Elliott S, Choi S, Doble N, Hardy J, Evans J, Werner J
J Vis . 2009 Mar; 9(2):24.1-16. PMID: 19271934
The contributions of optical and neural factors to age-related losses in spatial vision are not fully understood. We used closed-loop adaptive optics to test the visual benefit of correcting monochromatic...

Delahunt P, Hardy J, Werner J
J Vis . 2008 May; 8(3):5.1-9. PMID: 18484811
Accurately processing orientation information is a fundamental component of visual performance. Single-unit recordings have shown that the orientation tuning of individual neurons in macaque cortical areas V1 and V2 is...

Elliott S, Hardy J, Webster M, Werner J
J Vis . 2007 Aug; 7(6):8. PMID: 17685791
Color appearance remains remarkably stable in the aging visual system despite large changes in the spectral distribution of the retinal stimulus and losses in chromatic sensitivity (P. B. Delahunt, J....

Mahncke H, Connor B, Appelman J, Ahsanuddin O, Hardy J, Wood R, et al.
Proc Natl Acad Sci U S A . 2006 Aug; 103(33):12523-8. PMID: 16888038
Normal aging is associated with progressive functional losses in perception, cognition, and memory. Although the root causes of age-related cognitive decline are incompletely understood, psychophysical and neuropsychological evidence suggests that...

Devinck F, Hardy J, Delahunt P, Spillmann L, Werner J
J Vis . 2006 Aug; 6(5):625-33. PMID: 16881793
The watercolor effect (WCE) is a phenomenon of long-range color assimilation occurring when a dark chromatic contour delineating a figure is flanked on the inside by a brighter chromatic contour;...

Devinck F, Delahunt P, Hardy J, Spillmann L, Werner J
Perception . 2006 May; 35(4):461-8. PMID: 16700289
Color assimilation with bichromatic contours was quantified for spatial extents ranging from von Bezold-type color assimilation to the watercolor effect. The magnitude and direction of assimilative hue change was measured...

Choi S, Doble N, Hardy J, Jones S, Keltner J, Olivier S, et al.
Invest Ophthalmol Vis Sci . 2006 Apr; 47(5):2080-92. PMID: 16639019
Purpose: To relate in vivo microscopic retinal changes to visual function in patients who have various forms of retinal dystrophy. Methods: The UC Davis Adaptive Optics (AO) fundus camera was...

Yamashita J, Hardy J, De Valois K, Webster M
J Exp Psychol Hum Percept Perform . 2005 Jun; 31(3):420-37. PMID: 15982123
Viewing a distorted face induces large aftereffects in the appearance of an undistorted face. The authors examined the processes underlying this adaptation by comparing how selective the aftereffects are for...

Hardy J, Frederick C, Kay P, Werner J
Psychol Sci . 2005 Apr; 16(4):321-7. PMID: 15828980
Many languages without separate terms for green and blue are or were spoken in locations receiving above-average exposure to ultraviolet-B (UV-B) radiation. It has been proposed that this correlation is...

Devinck F, Delahunt P, Hardy J, Spillmann L, Werner J
Vision Res . 2005 Mar; 45(11):1413-24. PMID: 15743611
When a dark chromatic contour delineating a figure is flanked on the inside by a brighter chromatic contour, the brighter color will spread into the entire enclosed area. This is...
