Mathematical Psychology, forced choice, signal detection theory, nAFC
An approximation suitable for computer estimation of d' from the total proportion of correct responses in an n-alternative forced choice experiment for any n is described. This approximation implies that ogival psychometric functions can be interpreted as linear in d', which provides signal detection threshold or sensitivity measures allowing comparisons between psychometric functions with different numbers of stimulus alternatives.
