TL;DR: Psychophysical measures of threshold sensitivity, temporal gap detection, temporal order identification, and temporal masking have been obtained, in hearing, vision, and touch, and suggest that the long-standing observation of age-related changes in cognitive function may be mediated by age- related changes in global sensory processing.

TL;DR: It is demonstrated that three physical quantities, vibratory power, compliance, and friction carry roughness, hardness, and stickiness information, predicting perceived dissimilarity of texture pairs with indirect touch.

TL;DR: The similarity in the representations of orientation in the visual and somatosensory systems suggests that analogous neural mechanisms mediate early visual and tactile form processing.

TL;DR: The two-point threshold, or compass test, has been used as a measure of tactile spatial resolution; however, since it was first developed, there have been problems associated with its use as discussed by the authors, such as setting an appropriate criterion for responding "two, extreme variability both within and between subjects, and the ability of subjects to discriminate two points from one at separations well below the twopoint threshold.

TL;DR: Correlational and principalcomponents factor analyses performed on the data from the 137 older adults were generally consistent with task and modality independence of the psychophysical measures.
