A Comparative Study of Articulation Acquisition as Based on a Study of 240 Normals, Aged Three to Six

    Results of an exploratory study on articulation showed that children were acquiring proficiency in articulatory skills at an earlier age than would be expected from previously established norms. These results indicate a need for new normative data consistent with the performance of children seen at the present time. The articulatory skills of 240 children, ranging in age from three to six years, were evaluated by the screening test of articulation developed as a subtest of a newly developed instrument, the Illinois Children’s Language Assessment Test. The measure was designed to test more than one sound per word with the child repeating the word after the examiner. The norms obtained from this investigation were compared with previously established norms of articulation. Results indicate that 43% of the sounds tested were produced correctly from six months to four and one-half years earlier than would be expected from previously established norms.
