A characteristic function equation for two-interval forced-choice experiments
William M. Hartmann · The Journal of the Acoustical Society of America · 1980
The percent correct responses in a two-interval forced-choice detection experiment can be calculated from the probability density functions for the excitation on the two intervals. This letter introduces an equation which relates the percent correct responses to the characteristic functions of the probability densities. The equation can result in considerable mathematical simplification in the prediction of detection performance in cases of multiple sources of signal or noise.
