视觉空间处理速度是多种认知功能的基础，这些功能对于成功完成日常任务（包括驾驶和步行）至关重要。虽然人们普遍认为视觉空间处理速度在成年早期达到顶峰，但整个生命周期的表现仍未完全表征。此外，仍然缺乏可用于评估无监督的基于网络的测试环境中的视觉空间处理速度的范例。为了解决这些差距，我们开发了一种新颖的视觉空间处理速度（VIPS）任务，该任务改编自对老年人视觉空间处理速度下降敏感的两项测试，即有用视野范式和性能中心便携式测试。 VIPS任务要求参与者进行中心方向辨别并同时完成外围视觉搜索任务。从 86 名实验室志愿者（18-30 岁）收集数据，以将表现与传统神经心理学测量进行比较。与之前的文献一致，新颖的 VIPS 任务的表现与选择性注意力、执行功能、视觉速度和工作记忆的测量显着相关。 TestMyBrain.org 还招募了 4395 名志愿者（12-62 岁），以建立视觉空间处理速度的寿命轨迹以及与功能障碍的关联。 VIPS 任务表现在 20 岁出头达到顶峰，然后稳步下降，因此 60 岁的人的阈值相对于 20 岁的人翻了一番（817 毫秒 vs. 412 毫秒）。 VIPS 任务表现与自我报告的整个生命周期的认知功能缺陷显着相关，但与中年的行动问题特别相关。这些发现对于早期发现认知能力下降具有重要意义，并为年轻人和中年人的潜在早期干预目标提供了见解。
Visuospatial processing speed underlies several cognitive functions critical for successful completion of everyday tasks, including driving and walking. While it is widely accepted that visuospatial processing speed peaks in early adulthood, performance across the lifespan remains incompletely characterized. Additionally, there remains a lack of paradigms available to assess visuospatial processing speed in unsupervised web-based testing environments. To address these gaps, we developed a novel visuospatial processing speed (VIPS) task adapted from two tests sensitive to visuospatial processing speed declines in older adults, the Useful Field of View paradigm and the PERformance CEntered Portable Test. The VIPS task requires participants to make a central orientation discrimination and complete a simultaneous peripheral visual search task. Data were collected from 86 in-lab volunteers (18–30 years) to compare performance to traditional neuropsychological measures. Consistent with previous literature, performance on the novel VIPS task significantly correlated with measures of selective attention, executive functioning, visual speed, and working memory. An additional 4395 volunteers (12–62 years) were recruited on TestMyBrain.org to establish lifespan trajectories of visuospatial processing speed and associations with functional disability. VIPS task performance peaked in the early 20’s, and steadily decreased such that thresholds doubled in 60-year-olds relative to 20-year-olds (817 ms vs. 412 ms). VIPS task performance significantly correlated with self-reported cognitive functioning deficits broadly across the lifespan but was specifically related to mobility issues in middle-age. These findings have important implications for early detection of cognitive decline and provide insights into potential early intervention targets for younger and middle-aged adults.
