The sensitivity index d' measures the distance between the signal and the noise means in standard deviation units. c is the distance of the bias criterion from the point where neither response is favored, also
in standard units. Positive c values indicate a bias towards high hit rates and false alarm rates. Correction of perfect rates according to 1/2N rule is included.
cf. Stanislaw H, Todorov N, Behav Res Meth (1999) 31, 137-149
