Abstract
Three parameters of tactile resolution (area, force, and pressure of stimulation) were investigated in three experiments. A two-point discrimination task was presented by means of an electromechanical stimulator permitting precise control of all relevant stimulus variables. The results indicated a positive linear effect of area, a curvilinear effect of force, and no effect of pressure on the threshold for resolution of two tactile stimuli. The findings are in agreement with data on the influence of the same parameters in visual resolution.
