TY - JOUR AU - Taylor, D. W. AB - The article deals with learning to receive, learning to send, and measurement of aptitude. Some of the findings are: plateaus are not common in curves of learning to receive; the use of visual symbols should be avoided in teaching receiving; the initial speed at which individual characters are sent does not affect the speed with which men learn to receive; the negatively accelerated curve is typical of learning to send; each operator's sending may be identified on the basis of his individual style; the use of a special tape in teaching sending is no more efficient than having students send to one another; and achievement in code is not related to age, amount of previous education, prior vocation, or scholastic achievement. Correlations between code achievement and various parts of intelligence tests range from .08 to .42, while the correlation between code achievement and the Seashore musical tests is .56. The Signal Corps Code Aptitude Test has a reliability of .86 and a validity coefficient of .52. The Initial Learning Test, which measures the speed with which students learn the first eight characters, has a reliability of .97 and validity of .73.
