Binocular rivalry
Binocular Rivalry
Binocular rivalry (/bɪˈnɒkjʊlər ˈraɪvəlri/) is a phenomenon of visual perception in which perception alternates between different images presented to each eye.
Etymology
The term "binocular rivalry" is derived from the Latin words "bini" meaning 'two' and "oculus" meaning 'eye', and the English word "rivalry" which refers to competition or antagonism. Thus, it refers to the competition between the two eyes for visual perception.
Definition
Binocular rivalry is a phenomenon that occurs when two different images are presented to each eye simultaneously, typically using a method known as dichoptic presentation. The brain cannot fuse the two images into a single perception, leading to an alternation between the two images in conscious awareness. This alternation can occur spontaneously and unpredictably, and can last from a few seconds to a few minutes.

Research
Research into binocular rivalry provides insights into the mechanisms of visual perception and conscious awareness. It has been used as a tool to explore the neural correlates of consciousness, the processes of attention, and the organization of the visual system.
