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

Threshold and channel interaction in cochlear implant users: evaluation of the tripolar electrode configuration.
TL;DR: The data suggest that tripolar channels with high thresholds may reveal cochlear regions of low neuron survival or poor electrode placement, and are correlated with channel-to-channel variability in tripolar threshold.

Neural correlates of subjective awareness and unconscious processing: An erp study
TL;DR: The results indicate that liminal stimuli that do not affect performance undergo considerable processing and that subjective awareness is associated with a late wave of activation with widely distributed topography.

Sensitivity to modulations of luminance and contrast in visual white noise: separate mechanisms with similar behaviour.
TL;DR: It is concluded that a single mechanism sensitive to both LM and CM cannot predict the pattern of results for mixtures, while a model containing separate pathways for LM andCM, followed by energy summation, does so successfully and is quantitatively consistent with the finding of order-specific facilitation.

Changes in pitch with a cochlear implant over time
TL;DR: It is shown that electric pitch perception often shifts in frequency, sometimes by as much as two octaves, during the first few years of implant use, which raises questions for strict place-based theories of pitch perception, and implies that experience may have a greater influence on cochlear implant perception than previously thought.

Auditory Processing Deficits in Dyslexia: Task or Stimulus Related?
TL;DR: The degree of impairment was dependent on task rather than stimulus complexity, which suggests that dyslexics with additional learning difficulties (D-LDs) suffer from a similar type of deficits when processing speech and nonspeech sounds.

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.
