Binomial Test that does not assume indepence? (using a repeated measures design)

#1
Hi,

I am looking for a way to analyze data for the following experiment:

subjects were presented with two separate acoustic signals at the same time and the question is which signal do the subjects prefer (signal A or B)?

Subject were presented with the A and B signal combination 5 times and the choice was recorded.

I am also limited by a small sample size (5 subjects) because I am working with an endangered specie.

Any recommendations would be extremely appreciated.
