Deficient Biological Motion Perception in Schizophrenia: Results from a Motion Noise Paradigm [PDF]

Frontiers in Psychology, 2013
Background: Schizophrenia patients exhibit deficient processing of perceptual and cognitive information. However, it is not well understood how basic perceptual deficits contribute to higher level cognitive problems in this mental disorder. Perception of

Alcohol and motion perception [PDF]

Perception & Psychophysics, 1982
Three motion perception skills were measured under different levels of alcohol ingestion. Our method for detecting decrements in visual information processing proved sensitive to blood alcohol levels as low as .02%. Alcohol in small doses increased reaction times to the onset of motion, particularly to slow speeds, but did not reduce the ability to ...

Perception of Motion and Architectural Form: Computational Relationships between Optical Flow and Perspective [PDF]

arXiv, 2011
Perceptual geometry refers to the interdisciplinary research whose objectives focuses on study of geometry from the perspective of visual perception, and in turn, applies such geometric findings to the ecological study of vision. Perceptual geometry attempts to answer fundamental questions in perception of form and representation of space through ...

Modality-specific effects of threat on self-motion perception [PDF]

BMC Biology
Background Threat and individual differences in threat-processing bias perception of stimuli in the environment. Yet, their effect on perception of one’s own (body-based) self-motion in space is unknown.

Inverse relation between motion perception and postural responses induced by motion of a touched object [PDF]

Communications Biology
Self vs. external attribution of motions based on vestibular cues is suggested to underlie our coherent perception of object motion and self-motion. However, it remains unclear whether such attribution also underlies sensorimotor responses.

Self-motion perception without sensory motion. [PDF]

Exp Brain Res, 2022
AbstractVarious studies have demonstrated a role for cognition on self-motion perception. Those studies all concerned modulations of the perception of a physical or visual motion stimulus. In our study, however, we investigated whether cognitive cues could elicit a percept of oscillatory self-motion in the absence of sensory motion. If so, we could use

Study on 3D Motion-in-Depth Perception Based on Binocular Vision [PDF]

Jisuanji kexue, 2022
Obtaining stereoscopic information is one of the basic abilities of human beings to perceive the world.Through stereo vision,we can judge the shape,size,distance,relative position of objects,as well as the direction and speed of changes in object motion ...

The neural basis of centre-surround interactions in visual motion processing [PDF]

, 2011
Perception of a moving visual stimulus can be suppressed or enhanced by surrounding context in adjacent parts of the visual field. We studied the neural processes underlying such contextual modulation with fMRI.

The toolish hand illusion: embodiment of a tool based on similarity with the hand

Scientific Reports, 2021
A tool can function as a body part yet not feel like one: Putting down a fork after dinner does not feel like losing a hand. However, studies show fake body-parts are embodied and experienced as parts of oneself. Typically, embodiment illusions have only

The visual perception of motion [PDF]

Current Biology, 2004
Sensing the movements of the world and the objects within it appears to be a fundamental job for our visual system. In rare cases of brain damage, we find that individuals lacking motion perception live in a very different world of frozen images, where simple tasks like filling a kettle or crossing the road take on alarming difficulties.
