Dichotic listening tests typically involve two different auditory stimuli (usually speech) presented simultaneously, one to each ear, using a set of headphones.

In this procedure, participants are presented with a stream of auditory stimuli: including frequent, standard stimuli as well as infrequent, target stimuli.

These effects are found for both visual and auditory stimuli in memory tasks.

It synthesizes and shows accurately controlled visual and auditory stimuli and interacts with the observer.

They also play a role in emotion and learning and are concerned with processing and interpreting auditory stimuli.
