In studying visual perception, we seek to develop models of processing that accurately
predict perceptual judgments. Much of this work is focused on judgments of discrimination …

Highlights•The color appearance of a surface depends not only on its local chromaticity but
also on contextual information.•Local and contextual influences on color appearance …

There is a surprisingly strong effect on color appearance when low levels of luminance
contrast are added to visual targets in which only S-cones are modulated. This phenomenon …

A central question in psychophysical research is how perceptual differences between stimuli
translate into physical differences and vice versa. Characterizing such a psychophysical …

The watercolor effect (WCE) is a striking visual illusion elicited by a bichromatic double
contour, such as a light orange and a dark purple, hugging each other on a white …

Surface color appearance depends on both local surface chromaticity and global context.
How are these inter-dependencies supported by cortical networks? Combining functional …

Perceptual filling-in for vision is the insertion of visual properties (eg, color, contour,
luminance, or motion) into one's visual field, when those properties have no corresponding …

Conjoint measurement was used to investigate the joint influence of facial gender and facial
age on perceived gender (Experiment 1) and perceived age (Experiment 2). A set of 25 …

Many children and educated adults experience difficulties in understanding and
manipulating fractions. In this study, we argue that a major cause of this challenge is rooted …

I applied the methodology known as maximum likelihood conjoint measurement (MLCM) to
diagnose how numerical magnitude affects the perception of physical size of numerals in the …
