触觉通道的感知任务、控制任务和左右脑分工机制三方面的注意力调控机理，重点探究多指力协调控制、左右脑协调、胼胝体激活强度等因素对注意力调控的影响，探索以触觉为核心的多感觉交互任务对注意力的可塑性，揭示注意力调控的神经机制。针对儿童注意缺陷障碍和多动症治疗开展调控效果的验证。研究成果将为探索注意力训练的新技术和新方法提供科学依据。

As the central problem of cognitive neuroscience field, attention is the foundation of human’s perception and cognitive ability. Improving the ability of actively modulating attention is urgent and necessary in many areas such as mental disorder treatment and training of professionals with heavy pressure and heavy workload in special areas. Exploring the interaction mechanism between haptic perception/interaction and attention may drive the understanding on the mechanism of brain neural activities. .In our previous study, we found that force control tasks with pure haptic feedback promoted short-term focused attention. However, the effectiveness of other haptic interaction tasks remains unclear. In addition, the physiological mechanism of promoting attention is yet to be revealed. This project combines haptics with neuroscience, and employs the methods of neuroelectrophysiology and neuroimaging, and studies systematically attention modulating mechanism of haptic perception tasks, haptic control tasks and coordination of left and right brain hemispheres, and explores several factors’ effect on attention modulating such as synergetic control of multiple fingers, coordinated control of two hemispheres and activated intensity of callosum. Furthermore, we plan to observe the plasticity of attention by conducting haptic-centered multisensory interact tasks, and thus to reveal the neural mechanism of regulating attention through haptic channel. Finally, we will validate the transferability of the effect of attention regulation on children with ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder). The research findings may provide evidences for exploring new technology and new methods of attention training.
