Abstract:
As the global population ages, understanding of the effect of aging on visual perception is of growing importance. This study investigates age-related changes in adulthood along size perception through the lens of three visual illusions: the Ponzo, Ebbinghaus, and Height-width illusions. Utilizing the Bayesian conceptualization of the aging brain, which posits increased reliance on prior knowledge with age, we explored potential differences in the susceptibility to visual illusions across different age groups in adults (ages 20-85 years). To this end, we used the BTPI (Ben-Gurion University Test for Perceptual Illusions), an online validated battery of visual illusions developed in our lab. The findings revealed distinct patterns of age-related changes for each of the illusions, challenging the idea of a generalized increase in reliance on prior knowledge with age. Specifically, we observed a systematic reduction in susceptibility to the Ebbinghaus illusion with age, while susceptibility to the Height-width illusion increased with age. As for the Ponzo illusion, there were no significant changes with age. These results underscore the complexity of age-related changes in visual perception and converge with previous findings to support the idea that different visual illusions of size are mediated by distinct perceptual mechanisms.
摘要:
随着全球人口老龄化,了解衰老对视觉感知的影响越来越重要。这项研究通过三种视觉错觉的镜头调查了成年期与年龄相关的尺寸感知变化:Ponzo,艾宾浩斯,和高度-宽度的幻想。利用老化大脑的贝叶斯概念化,随着年龄的增长,对先验知识的依赖增加,我们探讨了不同年龄组(20~85岁)成年人视觉错觉易感性的潜在差异.为此,我们使用了BTPI(本-古里安大学知觉幻觉测试),我们实验室开发的在线验证的视觉错觉电池。研究结果揭示了每种错觉的不同年龄相关变化模式,挑战随着年龄的增长,对先验知识的依赖普遍增加的想法。具体来说,我们观察到,随着年龄的增长,对艾宾浩斯错觉的易感性有系统的降低,而对高度-宽度错觉的易感性随着年龄的增长而增加。至于庞佐错觉,随着年龄的增长没有显著的变化。这些结果强调了与年龄相关的视觉感知变化的复杂性,并与先前的发现趋同,以支持以下观点:不同的视觉错觉大小是由不同的感知机制介导的。
