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

Temporal contrast sensitivity during smooth pursuit eye movements.
TL;DR: Results show that contrast sensitivity was mainly determined by retinal-image motion but was slightly reduced during smooth pursuit eye movements, and sensitivity for motion opposite to pursuit direction was reduced in comparison to motion in pursuit direction.

Spectrotemporal modulation sensitivity for hearing-impaired listeners: Dependence on carrier center frequency and the relationship to speech intelligibility
TL;DR: Poor speech understanding in noise by hearing-impaired (HI) listeners is only partly explained by elevated audiometric thresholds, and poor speech-reception and STM-detection performance for HI listeners may be related to a combination of reduced frequency selectivity and a TFS-processing deficit limiting the ability to track spectral-peak movements.

Higher level chromatic mechanisms for image segmentation.
TL;DR: An important role for multiple, broadly tuned mechanisms in image segmentation is suggested, with measured tuning widths critically depended on the type of noise: Noise modulated along one direction results in narrow tuning, whereas two-sided noise results in broad tuning.

Toward a unified theory of voice production and perception
TL;DR: Development of an integrated model of voice linking production and perception should be a priority for scientists interested in voice to explain what physical condition(s) might underlie a given voice quality, or what voice quality might result from a specific physical configuration.

Vowel formant discrimination: Towards more ordinary listening conditions
Diane Kewley-Port,Yijian Zheng +1 more
TL;DR: The purpose of the present study was to change the listening procedures in several substantial ways from optimal towards more ordinary listening conditions, including a higher level of stimulus uncertainty, increased levels of phonetic context, and with the addition of a sentence identification task.

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.
