Changes in the lower displacement limit for motion with age

Abstract
Previous studies have alleged that the ability to perceive motion remains constant with age. We investigated the effect of age on minimum displacement thresholds using computer-generated random dot stimuli in 91 healthy, visually normal subjects (age range 21-82 years). High and low contrast visual acuity and letter contrast sensitivity were also tested. We found that minimum displacement thresholds increased significantly at a rate of 0.07 log min arc per decade (approximately 17%). The relationship between age and performance was very similar for all visual tests.

Citation countsare sourced monthly from Scopus and Web of Science citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
