Visual Recognitive Thresholds Following Sensory Deprivation

The American Journal of Psychology, 1959
Recent studies of sensory deprivation have shown that reduced stimulus-variability may appreciably modify sensory and cognitive efficiency. The McGill experiments demonstrated that exposing human Ss for several days to an environment, which minimized stimulus-change and restricted visual functions to the perception of diffuse light, resulted in ...

Variability of sensory threshold determination in clinical use

Journal of the Neurological Sciences, 1981
The variability of perception threshold determination for vibration, tactile stimuli and thermal stimuli, with instruments intended for clinical use, was studied in 13 healthy subjects and 27 patients with chronic polyneuropathy. Normal thresholds for tactile and thermal stimuli were determined in 51 healthy subjects.

Cross-modal Induction of Changes in Sensory Thresholds

Quarterly Journal of Experimental Psychology, 1968
Two experiments are reported in which subliminal stimulation of one modality with emotional material impairs detection performance in a different modality. In the first experiment the visual awareness threshold for neutral material was raised by simultaneous auditory presentation of emotional words.

Sensory retraining following orthognathic surgery: effect on threshold measures of sensory function

Journal of Oral Rehabilitation, 2009
Summary  The purpose of this analysis was to examine the effect of sensory retraining on sensory function after bilateral sagittal split osteotomy (BSSO). A total of 186 subjects were enrolled in a multi‐centre double‐blind two parallel group stratified block randomized clinical trial.

Aging and quantitative sensory thresholds.

Electromyography and clinical neurophysiology, 1990
Cutaneous thresholds for vibration and thermal sensitivity were quantitated at the index finger and great toe in 54 subjects without obvious neurological disease. Twelve patients over sixty years of age also consented to standard nerve conduction studies which proved normal.

Quantifying supra-threshold sensory deficits in listeners with normal hearing thresholds

The Journal of the Acoustical Society of America, 2014
There is growing suspicion that some listeners with normal-hearing thresholds may be suffering from a specific form of sensory deficit—a loss of afferent auditory nerve fibers. We believe such deficits manifest behaviorally in conditions where perception depends upon precise spectro-temporal coding of supra-threshold sound. In our lab, we find striking

Thresholds for Fufu Sensory Properties

Fufu, a staple food in West Africa, is highly valued for its texture, flavor, and color—attributes that significantly influence consumer acceptability. This study aimed to determine the threshold levels of key fufu sensory attributes using a combination of Quantitative Descriptive Analysis (QDA), instrumental texture and color measurements, and ...

Apparent Fluctuations of a Sensory Threshold

Quarterly Journal of Experimental Psychology, 1955
An account is given of a method for the nearly continuous recording of sensory thresholds and other psycho-physical variables. Its application to the difference-threshold for sound-intensity is described. It is found that this threshold, so recorded, shows irregular fluctuations in time, excursions of up to 100 per cent, being commonly present.

Efficient estimation of sensory thresholds with ML-PEST

Spatial Vision, 1997
A set of C and C+2 routines are described that allow the efficient estimation of sensory thresholds in psychophysical experiments using a maximum-likelihood staircase procedure. They have been used effectively in visual, auditory, gustatory, and olfactory psychophysics.
