Dichotic Listening

Dichotic listening (pronounced: /daɪˈkɒtɪk ˈlɪsənɪŋ/) is a psychological test commonly used in the field of Cognitive Psychology and Neuropsychology. The term is derived from the Greek words "dicho" meaning "in two" and "otic" meaning "ear".

Overview

In a dichotic listening test, two different auditory stimuli (usually speech) are presented to the subject simultaneously, one to each ear. The subject is then asked to repeat or recall the information heard in one ear (the attended channel), while ignoring the information presented to the other ear (the unattended channel). This method is used to study selective attention and the lateralization of brain function.

History

The dichotic listening technique was first introduced by British scientist Colin Cherry in the 1950s. Cherry used this method to study the cocktail party effect, a phenomenon where people are able to focus their auditory attention on a particular stimulus while filtering out a range of other stimuli.
