Convergence is a binocular oculomotor cue for distance and depth perception. Because of stereopsis, the two eyeballs focus on the same object; in doing so they converge. The convergence will stretch the extraocular muscles – the receptors for this are muscle spindles .
A cue is some organization of the data present in the signal which allows for meaningful extrapolation. For example, sensory cues include visual cues, auditory cues, haptic cues, olfactory cues and environmental cues. Sensory cues are a fundamental part of theories of perception, especially theories of appearance (how things look).
The Necker Cube: The left line drawing can be perceived in one of two distinct depth configurations shown on the right. Without any other cue, the visual system flips back and forth between these two interpretations. [15] A perceptual illusion that can be precisely controlled is binocular rivalry. Here, a small image, e.g., a horizontal grating ...
Interocular transfer occurs in the relational-motion detectors, which are of the binocular or monocular class. The study confirms the presence on interocular transfer of MAE, and localizes the adaptation for MAE in either an individual's eye, or the brain areas which combine the information from both set of eyes.
With binocular vision development, infants between four and five months also develop a sense of size and shape constancy objects, regardless of the objects location and orientation in space. [20] From static cues based upon monocular vision, infants older of five month of age have the ability to predict depth perception from pictorial position ...
The binocular nature of the chromostereopsis was discovered by Bruecke and arises due to the position of the fovea relative to the optical axis. The fovea is located temporally to the optical axis and as a result, the visual axis passes through the cornea with a nasal horizontal eccentricity , meaning that the average ray bound for the fovea ...
Certain cues help establish depth perception. Binocular cues are made by humans' two eyes, which are subconsciously compared to calculate distance. [16] This idea of two separate images is used by 3-D and VR filmmakers to give two dimensional footage the element of depth. Monocular cues can be
When moving about in the dark, they respond to tactual cues from their stiff whiskers (vibrissae) located on the snout. Hooded rats tested on the visual cliff show little preference for either side of the visual cliff apparatus as long as they could feel the glass with their vibrissae.
