Speech sound production testing was based upon the Goldman-Fristoe Test
of Articulation, Second Edition (GFTA-2, Goldman & Fristoe, 2000). This test was
normed on persons ages two through 21. Sighted children take this test by looking
at a picture and spontaneously naming what a picture or answering a simple
question about the item shown. Children's responses are generally one-word or
short phrases or sentences, and only production of the target word is scored. For
example, if the child, when shown a picture of a house, says the word "house,"
production of the /h/ sound can be evaluated. The visual cue allows the child to
speak the word without hearing the examiner say the word first. The GFTA-2
administration guidelines have specific prompts to use if an examinee does not
produce a target response spontaneously.
