Suppose we have a word recognition task, on the basis of which we compute the four rates defined in Signal Detection Theory as Hits, False Alarms, Correct Rejections, and Misses (HR, FAR, CRR, MR). Due to some reasons, a researcher decides to use only CRR as a dependent variable for the data analysis. What are the underlying processes which are tapped by CRR? Is it just accuracy? If so, then perhaps wouldn't it be complete if HR aren't included into it?
