Praxis ETS SLP Test | Questions with 100% Correct Answers | Verified | Latest Update 2024

Which of the following is the major physical or organic factor underlying impairment in the speech of persons with cleft palate? (A) Congenital hearing loss from otitis media (B) Broad irregular maxillary arch (C) Palatopharyngeal insufficiency (D) Irregular vocal fold abduction - (C) is correct. Palatopharyngeal insufficiency or, more specifically, velopharyngeal insufficiency is the major cause of the hypernasal speech associated with cleft palate. (A), (B), and (C) are incorrect because otitis media is not congenital; in cleft palate, the maxillary arch is often collapsed and thus is narrow; and irregular vocal fold abduction is not associated with cleft palate. An SLP determines the mean length of utterance (MLU) of a language sample from a three-year-old child. Two weeks later, the SLP reevaluates the same sample and again determines the MLU. The extent to which the two scores are similar is most directly a function of the (A) validity of the scores (B) reliability of the scores (C) skewness of the score distribution
