| Abstract | Presented 10 experienced adult Ss with pairs of stimulus syllables, or isolated transitions from them, which differed in the initial 60 msec of the signals by 0, 7.5, or 9 db. In the syllable context, the intensity differences were discriminated essentially at chance; in both the vowel and isolated transition conditions, the intensity differences were discriminated essentially perfectly. This outcome suggests that after the acoustic features of a stop-consonant-vowel syllable have been recorded into a phonetic representation, the acoustic information is relatively inaccessible for recall from auditory short-term memory. |
