The experiment was designed to investigate the effects of 1 knowledge of test vocabulary and 2 practice in responding to spondee words at threshold intensities on the spondee threshold in normal-hearing subjects. Results of this experiment were 1 practice in responding to spondee words at threshold intensities does not influence the spondee threshold in normal-hearing subjects, and 2 normal-hearing subjects given prior knowledge of the test vocabulary yield spondee thresholds 4 to 5 db lower than those yielded by subjects not given such knowledge.
