Studies in International Morse Code. III. The efficiency of the code as related to errors made during learning

Abstract

Learning reception of the Morse code is here treated as a problem in discrimination, the errors made being considered primarily as examples of stimulus generalization. Less generalization takes place in shorter signals, while more is encountered in pure dot than in pure dash or mixed-component signals. The dotting error is found to be especially resistive to remedial work and usually indicates unsatisfactory progress. Revisions of the code in respect to three signals are suggested as a possible answer to the dotting error and other difficulties of beginners. (See 18: 294; 1658.)
