Developmental aspects of auditory and visual scanning.

60 Ss from Grades 1 through 6 were administered an auditory and visual scanning procedure and 27 of those Ss were given arithmetic and reading achievement tests. Data indicated scanning ability increases linearly with grade in school and the relationship between the scanning measures also increases sharply with grade. Auditory scanning was related to academic achievement; visual scanning only approached significance with arithmetic achievement but was unrelated to reading achievement.
