Hi!
I am using the Y-maze (Spontaneous alternations test) with the Ethovision XT15 software.
I have checked the literature and everyone seem to use the percentage of alternations as actual alternations divided by the maximum number of possible alternations (which is defined by number of arm entries minus 2) multiplied by 100. The software gives you per trial, one value that is called "Max alternations", but it also gives you the frequency of entries in each arm. So for the formula to find the percentage of spontaneous alternations, you can:
1- Divide the actual alternations (also given by the program) and use the value of "Max alternations" and do the minus two, and *100.
2- Or also, what I have tried is to sum the frequency of entries in each arm (total arm entries) and do minus two, and *100.
I was wondering which is your experience, and which is the value that people use in the formula, since this is not described in most of the papers that I have read.
Thanks a lot to all of you in advance!!
