Temporal factors in tactile spatial acuity: evidence for RA interference in fine spatial processing.
We investigated the extent to which subjects' ability to perceive the fine spatial structure of a stimulus depends on its temporal properties (namely the frequency at which it vibrates). Subjects were presented with static or vibrating gratings that varied in spatial period (1-8 mm) and vibratory frequency (5-80 Hz) and judged the orientation of the gratings, presented either parallel or perpen...
متن کاملTactile Spatial Acuity from Childhood into Adulthood
Measurement of human tactile spatial acuity – the ability to perceive the fine spatial structure of surfaces contacting our fingertips – provides a valuable tool for probing both the peripheral and central nervous system. However, measures of tactile spatial acuity have long been plagued by a prodigious amount of variability present between individuals in their sense of touch. Previously propos...
متن کاملTactile Acuity Charts: A Reliable Measure of Spatial Acuity
For assessing tactile spatial resolution it has recently been recommended to use tactile acuity charts which follow the design principles of the Snellen letter charts for visual acuity and involve active touch. However, it is currently unknown whether acuity thresholds obtained with this newly developed psychophysical procedure are in accordance with established measures of tactile acuity that ...
متن کاملSpatial-Temporal Trend Modeling for Ozone Concentration in Tehran City
Fitting a suitable covariance function for the correlation structure of spatial-temporal data requires de-trending the data. In this article, some potential models for spatial-temporal trend are presented. Eventually the best model will be announced for de-trending tropospheric ozone concentration data for the city of Tehran (Capital city of Iran). By using the selected trend model, some ...
متن کاملTactile spatial acuity enhancement in blindness: evidence for experience-dependent mechanisms.
Tactile spatial acuity is enhanced in blindness, according to several studies, but the cause of this enhancement has been controversial. Two competing hypotheses are the tactile experience hypothesis (reliance on the sense of touch drives tactile-acuity enhancement) and the visual deprivation hypothesis (the absence of vision itself drives tactile-acuity enhancement). Here, we performed experim...
