Vision and Psychology: Perception, Circadian Rhythms, and Sensory Processing
Overview
This paper examines the relationship between vision and psychology, focusing on how perception operates through feature detector neurons. It covers multiple dimensions of visual perception including color, depth, and motion perception, while also discussing circadian rhythms, biological clocks, sensation versus perception, and classical conditioning principles.
What this coursework covers
- Vision and perception: feature detector neurons and color perception (trichromatic and opponent theories)
- Depth and motion perception: binocular vision, retinal disparity, and visual cortex processing
- Circadian rhythms and biological clocks: 24-hour behavioral and psychological adaptations
- Sensation versus perception: sensory information processing and specific nerve energies
- Synaesthesia and classical conditioning: cross-modal sensory experiences and stimulus-response associations

Vision and Psychology
Name
Institution
The relationship between vision and psychology involves perception. Perception results from the action of several thousands of feature detector neurons with each performing a specialized role (Stangor & Walinga, 2020). The dimensions of vision in psychology are;
Perception of color
The human eye can detect seven million color variations derived from the combination of the primary colors. The color information is relayed by the light wavelength entering the eye, and the wave intensity detects brightness. According to Trichromatic theory, there exist cones in the retina that react to the primary colors to perceive color (Stangor & Walinga, 2020). The opponent theory suggests that some cells are attracted to one opponent color and inhibited by another, and this explains why the eye might perceive specific images in the absence of the stimulus.
Perception of Depth
The depth perspective involves the visual ability to interprate three-dimensional space and appropriately make a judgment on measurements. Our ability to interprate depth depends on the Binocular depth signal by retinal image disparity and the ability of our bodies to give cues about space and distance. Each eye views objects differently, and the cortex merges the two images to perceive it as a unit form (Glezer, 2013).
Perception of Motion
Humans exhibit skills that guide their motion and coordinates with the motion of moving objects to enable collision with the object.
