The authors presented photographs of unfamiliar faces of three different sizes to enhance the low, middle, or high facial frequency information (cycles per face). Patients with AD demonstrated normal discrimination of small faces only, indicating that impaired contrast sensitivity at low facial frequencies contributes to their poor face discrimination. Key words: AD—Vision—Face discrimination—Contrast sensitivity—Cognition—Perception. This article has been cited by other articles:
