Size constancy affects the perception and parietal neural representation of object size
NeuroImage, 2021 Humans and animals rely on accurate object size perception to guide behavior. Object size is judged from visual input, but the relationship between an object's retinal size and its real-world size varies with distance.

A Riemannian Geometry Theory of Three-Dimensional Binocular Visual Perception
Vision, 2018 We present a Riemannian geometry theory to examine the systematically warped geometry of perceived visual space attributable to the size⁻distance relationship of retinal images associated with the optics of the human eye.

The Influence of Auditory Information on Visual Size Adaptation
Frontiers in Neuroscience, 2017 Size perception can be influenced by several visual cues, such as spatial (e.g., depth or vergence) and temporal contextual cues (e.g., adaptation to steady visual stimulation).

How haptic size sensations improve distance perception. [PDF]
PLoS Computational Biology, 2011 Determining distances to objects is one of the most ubiquitous perceptual tasks in everyday life. Nevertheless, it is challenging because the information from a single image confounds object size and distance. Though our brains frequently judge distances

Independence of Size and Distance in Binocular Vision
Frontiers in Psychology, 2018 For too long, the size distance invariance hypothesis (SDIH) has been the prevalent explanation for size perception. Despite inconclusive evidence, the SDIH has endured, primarily due to lack of suitable information sources for size perception.

Size perception by vision and kinesthesia [PDF]
Perception & Psychophysics, 1998 When two sizes, one perceived by vision and the other by kinesthesia, are apparently equal, the physical relationship between them varies: The sizes may be equal, or the visual size may be larger than the kinesthetic size, or vice versa. In this study, the method of cross-modal matching and the method of magnitude production were used to explore the ...

The visual perception of size and distance [PDF]
Vision Research, 1963 Abstract The perception of absolute distance has been assumed to be important in the perception of the size of objects and the depth between them. A different hypothesis is proposed. It is asserted that perceived relative size and distance are the primary psychological phenomena with perceived absolute distance derived from the perceptual summing of ...

Effect of Haptic Feedback on the Perceived Size of a Virtual Object
IEEE Access, 2019 We investigate how different types of haptic feedback to hand affect the perceived size of a virtual object. Multiple haptic interfaces are designed to deliver different types of haptic feedback to hand. In the preliminary experiment, we investigated the

Direct and indirect perception of size [PDF]
Perception & Psychophysics, 1980 Three experiments, using a reaction time paradigm, examine the direct (stimulus bound) and indirect (mediational inference) approaches to size perception. Subjects determine which of two stimuli is the larger when the two can be at different egocentric distances.

VIP interneurons regulate cortical size tuning and visual perception
Cell Reports, 2023 Summary: Cortical circuit function is regulated by extensively interconnected, diverse populations of GABAergic interneurons that may play key roles in shaping circuit operation according to behavioral context.
