RETINAL RIVALRY Meaning and
Definition
-
Retinal rivalry refers to a visual phenomenon characterized by the perceptual alternation of different images presented to each eye. It occurs when contrasting or conflicting visual information is simultaneously presented to the two eyes, leading to the brain perceiving different images from each eye. This rivalry takes place at the level of the retinas, the light-sensitive tissues located at the back of each eye, which send visual signals to the brain.
The process of retinal rivalry involves competition between the two eyes for dominance in the perception of conflicting visual stimuli. As a result, the individual may experience the perceptual switching of the competing images, with one image dominating the conscious perception while the other is suppressed or completely blocked from awareness. This alternation can occur spontaneously or be manipulated experimentally by presenting dissimilar images or patterns to each eye.
Retinal rivalry is often used as a research tool in the study of visual perception to gain insights into the brain's processing of visual information. By examining the dynamics and mechanisms of retinal rivalry, scientists aim to understand how the brain selects and integrates sensory inputs, revealing valuable information about the neural processes involved in perception.
Overall, retinal rivalry highlights the incredible complexity of visual processing and illustrates the brain's ability to resolve conflicting visual information, leading to the dynamic perceptual experiences that we encounter in our daily lives.

Etymology of RETINAL RIVALRY
The term "retinal rivalry" is composed of two words, "retinal" and "rivalry".
1. Retinal: The word "retinal" relates to the retina, which is the light-sensitive tissue lining the inner surfaces of the eye. The retina plays a crucial role in vision, as it receives and processes light signals before transmitting them to the brain.
The term "retinal" is derived from the Latin word "retina", meaning "net" or "net-like structure". This Latin term originated from "rete", which means "net" or "web". The resemblance of the retina's structure to a net or web led to its name.
2. Rivalry: The word "rivalry" comes from the Latin word "rivalis", referring to someone with whom you share a river or a brook.
