“…We did observe a weak tendency for detection thresholds to improve with session number, consistent with findings of other researchers (e.g., Zwislocki et al 1958;Henry et al 2001 and references therein). Because listeners differed in their absolute thresholds, we first calculated for each listener and session the detection threshold (in dB SPL), L T(D) , for the reference stimulus (Methods), and then the difference between the L T(D) of each individual session and the mean L T(D) across all sessions, DL T(D) .…”

An understanding of the auditory system's operation requires knowledge of the mechanisms underlying thresholds. In this work we compare detection thresholds obtained with a three-interval-three-alternative forced-choice paradigm with reaction thresholds extracted from both reaction probabilities (RP) and reaction times (RT) in a simple RT paradigm from the same listeners under otherwise nearly identical experimental conditions. Detection thresholds, RP, and RT to auditory stimuli exhibited substantial variation from session to session. Most of the intersession variation in RP and RT could be accounted for by intersession variation in a listener's absolute sensitivity. The reaction thresholds extracted from RP were very similar, if not identical, to those extracted from RT. On the other hand, reaction thresholds were always higher than detection thresholds. The difference between the two thresholds can be considered as the additional amount of evidence required by each listener to react to a stimulus in an unforced design on top of that necessary for detection in the forced-choice design. This difference is inversely related to the listener's probability of producing false alarms. We found that RT, once corrected for some irreducible minimum RT, reflects the time at which a given stimulus reaches the listener's reaction threshold. This suggests that the relationships between simple RT and loudness (reported in the literature) are probably caused by a tight relationship between temporal summation at threshold and temporal summation of loudness.

“…The psychophysical procedure was the two-interval forcedchoice tracking procedure proposed by Zwislocki et al (4) and executed as follows. The stimulus was presented at random in one of two observation intervals of 720-msec duration, marked by lights of equal duration: the first by a red light and the second by a green one.…”

“…A UDTR method of a different kind, which achieves this target, was proposed ahead of them by Zwislocki et al (4), already in 1958, and was used sporadically in various experiments (4-6) but failed to find general acceptance. Several reasons may account for this result.…”

Tranformed-rule up and down psychophysical methods have gained great popularity, mainly because they combine criterionfree responses with an adaptive procedure allowing rapid determination of an average stimulus threshold at various criterion levels of correct responses. The statistical theory underlying the methods now in routine use is based on sets of consecutive responses with assumed constant probabilities of occurrence. The response rules requiring consecutive responses prevent the possibility of using the most desirable response criterion, that of 75% correct responses. The earliest transformed-rule up and down method, whose rules included nonconsecutive responses, did not contain this limitation but failed to become generally accepted, lacking a published theoretical foundation. Such a foundation is provided in this article and is validated empirically with the help of experiments on human subjects and a computer simulation. In addition to allowing the criterion of 75% correct responses, the method is more efficient than the methods excluding nonconsecutive responses in their rules.two-interval forced choice ͉ adaptive procedure ͉ response rule ͉ nonconsecutive correct responses
