Stimulus picture identification in articulation testing

The present study was designed to compare the percent of correct initial identification of stimulus pictures on the Goldman-Fristoe Test of Articulation with the percent correct identification on the Arizona Articulation Proficiency Scale. This study was undertaken in an effort to clarify the results of a previous study in which the Goldman-Fristoe, a test designed to reduce time of administration, took significantly longer administration time than the Arizona, a traditional type of articulation test. Twenty normal-speaking and 20 articulation-defective children served as subjects for the study. Each subject was administered those portions of the articulation tests which included stimulus pictures used to elicit production of the consonants and consonant blends. Each child's initial identification of the stimulus picture was recorded. Results indicated that the Arizona test elicits significantly (p less than 0.001) more correct initial stimulus picture identifications thandoes the Goldman-Fristoe test.
