thomas01b


This data set contains the results of a full-report face recognition experiment reported in Thomas (2001). For Observer B, the two channels are degree of eye separation and mouth width.


Tools associated with General
Recognition Theory (Townsend & Ashby, 1986), including Gaussian model fitting of 2x2 and more
general designs, associated plotting and model comparison tools,
and tests of marginal response invariance and report independence.

Functions for Analysis of Data with General Recognition Theory

thomas01b function

a <code>matrix</code> instance, containing counts for all stimulus-response combinations. Each row corresponds to a different stimulus presentation (in the order aa, ab, ba, bb) and each column in that row represents the frequency of each response (in the order aa, ab, ba, bb).
