Comprehension of Repeated Time-Compressed Recordings

Time-compressed, tape recorded messages were used to determine if listening to the message twice, in the same amount of time required to listen to the uncompressed message once, would improve listening com prehension scores of high and low aptitude men. The results indicated that for both groups of subjects, listen ing to the compressed messages twice improved comprehension scores over scores obtained by listening to the compressed tapes once. Comprehension of repeated time compressed messages was not improved over that obtained by a single listening to the uncompressed messages.
