Title: Spoken word recognition processes and the gating paradigm
Abstract: Words varying in length (one, two, and three syllables) and in frequency (high and low) were presented to subjects in isolation, in a short context, and in a long context. Each word was presented repeatedly, and its presentation time (duration from the onset of the word) increased at each successive pass. After each pass, subjects were asked to write down the word being presented and to indicate how confident they were about each guess. In addition to replicating a frequency, a context, and a word-length effect, this “gating” paradigm allowed us to study more closely the narrowing-in process employed by listeners in the isolation and recognition of words: Some delay appears to exist between the moment a word is isolated from other word candidates and the moment it is recognized; word candidates differ in number and in type from one context to the other; and, like syntactic processing, word recognition is strewn with garden paths. The active direct access model proposed by Marslen-Wilson and Welsh is discussed in light of these findings.
