The index of detectability d′ was estimated from data collected with various psychophysical procedures, specifically, the forced-choice method with different numbers of alternatives, and the yes-no method. The estimates were, in all instances, quite comparable. This result is comforting in view of the fact that none of the other indices extant provide a unification of data collected with different procedures. This result is also somewhat surprising view of the fact that the calculation of d′ assumes perfect memory, and forced-choice experiments were conducted with as many as eight temporal alternatives.
