概括

老年人由于视觉处理延迟而表现出受损的导航能力. 虽然年轻人提高了重定向的注意力,但老年人为地标处理招募了更多的神经资源.

科学领域:

认知神经科学认知神经科学
人类衰老研究研究

背景情况:

已知与年龄相关的导航缺陷,但潜在的大脑动态需要进一步研究.
以前的fMRI研究表明,老年人大脑相关区域的活性增加.

研究的目的:

在基准重定位期间调查与年龄相关的大脑动态的差异.
区分参与被动场景感知与主动地标使用的神经过程.

主要方法:

分析了与事件相关的潜力 (ERP) 和与事件相关的光谱扰动 (ERSP).
28名年轻人和28名老年人执行了重新定位和被动场景感知任务.

主要成果:

年长的成年人表现出较差的重定向性能和延迟的早期视觉处理标记.
缩小标志尺寸会影响表现,并延迟早期视觉处理 (P1组件) 在老年人中显著增加.
神经标记的年龄相关差异在很大程度上存在于被动场景感知过程中,而不仅仅是在里程碑使用过程中.

结论:

老年人的导航缺陷可能源于视觉空间信息处理的延迟.
年轻的成年人将更多的注意力资源用于重新定位,而老年人则使用更多的神经资源来处理里程碑.

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
