Examined the speed-accuracy trade-off functions for absolute judgment tasks containing 2, 4, or 8 equally likely response alternatives, with 12 high school seniors as Ss. The rate of gain of information estimated from each of these functions was found to be similar to that estimated by varying the number of alternatives across accuracy emphasis conditions. 2 factors, general response bias and response repetitions, were suggested to account for this relationship. Each factor was shown to vary reliably with both speed emphasis and number of alternatives, but neither effect appeared to be large enough to modify substantially either RT or information transmission.
