In order to increase perceptual precision the adult brain dynamically combines redundant
information from different senses depending on their reliability. During object size …

When participants are given the opportunity to simultaneously feel an object and see it
through a magnifying or reducing lens, adults estimate object size to be in-between visual …

The preschool years are an important time during which children gain proficiency using the
hands for both performatory and perceptual functions that involve dynamic (kinesthetic) …

A stable representation of object size, in spite of continuous variations in retinal input due to
changes in viewing distance, is critical for perceiving and acting in a real 3D world. In fact …

Is a grapefruit bigger than an apple? How do you know? People have little difficulty in
comparing objects in this way, but the nature of the underlying size representations remains …

When visual information is available, human adults, but not children, have been shown to
reduce sensory uncertainty by taking a weighted average of sensory cues. In the absence of …

Size perception can be influenced by several visual cues, such as spatial (eg, depth or
vergence) and temporal contextual cues (eg, adaptation to steady visual stimulation) …

It is still unclear whether size constancy is an innate ability or whether it develops with age.
As many developmental studies are limited to the child's comprehension of the task …

Touch delivers a wealth of information already from birth, helping infants to acquire
knowledge about a variety of important object properties using their hands. Despite the fact …

It is still unclear how the visual system perceives accurately the size of objects at different
distances. One suggestion, dating back to Berkeley's famous essay, is that vision is …
