Dichotic listening refers to the phenomenon in which a person is presented with two different auditory stimuli, one in each ear, and is asked to focus on one while ignoring the other. This technique is often used in psychology research to study attention and perception. Some synonyms for dichotic listening include binaural listening, dual-ear listening, and stereo listening. These terms all describe the same concept of presenting different sounds to each ear and studying the way the brain processes and filters the information. Other related terms include selective attention, auditory processing, and split attention. By studying dichotic listening, researchers hope to gain a better understanding of how the brain works and how we perceive the world around us.
