Abstract
This study was designed to examine the effect of practice on lingual vibrotactile thresholds. Twenty Ss between the ages of 19 and 28 years were used in the experiment. Ten of the Ss were each given a 5-min orientation period before threshold readings were taken. The remainder also went rhrough a 5-min orientation period, but in addition received 30 min of practice. The practice group produced statistically significant lower and less variable thresholds than the nonpractice group at two of the three frequencies tested. These data indicate that familiarity with the instrumentation and required task is increased with prolonged practice, resulting in more precise threshold measurements.
