Adaptive psychophysical procedures
Improvements in measuring thresholds, or points on a psychometric function, have advanced the field of psychophysics in the last 30 years. The arrival of laboratory computers allowed the introduction of adaptive procedures, where the presentation of the next stimulus depends on previous responses of the subject. Unfortunately, these procedures present themselves in a bewildering variety, though...

15 صفحه اولPsychophysical models of masking for coding applications
In this article we apply signal detection theory to qualitatively unify the intensity justnoticable difference (JND) and masking data of Wegel and Lane (1924), Fletcher and Munson (1933 – 1938), Miller (1947), and Egan and Hake (1950). We do this by treating the loudness as the first moment, and the intensity JND as the second moment, of the random variable we call the single-trial loudness. Fr...
متن کامل[Comparison of vibrotactile thresholds in women obtained with two psychophysical measurement methods].
BACKGROUND The aim of the study was to determine differences between vibrotactile thresholds values in healthy women obtained with two psychophysical methods: the method drafted in ISO standard ISO 13091-1:2001 and the method hitherto used in Poland. MATERIAL AND METHODS Twenty two women (mean age, 37.9 +/- 9.7 years) participated in the study. Vibrotactile perception thresholds were measured...
متن کاملDependence of vibrotactile thresholds on the psychophysical measurement method.
OBJECTIVES To investigate the dependence of vibrotactile thresholds on the psychophysical method used in the diagnosis of neurological dysfunction caused by exposure to hand-transmitted vibration. To compare thresholds obtained with (a) 'continuously variable' versus intermittent 'staircase' stimulation using 'yes-no' responses, and (b) 'yes-no' and 'forced-choice' responses using intermittent ...
