But I would be more interested in the other direction: is there any additional gain in recognition performace if we use stimuli LONGER than a syllable? What made me wonder about this is the "backwards recognition masking" experiments of Massaro (unfortunately, I don't have the original papers, only a half-page review in a Ph.D. thesis by Brian Kingsbury). Their results say that masking has no effect if the target is longer than a syllable or if there is at least a syllable-long silent interval between the target and the masker. I would need a reinforcement of these results, but possibly from the opposite direction (i.e. not how recognition deteriorates from backwards masking but how recognition improves from "forward helping" - so to say).
