Psychomotor Performance Effects Upon Elementary School Children by Sex and Perceptual Speed Ability of Three Compressions of an Instructional Sound Motion Picture.
Masterson, James; And Others
Forty-eight sixth-grade students were studied to determine their response to selected compressions of the narration of an instructional sound motion picture. A 4:10 color film with a 158 wpm recorded narration was shown at 25, 33-1/3 and 50 percent compression rates; performance time and quality were measured immediately and after 12-day intervals. It was found that compression of up to 50 percent did not significantly effect performance quality, but had a significantly negative effect on performance time in female students and those of low perceptual speed. Both sex and level of perceptual speed ability were held to be patent predictors of poorer quality and slower work in instruction via compressed sound motion pictures. A compression rate of 25 percent was held least effective for females and most effective for males; a 33-1/3 percent rate, least effective for those of low perceptual ability and most effective for those of high perceptual ability.
