Backward masking, the suffix effect, and preperceptual storage.
This article considers the use of auditory backward recognition masking (ABRM) and stimulus suffix experiments as indexes of preperceptual auditory storage. In the first part of the article, two ABRM experiments that failed to demonstrate a mask disinhibition effect found previously in stimulus suffix experiments are reported. The failure to demonstrate mask disinhibition is inconsistent with an explanation of ABRM in terms of lateral inhibition. In the second part of the article, evidence is presented to support the conclusion that the suffix effect involves the contributions of later processing stages and does not provide an uncontaminated index of preperceptual storage. In contrast, it is claimed that ABRM experiments provide the most direct index of the temporal course of perceptual recognition. Partial-report tasks and other paradigms are also evaluated in terms of their contributions to an understanding of preperceptual auditory storage. Differences between interruption and integration masking are discussed along with the role of preperceptual auditory storage in speech perception.
