[HTML][HTML] Distinct visual motion processing impairments in aging and Alzheimer's disease
V Kavcic, W Vaughn, CJ Duffy - Vision research, 2011 - Elsevier
Aging and Alzheimer's disease (AD) are associated with declines in the visual perception of
self-movement that undermine navigation and independent living. We studied 214 subjects' …

[HTML][HTML] Crowding in a detection task: external noise triggers change in processing strategy
R Allard, P Cavanagh - Vision research, 2011 - Elsevier
External noise paradigms have been widely used to probe different levels of visual
processing (Pelli & Farell, 1999). A basic assumption of this paradigm is that the processing …
