Bringing precision to the understanding and treatment of mental disorders requires
instruments for studying clinically relevant individual differences. One promising approach is …

The processing of multisensory signals is crucial for effective interaction with the
environment, but our ability to perform this vital function changes as we age. In the first part …

Human perceptual decisions are often described as optimal. Critics of this view have argued
that claims of optimality are overly flexible and lack explanatory power. Meanwhile …

Despite well-established sex differences for cognition, audition, and somatosensation, few
studies have investigated whether there are also sex differences in visual perception. We …

This article reviews theoretical and empirical arguments for and against various theories that
explain the classic Ponzo illusion and its variants from two different viewpoints concerning …

There seems to be no common factor for visual perception, ie, performance in visual tasks
correlates only weakly with each other. Similar results were found with visual illusions. One …

Most people like symmetry, and symmetry has been extensively used in visual art and
architecture. In this study, we compared preference for images of abstract and familiar …

We recently found only weak correlations between the susceptibility to various visual
illusions. However, we observed strong correlations among different variants of an illusion …

There is recent evidence for a domain-general object recognition ability, called O, which is
distinct from general intelligence and other cognitive and personality constructs. We extend …

Common factors are ubiquitous. For example, there is a common factor, g, for intelligence. In
vision, there is much weaker evidence for such common factors. For example, visual illusion …
