He also further suggested on the basis of his work that due to the limited capacity, the information processing system for human selects which stimuli channel to attend to which later on led to the derivation of the filter model of attention.ĭoreen Kimura, in the 1960s, drew conclusions about lateral asymmetry in the brain of auditory processing using dichotic listening tests. ![]() The first scientist to systematically use the dichotic listening test in his work was Donald Broadbent.ĭuring the 1950s, Broadbent asked participants in his test to either focus on one or both of the sequence of digits by employing the dichotic listening test during his studies of attention. In this article we will discuss Dichotic Listening. Here the participant is asked to focus on both of the sounds and later on are asked either about one of the stimuli or both of them in case they were not asked to ignore one of the stimuli. The general setup of a standard dichotic listening test is such that the participant taking part in the tst is presented with two different stimuli simultaneously into different ears of the participant using headphones. ![]() This test is mostly used in the field of neuroscience and cognitive psychology. The type of psychological test which is commonly used to investigate the lateralization of brain and selective attenuation within the auditory system of the brain is known as Dichotic listening.
