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 …

Research on functional changes across the adult lifespan has been dominated by studies
related to cognitive processes. However, it has become evident that a more comprehensive …

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

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 …

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

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 …

Aging impacts human observer's performance in a wide range of visual tasks and notably in
motion discrimination. Despite numerous studies, we still poorly understand how optic flow …

Motion-position illusions (MPIs) are visual motion illusions in which motion signals bias the
perceived position of an object. Due to phenomenological similarities between these …

Perceptual functions change with age, particularly motion perception. With regard to healthy
aging, previous studies mostly measured motion coherence thresholds for coarse motion …

Super recognizers (SRs) are people that exhibit a naturally occurring superiority for
processing facial identity. Despite the increase of SR research, the mechanisms underlying …
