This data set contains the results of a 3x3 full-report face recognition experiment reported in Thomas et al (2015). The two channels are degree of eye separation and nose width, with three levels on each dimension.
xtabs instance, containing counts for all stimulus-response combinations.
The first two dimensions consist of the response counts on each level of nose width and eye separation, respectively, and the third dimension indexes the stimulus.
