The specific gray shades in a visual scene can be derived from relative luminance values only when an anchoring rule is followed. The double-anchoring theory I propose in this article, as a development of the anchoring theory of Gilchrist et al. (1999), assumes that any given region (a) belongs to one or more frameworks, created by Gestalt…

Six experiments apply the masked priming paradigm to investigate how letter position information is computed during printed word perception. Primes formed by a subset of the target's letters facilitated target recognition as long as the relative position of letters was respected across prime and target (e.g., "arict" vs. "acirt" as primes for the…

Choroidal neovascularization is a rare condition where aberrant blood vessels behind the retina grow and then bleed, eventually becoming blind areas called Fuchs' spots. A woman suffering from this rare eye disease speaks about the challenges of coping with the visual disability and her determination to make the best of what life has to offer.

This paper reviews two studies of color preference and the relationships between color and legibility. The Gustin study in 1991 dealt with the legibility of and preference for projected slides with colored backgrounds and white text. The order of background color preference was cyan, blue, green, yellow, magenta, and red. The follow-up study by…

One possible explanation of the differences between blind and sighted persons (McKinney, 1964; Attneave & Benson, 1969; Warren, 1970) is that vision is the primary spatial reference, and inputs from other modalities are fitted to a visual map. Several criticisms of this theory are adduced. (Editor/RK)

This study identified new methodological variables which might affect the responses of second and third grade children to Piagetian conservation tasks. (GO)

Reports three experiments in infant visual perception which studied the processes underlying infants' shifts of fixation from one object to another. (JMB)

Differences in the rates of visual information-processing in 8- and 10-year-old reflective and impulsive children were measured. (JMB)

Compared the ability of poor and good readers in the second grade to make same-different matches of visual, auditory, and visual-auditory stimuli. (JMB)

Metacontrast has been the subject of two neural network simulations by Weisstein and Bridgeman. This article compared and elaborated on the two models, corrected flaws not inherent in the models' conceptualizations, and discussed the remaining shortcomings. (Editor/RK)

The effectiveness of delayed static and dynamic visual feedback is assessed through blind maze tracing tasks. (JS)

Confirmed that the superiority of 33 good visualizers over 30 poor visualizers in spelling performance would be more pronounced for "v" words than for "p" words. (RB)
