Ladan Shams, University of California at Los AngelesAaron Seitz, University of California at RiversideCOLLABORATIVE RESEARCH: MULTISENSORY PERCEPTUAL LEARNINGABSTRACTIn daily life, we frequently experience correlated sensations across our different sensory modalities. For example, as we climb up the stairs, we receive sensations to our auditory, visual, tactile, and vestibular systems that are all related to the experience of stair-climbing. These types of multisensory experiences are a key aspect of how we interact with, and learn about, the world around us. Through our experience with the world, our sensory abilities undergo refinements that allow us to optimize our performance in the tasks that we perform. These sensory refinements involve fine-tuning of processing in each of our sensory modalities, but equally importantly, in how we merge information across modalities. While much research has focused on how learning can take place within each individual sensory system, the learning of how information is combined across the senses has been largely neglected. The PIs will conduct a series of experiments in which they can track visual, auditory, and auditory-visual multisensory learning in parallel, and discriminate among different theories of multisensory processing and learning. Behavioral and neuroimaging methods will be combined to shed light on the roles that different brain areas, and the interactions between brain areas, play in the process of multisensory learning. Altogether these studies will provide fundamental insights into how our sensory systems work together and refine their interactions to best operate in the tasks that we perform.This project will be the first systematic investigation of multisensory perceptual learning. It will also be the first study of changes in interaction between brain areas that may occur as a result of sensory learning. Altogether, this study promises to provide foundational knowledge regarding the brain mechanisms involved in multisensory learning as well as the mechanisms of learning in general. Understanding multisensory learning can contribute to the development of more effective strategies for learning. These strategies can be utilized to enhance learning for typically-developed children and adults, as well as to facilitate learning and communication for individuals with deprivation in one sense (e.g., individuals with low-vision or low-hearing, patients with cochlear implants or undergoing macular degeneration or cataract surgeries). They can also contribute to devising remedial programs for dyslexia, which appears to involve deficits in combining information across the senses.

拉丹·沙姆斯，加州大学洛杉矶分校，亚伦·塞茨，加州大学河滨分校合作研究：多感官知觉学习抽象在日常生活中，我们经常在不同的感官模式中体验到相关的感觉。例如，当我们爬上楼梯时，我们接收到听觉、视觉、触觉和前庭系统的感觉，这些感觉都与爬楼梯的经历有关。这些类型的多感官体验是我们如何与周围世界互动和学习的关键方面。通过我们与世界的经验，我们的感官能力得到了改进，使我们能够在我们执行的任务中优化我们的表现。这些感官的改进涉及到我们每一种感觉模式的处理过程的微调，但同样重要的是，我们如何跨模式合并信息。虽然许多研究都集中在学习如何在每个单独的感觉系统中发生，但对信息如何在各个感官之间组合的学习在很大程度上被忽视了。pi将进行一系列实验，在这些实验中，他们可以并行跟踪视觉、听觉和听觉-视觉多感官学习，并区分不同的多感官处理和学习理论。行为和神经成像方法将结合起来，阐明不同大脑区域的作用，以及大脑区域之间的相互作用，在多感觉学习过程中发挥作用。总的来说，这些研究将为我们的感官系统如何协同工作和改进它们的相互作用提供基本的见解，以最好地在我们执行的任务中运作。这个项目将是对多感官知觉学习的第一个系统研究。它也将是第一个研究大脑区域之间相互作用变化的研究，这种变化可能是感官学习的结果。总之，这项研究有望为涉及多感觉学习的大脑机制以及一般学习机制提供基础知识。了解多感官学习有助于开发更有效的学习策略。这些策略可用于提高发育正常的儿童和成人的学习能力，以及促进在某种意义上被剥夺的个体（例如，视力低下或听力低下的个体，人工耳蜗植入或接受黄斑变性或白内障手术的患者）的学习和交流。它们还有助于设计针对阅读障碍的补救方案，阅读障碍似乎涉及到跨感官信息组合的缺陷。
