It may be confidently stated, as a result of the research of the past five years, that all children of average or better than average general intelligence are capable of literacy; and that very early use of and interest in reading are strongly symptomatic of general superiority in selective thinking. From these facts we may hark back to the conclusion of the physiological psychologists, Ladd and Woodworth: “Indeed, the entire cerebrum would seem to be, of necessity, involved in man’s linguistic attainments and uses.” Mastery of language is, as Binet concluded, one of the most reliable indications of competence in general.
