During the past decade a number of variations in the simple up‐down procedure have been used in psychoacoustic testing. A broad class of these methods is described with due emphasis on the related problems of parameter estimation and the efficient placing of observations. The advantages of up‐down methods are many, including simplicity, high efficiency, robustness, small‐sample reliability, and relative freedom from restrictive assumptions. Several applications of these procedures in psychoacoustics are described, including examples where conventional techniques are inapplicable.read more

A computer model of the auditory-nerve response to forward-masking stimuli
Ray Meddis,Lowel P. O’Mard +1 more
TL;DR: The modeling results suggest that poststimulatory reductions in AN activity can make a substantial contribution to the raised thresholds observed in many psychophysical studies of forward masking.

Impact of Noise and Noise Reduction on Processing Effort: A Pupillometry Study.
TL;DR: The benefit of applying an NR scheme was demonstrated for both L50 and L95, that is, a situation at which the performance level was at a ceiling, which opens the opportunity for new means of evaluating hearing aids in situations in which traditional speech reception measures are shown not to be sensitive.

Effects of practice and signal energy on duration discrimination of brief auditory intervals.
TL;DR: The results of the present study suggest that duration discrimination of brief auditory intervals is based on temporal information and not on stimulus energy, and implications for the notion of a very basic bio-logical timing mechanism underlying temporal processing of Brief auditory intervals in the range of milliseconds are discussed.

Observers exploit stochastic models of sensory change to help judge the passage of time.
Misha B. Ahrens,Maneesh Sahani +1 more
TL;DR: It is suggested that observers routinely rely on sensory input to augment their sense of the passage of time, through a process of Bayesian inference based on expectations of change in the natural environment.

Sensory detection thresholds are modulated across the cardiac cycle: evidence that cutaneous sensibility is greatest for systolic stimulation.
TL;DR: The finding that cutaneous sensibility was greater when stimulated during systole than diastole may be accounted for by a modified afferent feedback hypothesis.

TL;DR: The use of the staircase-method is illustrated, its relative merits and demerits are discussed, and a modification is described which overcomes certain of the disadvantages of the method.

PEST: Efficient Estimates on Probability Functions
M. M. Taylor,C. Douglas Creelman +1 more
TL;DR: In this article, an adaptive procedure for rapid and efficient psychophysical testing is described, with maximally efficient trial-by-trial sequential decisions at each stimulus level, in a sequence which tends to converge on a selected target level.
