Disinhibition of masking in auditory sensory memory

A series of experiments was performed on the difference between single- and double-masking agents in auditory memory. Single or double suffixes were presented following immediate memory lists, with parametric variation in the delay of the suffixes relative to the end of the list. The main interest was in the shape of the masking function produced by the timing of either the single suffix or the second of two suffixes. Disinhibition was shown to occur, although it was weak in absolute magnitude.
