项目摘要

The senses interact and complement each other to provide reliable sensory information about the external and internal world. The main objectives of my research program are (1) to determine how visual, auditory and vestibular information are combined to provide reliable cues to body orientation; experiments will involve novel investigations into the contributions of extremely peripheral vision on orientation and self-motion perception while sitting and standing; (2) to determine the coding and flexibility of body representation and its effects on sensory processing; experiments will involve psychophysical measures of perceived body size and the location of touch and how these perceptions can be altered by experience; and (3) to determine the contribution of sensory input to the sense of body ownership; we have developed the first quantitative estimate of the perception of body ownership; experiments will include disrupting the grounding influence of the vestibular system and creating artificial links between visual and tactile cues to enhance the projection of the self into video images. The common element to these three themes is to quantify the emerging central role of the body in many aspects of perception.******To whom the research is important: Scientifically, understanding how body representation contributes to our sense of orientation, the perceived location of stimuli, and our perception of our selves, will alter our understanding of how sensory processing gives rise to perception. Practical applications include incorporating multisensory feedback into human factors design to provide better orientation cues, especially in the presence of degraded sensory input such as in space, or underwater. Understanding how the perception of self can be manipulated can be used for improved virtual reality experience in real gaming.******Anticipated outcomes: We expect to show that the far periphery of the visual field is important in our perception of orientation and self-motion; that body perception is plastic and that changes affect tactile processing of intensity and location; and that the vestibular system plays an important role in grounding the self that can be measured and that is subject to disruption. ******Benefits to the research field and Canada: These studies will transform basic perceptual research by quantifying the unexpected role of the body in multiple aspects of perception. They will inform applications that may help people maintain orientation in unusual environments. The exceptional training opportunities offered by my lab and associated training grants will help create the Canadian scientists of tomorrow. ********
感官相互作用并相互补充,提供有关外部和内部世界的可靠感官信息。我的研究计划的主要目标是(1)确定如何将视觉、听觉和前庭信息结合起来,为身体方向提供可靠的线索;实验将涉及对极周边视觉对坐着和站立时的定向和自我运动感知的贡献的新颖研究; (2) 确定身体表征的编码和灵活性及其对感觉处理的影响;实验将涉及对感知身体尺寸和触摸位置的心理物理学测量,以及如何通过经验改变这些感知; (3) 确定感觉输入对身体所有权感的贡献;我们对身体所有权的认知进行了第一个定量评估;实验将包括破坏前庭系统的基础影响,并在视觉和触觉线索之间建立人工联系,以增强自我在视频图像中的投射。这三个主题的共同点是量化身体在感知的许多方面中新兴的核心作用。******这项研究对谁来说很重要:从科学角度讲,了解身体表征如何影响我们的方向感、感知刺激的位置以及我们对自我的感知,将改变我们对感觉处理如何产生感知的理解。实际应用包括将多感官反馈纳入人因设计中,以提供更好的方向提示,特别是在感官输入退化的情况下,例如在太空或水下。了解如何操纵自我感知可用于改善真实游戏中的虚拟现实体验。******预期结果:我们希望表明视野的远缘对于我们对方向和自我运动的感知非常重要;身体感知是可塑的,变化会影响强度和位置的触觉处理;前庭系统在使可测量且易受干扰的自我扎根方面发挥着重要作用。 ******对研究领域和加拿大的好处:这些研究将通过量化身体在感知的多个方面的意想不到的作用来改变基础感知研究。它们将通知可帮助人们在异常环境中保持方向的应用程序。我的实验室提供的特殊培训机会和相关培训补助金将有助于培养未来的加拿大科学家。 ******
