How many choices are subjects making?

The OP has now said that the number of choices varies by subject.

If it is a large enough number,
a relatively easy way to see graphically if your hypothesis is
supported would be to create convenient sized bins, and plot the
proportion of A-responses in each bin. Depending on how that looks,
maybe something as simple as repeated measures ANOVA (with trend
analysis) would work.


Here's another way to plot the data that does not require binning.
Let X = trial number, and let Y = the cumulative number of times A has
been chosen. If the OP's hypothesis is correct, the slope should be
close to 1 early on, and less steep (or even flat) later on.
