Studies in typewriter keyboard modification: II. Relationships between individual differences in performance on standard and modified typewriters

Abstract

Performed a series of correlational analyses to examine the relationship between typing speed and accuracy on the standard keyboard and on each of 6 modified keyboard configurations. 115 experienced standard-keyboard typists attending a university typing class were randomly assigned to 1 of 6 experimental groups. Ss received 2 hrs of typing practice on a modified keyboard interspersed between pre- and posttests on both the standard and modified typewriters. The correlations for measures of stroking speed and errors indicated that performance on the keyboards was generally significantly related with the higher correlation for the speed criterion. Also, performance on the posttest with the modified keyboard, an index of trainability, was best predicted by the sample of behavior observed on the pretest with the modified typewriter.
