Why Would Numerosity Affect Dissonance?
The Rewards of Complexity:
-
significant perceptual difficulties arise with
increasing # of streams
-
if the parsing of multiple streams is difficult,
why do listeners enjoy multipart music?
-
Huron (2001) proposed that successful parsing of the
auditory scene may result in a positively valenced
limbic response.
-
the brain "rewards itself" for assembling
a coherent representation of the external world
based on the available cues.
-
also proposed that the magnitude of the
limbic "reward" is proportional to the difficulty
of the task.
