Two experiments were performed to determine whether using the time saved by the time compression process to repeat or extend information presented by audio tapes would increase the amount learned by listening to rapid speech. Neither repeating nor extending information improved learning over that obtained by listening to uncompressed information for an equal amount of time. This was true for high and low mental aptitude subjects. The implication that more information can be learned in a unit of time with moderate compression remains to be substantiated.
