Abstract
Effect of laterality on absolute judgments of the number of successive tactile pulses was investigated by presenting 5 to 13 mechanical pulses to the preferred and nonpreferred hands of right- and left-handed subjects. While nonpreferred hand stimulation consistently yielded significantly higher reports of signal number for both right- and left-handed subjects, there was a shift in laterality in terms of response accuracy. Preferred hand reports for both right- and left-handed subjects were more accurate with trains of seven or fewer pulses but less accurate when trains contained more than seven pulses.
