Visual Perspective in Memories for Events

据估计，全球每天有9300万张自拍(即用相机自拍)。当我们自拍时，我们在有意识的体验中无意中改变了我们的视觉视角--看到了当下的自己，而不是直接体验到它。由于Skype、视频游戏和沉浸式虚拟现实等技术的进步，我们视觉视角的这种转变现在无处不在。然而，同时身处两个地方可能不利于我们对经历形成持久的记忆。目前的提案将研究从多个视觉角度形成记忆如何影响对现实世界事件的长期记忆起作用的特征和大脑机制。该项目将操纵视觉视角，同时人们对使用身临其境的虚拟现实耳机呈现的真实世界事件的三维360度视频形成记忆。然后，它将测试从多个视觉角度形成记忆如何影响记忆的主观评级和准确性，以及支持记忆形成的相关大脑区域。该项目的完成将为记忆中视觉透视的起源提供完整的图景，从而极大地促进记忆理论的发展。这项基础研究的结果将提供一些发现，可能有助于解决未来关于精神健康中视觉视角障碍的争论。更广泛地说，理解记忆中视觉视角的基础机制可能会通过采用另一种视觉视角提供一种新的方式来理解世界，从而导致社会问题(如冲突、刻板印象、种族关系和同理心)的积极变化。

A staggering 93 million selfies (i.e., a self-portrait with a camera) are estimated to be taken worldwide each day. When we take selfies we inadvertently shift our visual perspective during conscious experience-seeing ourselves in the moment rather than directly experiencing it. Such shifts in our visual perspective are now ubiquitous due to advances in technology, such as Skype, video games, and immersive virtual reality. However, being in two places at once may be detrimental to how we form durable memories of our experiences. The current proposal will investigate how forming memories from multiple visual perspectives influences the characteristics and brain mechanisms that contribute to long-term memories for real-world events. This project will manipulate visual perspective while people form memories for three-dimensional, 360° videos of real-world events that are presented using an immersive virtual reality headset. It will then test how forming memories from multiple visual perspectives influences subjective ratings and the accuracy of memories, and the associated brain regions that support the formation of memories. Completion of the project will significantly advance memory theory by providing a full picture of the origin of visual perspective in memories. The results from this basic research will provide findings that may help to resolve debate regarding visual perspective impairments in mental health in the future. More widely, understanding the mechanisms underpinning visual perspective in memory might lead to positive change in societal issues (e.g., conflict, stereotypes, race relations, and empathy) by offering a new way to understand the world through adopting an alternative visual perspective.
