Auditory brainstem response (ABR) audiometry is a neurologic test of auditory brainstem function in response to auditory (click) stimuli. First described by Jewett and Williston in 1971, ABR audiometry is the most common application of auditory evoked responses. Test administration and interpretation is typically performed by an audiologist. This article provides an overview of the test and its most common applications.
The term conditioned emotional response (CER) can refer to a specific learned behavior or a procedure commonly used in classical or Pavlovian conditioning research.It may also be called conditioned suppression or conditioned fear response (CFR)..It is an emotional response that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing unconditional stimulus.As a result, the formerly neutral stimulus elicits fear.n 1920 John B. Watson and Rosalie Rayner demonstrated such fear conditioning in the Little Albert experiment. They started with a 9-month boy called âAlbertâ, who was unemotional but was made to cry by the loud noise (unconditioned stimulus) of a hammer striking a steel bar.
