Abstract S. Koppell (see record 1976-29070-001) claims that R. Pike's (see record 1973-20129-001) multiple-observations model for signal detection can be conceived as giving rise to a "latency function," whereby the latency of response decreases with distance of the median position of the observations from the criterion point. It is demonstrated that while this claim is correct, the form of the latency function generated by the model is different in important respects from that usually described by the more general latency-function hypothesis-in particular, it is a dual-valued function-and this difference in form is important in terms of predictions of the multiple-observations model as compared with predictions to be made of the general latency-function hypothesis. The form of the function is derived by means of a consideration of order statistics and is shown to be quite general. The possibility of considering the mean of the sample of observations as generating a latency function is discussed, and the relationship between the mean or median to confidence judgments is considered.
