wo89xt


This data set contains a slightly coarse-grained version of Table 1 from Wickens and Olzak (1989).
For each of four possible combinations of stimuli, participants gave a graded confidence judgement (collapsed here to 1-4) on both dimensions concurrently.
A rating of 1 corresponded to "definitely absent" and a rating of 4 corresponded to "definitely present".


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

wo89xt function

an <code>xtabs</code> instance, containing counts for all stimulus-response combinations.
For each of 4 Stim levels (where NN = absent+absent, LN = low-frequency signal+absent, NH = absent+high-frequency signal, LH = low-frequency signal+high-frequency signal),
there is a 4x4 table giving the frequency of each rating.
