Journal ArticleDOI
Aging and the depth of binocular rivalry suppression.
TL;DR: In this paper, the effect of aging on the strength of binocular rivalry suppression was examined in the presence or absence of a probe spot in the dominant or suppressed eye's view.
Journal ArticleDOI
Aging and the discrimination of 3-D shape from motion and binocular disparity

TL;DR: The results of both experiments showed that younger and older adults possess considerable tolerance to the disrupting effects of volumetric noise; the observers could reliably discriminate 3-D surface shape even when 45 % of the stimulus points (or more) constituted noise.
Journal ArticleDOI
Stereoscopic shape discrimination is well preserved across changes in object size.
TL;DR: It appears that human observers can recognize the three-dimensional shape of objects in a manner that is relatively independent of size.
Journal ArticleDOI
Aging and the perception of local surface orientation from optical patterns of shading and specular highlights
TL;DR: The ability to perceive local surface orientation appears to be relatively well preserved with increasing age, at least through the age of 80.
Journal ArticleDOI
Dynamic cutaneous information is sufficient for precise curvature discrimination.
TL;DR: Curvature discrimination performance was best in the current study when dynamic cutaneous stimulation occurred in the absence of active movement, and for both age groups, the curvature discrimination thresholds obtained for passive touch were significantly lower than those that occurred during active touch.
