Abstract
We examined the impact of listening context (sound duration and prior
presentation) on the human perception of segmentation in sequences of computer
music. This research extends previous work by the authors (Bailes & Dean, 2005),
which concluded that context-dependent effects such as the asymmetrical detection of
an increase in timbre compared to a decrease of the same magnitude have a significant
bearing on the cognition of sound structure. The current study replicated this effect,
and demonstrated that listeners (N = 14) are coherent in their detection of segmentation
between real-time and retrospective tasks. In addition, response lag was reduced from a
first hearing to a second hearing, and following long (7 s) rather than short (1 or 3 s)
segments. These findings point to the role of short-term memory in dynamic structural
perception of computer music.
