Popis:	Estimates of the accuracy of a threshold obtained from a psychometric function are often based on asymptotic theory. When the number of trails is small, however, these estimates may be untrustworthy. A computer program is described that uses a move reliable bootstrap approach to obtaining estimates of the standard deviation and confidence limits of a threshold and of the slope and spread of the psychometric function for any criterion level of performance.
