项目摘要
From finding an apple in the fridge to noticing a traffic signal change to red, how we pay attention to the world around us is vital to everyday life. Studied from a cognitive neuroscience perspective, research on attention has long focused on describing the basic systems we have in our brains for selecting and prioritizing what sensory information to channel to our higher-level, capacity-limited processing resources in cortex. Towards advancing our understanding in this regard, the goal of my proposal is to explore how our attentional engagement with the external world naturally ebbs and flows over time, and what factors contribute to individual variability in these attentional dynamics. My proposal has three complimentary objectives. The first concerns mind wandering, or how our thoughts often drift away from our on-going task at hand. We now know that when we mind wander, our attention to the outside world dramatically falls off. A new set of studies more carefully characterizes these ebbs and flows in our attentional states, and examines whether they extend to other periods of inward-directed thought, such as when recalling a memory or reasoning through a problem. The second objective concerns how attention is impacted by physical activity. While we know that single bouts of exercise and long-term exercise habits can boost cognition, we have just found that attentional function also positively varies with one's weekly levels of physical activity. A second set of studies builds on this by examining how individual variability in everyday physical activity levels impacts both attention and brain function. Finally, the third objective concerns understanding individual variability in attentional sensitivities or visual "triggers". In particular, we have recently confirmed that more than 30% of UBC students report having aversive responses to seeing the fidgeting behaviors of others. A final set of studies examines this phenomenon more closely by combining subjective attentional reports with objective, behavior- and brain-based measures of attentional function. Importantly, my proposal doesn't just address open issues in basic research, but it has the potential to benefit all Canadians through its clinical and public health implications. What we learn about mind wandering can help to better understand mental health challenges such as depression and attention deficit hyperactivity disorders. What we learn about physical activity and its impacts on attention can help nudge people towards more health-positive lifestyle choices. And in studying attentional sensitivities, we are validating an unrecognized problem many have heretofore been silently enduring. But taken together, the research doesn't just promise to help advance basic neurocognitive science and fuel its clinical/health applications, but the scope of the projects themselves represent an outstanding opportunity for training the next generation of Canadian cognitive neuroscientists.
从在冰箱里找到一个苹果,到注意到交通信号灯变红,我们如何关注周围的世界对日常生活至关重要。从认知神经科学的角度进行研究,长期以来,注意力的研究一直专注于描述我们大脑中的基本系统,这些系统用于选择和优先处理哪些感觉信息,将哪些感觉信息传递给我们大脑中容量有限的更高水平的处理资源。为了促进我们在这方面的理解,我的建议的目标是探索我们与外部世界的注意力参与是如何随着时间的推移自然地起伏的,以及哪些因素导致这些注意力动态的个体变异性。我的建议有三个值得称赞的目标。第一个问题是走神,或者说我们的思想如何经常偏离手头正在进行的任务。我们现在知道,当我们走神时,我们对外部世界的注意力会戏剧性地下降。一组新的研究更仔细地描述了我们注意力状态中的这些起伏,并检查了它们是否延伸到内向思维的其他时期,例如回忆记忆或通过问题进行推理时。第二个目标是体力活动对注意力的影响。虽然我们知道单次锻炼和长期锻炼习惯可以提高认知能力,但我们刚刚发现,注意力功能也与一个人每周的体育活动水平呈正相关。第二组研究以此为基础,考察了日常体力活动水平的个体变异性如何影响注意力和大脑功能。最后,第三个目标是了解个体在注意敏感度或视觉“触发因素”上的差异。特别是,我们最近证实,超过30%的UBC学生报告说,看到其他人的坐立不安行为,他们有厌恶的反应。最后一组研究通过将主观注意力报告与客观的、基于行为和大脑的注意力功能测量相结合,更密切地研究了这一现象。重要的是,我的建议不仅解决了基础研究中的公开问题,而且有可能通过其临床和公共卫生影响使所有加拿大人受益。我们对走神的了解有助于更好地理解精神健康挑战,如抑郁症和注意力缺陷多动障碍。我们对体育活动及其对注意力的影响的了解,可以帮助推动人们选择更有利于健康的生活方式。在研究注意力敏感度的过程中,我们验证了一个许多人到目前为止一直默默忍受的未被认识的问题。但总而言之,这项研究不仅承诺帮助推进基础神经认知科学,并推动其临床/健康应用,而且这些项目本身的范围也代表着培训下一代加拿大认知神经科学家的绝佳机会。
