Alais D, OShea R, Wilson I
Perception
. 2001 Mar;
29(12):1437-45.
PMID: 11257967
Diaz-Caneja (1928) made some prescient observations about binocular rivalry. Being in French, however, his paper remained largely unknown to the broader research community. His findings are similar to those reported...

Galvin S, OShea R, Squire A, Hailstone D
Vision Res
. 1999 Sep;
39(16):2649-57.
PMID: 10492827
In a previous study we found that blurred edges presented in peripheral vision look sharper than when they are looked at directly, a phenomenon we have called peripheral sharpness overconstancy...

Broerse J, Vladusich T, OShea R
Vision Res
. 1999 May;
39(7):1305-20.
PMID: 10343844
Broerse and O'Shea [(1995) Vision Research, 35, 207-226] proposed that the subjective colours in McCollough effects (MEs) consist of two components: edge colours appearing along the edges of contours, and...

Galvin S, OShea R, Squire A, Govan D
Vision Res
. 1997 Aug;
37(15):2035-9.
PMID: 9327051
Although much has been learned about the spatial sampling and filtering properties of peripheral vision, little attention has been paid to the remarkably clear appearance of the peripheral visual field....

OShea R, Govan D, Sekuler R
Perception
. 1997 Jan;
26(5):599-612.
PMID: 9488884
Studies have shown that blur can act as a pictorial cue to depth perception. But blurring a stimulus reduces its contrast, and studies have also shown that contrast can act...

OShea R, Sims A, Govan D
Vision Res
. 1997 Jan;
37(2):175-83.
PMID: 9068818
We measured binocular rivalry between dichoptic, orthogonal, sinusoidal gratings both having spatial frequencies of 0.5, 1, 2, 4, 8 or 16 c deg-1 in fields ranging from 0.5 to 8...

OShea R, Williams D
Vision Res
. 1996 Jun;
36(11):1561-71.
PMID: 8759459
To test whether the binocular contour rivalry mechanism is tritanopic, we presented isoluminant, rival stimuli visible only via the short-wavelength-sensitive (S) cones. We stimulated only the S cones with violet...

Timney B, Symons L, Wilcox L, OShea R
Vision Res
. 1996 Mar;
36(5):707-15.
PMID: 8762301
Lehmkuhle and Fox [(1976) Vision Research, 16, 428-430] reported that interocular transfer (IOT) of a translational motion aftereffect (MAE) was greater if the non-adapting eye viewed an equiluminant field than...

Broerse J, OShea R
Vision Res
. 1995 Jan;
35(2):207-26.
PMID: 7839617
Dodwell and O'Shea's [(1987) Vision Research, 27, 569-580] conclusions that contingent coloured aftereffects (CAEs) depend on gobal pattern organization were investigated in four experiments. In Expt 1, we replicated findings...

OShea R, Blackburn S, Ono H
Vision Res
. 1994 Jun;
34(12):1595-604.
PMID: 7941367
One consequence of aerial perspective is that far objects have lower contrast than near objects. We tested the efficacy of contrast as a cue for depth perception by measuring the...
