Compare Two Arrays
The Compare 2 Arrays module is used to compare two image lists, head-to-head. This module could be used in a modified Round Robin comparison approach to hard-code specific comparisons. It could also be used in a 2AFC approach where both the baseline and the test images vary as a function of the stimuli, e.g., as a function of spatial frequency or physical size of the stimuli under study.
