Abstract: An irrelevant sequence of discrete auditory tokens disrupts serial recall markedly if successive tokens differ, but the disruption is less marked if the sound is repeated. However, the relation of stimulus mismatch and degree of disruption with serial recall seems to be modulated by organizational principles such as streaming by pitch and streaming by location. The current empirical work replicates the finding that the impact of changing sequences can be reduced if tokens are assigned to different locations in such a way as to form separate streams, each containing sequences of repeated tokens. This study shows that this phenomenon is not a consequence of reducing the number of tokens per stream.
