Abstract

In this study the writer served as both subject and experimenter. Previous to this experiment the writer had had 110 experience in punching Hollerith cards. The data used for punching were coded prior to the actual punching- of the cards. The 80-column card was used. There were sixteen 30-minute periods throughout a period of five weeks. With two unavoidable exceptions the practice periods were held each Monday, Wednesday, and Friday at 4:00 P.M.
