Detailed Description

basic data set class

This class holds data from a psychophysical experiment. The experiment can in principle be performed as an nAFC task or as a yes/no task. Typically for an nAFC task, the number of correct responses would be recorded and for a yes/no task the number of yes responses would be recorded. The nomenclature of the class corresponds to the nAFC task.

The block order and number can be crucial under some circumstances, so don't lump multiple blocks into one just because they have the same stimulus intensity.
