Closure and memorability / recognizability?

[Song Hui Chon <shchon@xxxxxxxxxxxxxxxxxx>]

Dear list,

We are in the process of designing an experiment, where subjects will listen to a short segment of 
counterpoint music (with 2- or 3-voices) and answer whether or not the probe melody was in the 
excerpt. The issue of memorability / recognizability came up in a discussion and we are wondering if 
there is any literature on "melody with or without closure and its effect on memorability or 
recognizability". A quick search on Google scholar was not very helpful. And music theorists we 
contacted were not aware of any such work.

Any feedback will be much appreciated.

Thanks,
SongHui Chon.
