Fig. 2: Illustration of the principle of Signal detection theory.

A Illustration of the principle of Signal detection theory. B Sensitivity d’ and (C) Criterion C are calculated based on the Hit and Miss rate. A higher d’ indicates better performance while lower Criterion C indicates a stronger preference for false alarms compared to misses. D Percentage correct. E Response time of correct trials (high tones) and its intra-subject variability. F Correlation between response time and Criterion C.
