Tactual
Definition:
(a.) Of or pertaining to the sense, or the organs, of touch; derived from touch.
Example Sentences:
(1) When the distractor was an auditory arithmetic task, no difference emerged between the two hands for the retention of touches to the fingers; however, when the distractor was a tactual maze task executed by the right hand, asymmetry in favor of the left hand was observed.
(2) Results of the experiments indicated that aging is associated with decline in tactual discrimination ability.
(3) Errors in drawing the letters after tactual exposure and naming training showed that subjects had no accurate idea of the spatial relations or configuration of the dot patterns.
(4) A stepwise discriminant analysis procedure revealed an experimental form of the TMT (part X), Tactual Performance Test total time, and Tactual Performance Test localization to be the most sensitive measures.
(5) Experiments I and II showed no deficit in tactual perception nor in the inter-hemispheric transfer of tactual information.

(11) In most cases with these subjects, performance on simple detection and discrimination tasks showed facilitative effects with tactual vocoders.
(12) 14 reflective and 14 impulsive boys performed tactual matching tasks in which frequency of observation of the standard was manipulated by successive or simultaneous presentation and in which stimulus features were controlled so that the amount of stimulus analysis carried out might be inferred.
(13) The goal of the current study was to demonstrate improvements to speech reception through Tadoma through the use of supplementary tactual information, thus leading to a new standard of performance in the tactual domain.
