Question

Write a short note on the Dichotic Listening Test. Explain why it is useful. (5)

Answer 1

The Dichotic listening test is a psychological test commonly used to investigate selective attention within the auditory system and is a subtopic of cognitive psychology and neuroscience. Specifically, it is "used as a behavioral test for hemispheric lateralization of speech sound perception." During a standard dichotic listening test, a participant is presented with two different auditory stimuli simultaneously (usually speech). The different stimuli are directed into different ears over headphones. Research Participants were instructed to repeat aloud the words they heard in one ear while a different message was presented to the other ear. As a result of focusing to repeat the words, participants noticed little of the message to the other ear, often not even realizing that at some point it changed from English to German. At the same time, participants did notice when the voice in the unattended ear changed from a male’s to a female’s, suggesting that the selectivity of consciousness can work to tune in some information."
