Auditory mechanisms automatically detect both basic features of sounds and the rules governing their presentation. In the oddball paradigm, the auditory system detects the "sameness" (or no-variability) rule when the same reference tone is consistently repeated. We now used two oddball protocols, the classical one with a fixed reference, and a modified one with a jittered reference to determine whether the auditory system can detect sub-threshold violations of "sameness". We found that the response to the repeated standard was not modified by the small jitter. However, the response to the frequency oddball was smaller under the jittered protocol, indicating hypersensitivity to "sameness". The sensitivity to jitter was largest when the oddball deviated by 8%, smaller for 40% and disappeared at 100% deviation, indicating that sensitivity to "sameness" is context dependent; namely, it is scaled with respect to the overall range of stimuli.
