These results provide the first evidence that by 10 months infants can rapidly encode sequences of naturalistic sounds into auditory STM. In many respects, this is remarkable given that our instrument sequences varied only in the spectral properties/attack properties of the sound (e.g., the instrument) and not in absolute pitch. Nonetheless, infant auditory STM capacity appears to be limited to streams composed of at least 2 instruments but not 4 instruments. However, the streams used in Experiment 1 differed not only in the number of instruments per sequence but also in the total duration of each sequence. That is, because all of the notes were 350 ms, the 2-instrument sequence had a total dura- tion of 700 ms, whereas the 4-instrument sequence had a total duration of 1400 ms. It is possible that the total duration of the 4-instrument stream rather than set size per se, may have driven our capacity effect. Work with adults has demonstrated an interesting dissociation between short (
