Points of Subjective Equality (PSE) are commonly measured using staircase or constant
stimuli methods. However, the staircase method is highly dependent on the step size, and …

In experiments that measure a point of subjective equality, it is necessary to employ a
psychophysical technique that measures the 50% point (P50) on the psychometric function …

Several elaborate procedures have been recommended and used for computing the
threshold value from data obtained by the constant method. But very few of them can be …

In studying perception, psychologists must sometimes estimate perceivers' difference
thresholds and points of subjective equality (PSEs). To quickly estimate a threshold, one …

In psychophysics, the point of subject equality (PSE) is any of the points along a stimulus
dimension at which a variable stimulus (visual, tactile, auditory, and so on) is judged by an …

One of the most precise methods to establish psychometric functions and estimate threshold
and slope parameters is the constant stimuli procedure. The large distribution of …

Introduction: Estimating psychometric thresholds can be challenging, especially
stereoacuities (Chopin et al., 2019). Adaptive methods used for estimation generally assume …

Knowledge of an observer's psychometric function slope is potentially useful in clinical
visual psychophysics (for example, perimetry), however, the short test times necessary in a …

Introduction: Psychophysical methods are used in clinical settings to obtain estimates of
visual performance. Such methods should be fast and accurate, yet robust to the corrupting …

From the proportion matrix obtained by the method of paired comparisons, a mean point of
subjective equality (PSE) may be computed for each stimulus. The almost linear function that …
