TLDR
A broad class of up‐down methods used in psychoacoustics with due emphasis on the related problems of parameter estimation and the efficient placing of observations is described, including examples where conventional techniques are inapplicable.Abstract:
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

Measures of working memory, sequence learning, and speech recognition in the elderly.
Larry E. Humes,Shari S. Floyd +1 more
TL;DR: This study describes the measurement of 2 cognitive functions, working-memory capacity and sequence learning, in 2 groups of listeners: young adults with normal hearing and elderly adults with impaired hearing, with a unique, nonverbal technique patterned after the Simon memory game.

"Central" auditory gap detection: A spatial case
TL;DR: Normal listeners were tested for their temporal auditory gap detection thresholds using free-field presentation of white-noise stimuli delivered from the left (L) and right (R) poles of the interaural axis, suggesting that this timing process can operate on perceptual channels emerging from central nervous system processing.

Detecting dead regions using psychophysical tuning curves: A comparison of simultaneous and forward masking
Karolina Kluk,Brian C. J. Moore +1 more
TL;DR: The edge frequencies, fe, of DRs estimated using four methods were compared using the TEN(HL) test; psychophysical tuning curves (PTCs) measured in simultaneous masking using a ‘fast’ method (sweeping masker) and a “classical” method; and PTCs measured in forward masking (sinusoidal masker), which were similar and were usually close to, but somewhat above, the values of fe.

Binaural Advantage for Younger and Older Adults with Normal Hearing.
TL;DR: Binaural processing of sentences revealed some age-related deficits in the use of interaural difference cues, whereas no deficits were observed for more simple detection or recognition tasks.

Auditory sensory memory in schizophrenia: inadequate trace formation?
TL;DR: Behavioural and electrophysiological results indicate intact temporal processing of filled intervals and equal temporal resolution limits in schizophrenia, but both ERP measures indicated differences in auditory processing that may be traced to activity occurring during the first 250 ms.

The staircrase-method in psychophysics.
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.
