(Exam Weight: ~33⅓% | 34 Questions)
Category 1 Tasks Covered: Basic human communication processes • Anatomy
and physiology of speech and hearing • Neuroanatomy • Acoustics and phonetics •
Language acquisition and development • Learning theory • Multicultural
awareness • Ethics and professional issues • Research design and psychometrics •
Evidence-based practice • Scope of practice
Question 1. Which cranial nerve is responsible for taste sensation from the anterior
two-thirds of the tongue?
A) Glossopharyngeal (CN IX)
B) Facial (CN VII)
C) Trigeminal (CN V)
D) Hypoglossal (CN XII)
Rationale: The facial nerve (CN VII) via the chorda tympani branch carries taste
sensation from the anterior two-thirds of the tongue. The glossopharyngeal nerve
(A) provides taste from the posterior one-third. The trigeminal nerve (C) provides
general sensation to the tongue. The hypoglossal nerve (D) provides motor
innervation to the tongue.
Question 2. Which muscle is the primary abductor of the vocal folds?
A) Thyroarytenoid
B) Lateral cricoarytenoid
,C) Posterior cricoarytenoid
D) Transverse arytenoid
Rationale: The posterior cricoarytenoid is the only intrinsic laryngeal muscle that
abducts (opens) the vocal folds. The thyroarytenoid (A) is the primary adductor
and tensor. The lateral cricoarytenoid (B) is an adductor. The transverse arytenoid
(D) is an adductor.
Question 3. Which structure forms the lower boundary of the nasopharynx?
A) Soft palate
B) Level of the hard palate
C) Epiglottis
D) Hyoid bone
Rationale: The nasopharynx extends from the posterior nasal choanae to the level
of the soft palate (which forms its floor). The soft palate (A) is the mobile posterior
portion of the palate. The epiglottis (C) is in the laryngopharynx. The hyoid bone
(D) is in the anterior neck.
Question 4. At what age does a typically developing child produce all vowel
sounds correctly?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Rationale: Vowel sounds are among the earliest developing speech sounds and are
typically mastered by age 3. Consonant mastery continues through age 7–8 for
later-developing sounds such as /r/, /s/, and /θ/.
Question 5. Brown's morphemes are used to measure:
A) Phonological awareness
B) Grammatical morpheme development
C) Vocabulary size
D) Pragmatic skills
Rationale: Brown's 14 grammatical morphemes (e.g., present progressive -ing,
plural -s, past tense -ed) are used to assess morphosyntactic development in
,children. They are ordered by typical acquisition sequence and are a key measure
of language development.
Question 6. According to Piaget, which stage of cognitive development is
characterized by egocentric thinking and the emergence of symbolic play?
A) Sensorimotor
B) Preoperational
C) Concrete operational
D) Formal operational
Rationale: The preoperational stage (approximately ages 2–7) is characterized by
egocentrism, symbolic play, and intuitive thought. The sensorimotor stage (A) is
birth to 2 years. The concrete operational stage (C) is ages 7–11. The formal
operational stage (D) is ages 11+.
Question 7. Which of the following is an example of a dialectal difference rather
than a disorder?
A) A 4-year-old who omits final consonants
B) An adult who says "ax" instead of "ask"
C) A 6-year-old who cannot produce /r/
D) An adult with apraxia of speech
Rationale: Saying "ax" instead of "ask" is a dialectal variation common in some
African American English and Southern American English dialects. It is not a
disorder. Option A represents a phonological process. Option C represents a speech
sound disorder. Option D is a motor speech disorder.
Question 8. Which of the following best describes the principle of "least restrictive
environment" (LRE) under IDEA?
A) Students with disabilities must be educated in separate classrooms
B) Students with disabilities should be educated with non-disabled peers to the
maximum extent appropriate
C) Students with disabilities must receive all services in a clinical setting
D) Students with disabilities cannot participate in general education
Rationale: LRE requires that students with disabilities be educated alongside their
typically developing peers to the greatest extent appropriate, with removal only
when the nature or severity of the disability prevents satisfactory education in
general classes even with supplementary aids.
, Question 9. Which research design provides the highest level of evidence for
establishing cause-and-effect relationships?
A) Case study
B) Randomized controlled trial (RCT)
C) Correlational study
D) Expert opinion
Rationale: RCTs provide the highest level of evidence because randomization
controls for confounding variables. Case studies (A) and expert opinion (D) are
lower levels of evidence. Correlational studies (C) cannot establish causation.
Question 10. Which of the following is a core ethical principle in the ASHA Code
of Ethics?
A) Informed consent
B) Avoiding all conflict
C) Prioritizing personal gain
D) Limiting services to adults
Rationale: Informed consent is a fundamental ethical principle requiring that
clients understand and voluntarily agree to services. The ASHA Code of Ethics
also emphasizes beneficence, nonmaleficence, justice, and fidelity.
Question 11. Which acoustic property of speech refers to the frequency of vocal
fold vibration?
A) Intensity
B) Fundamental frequency
C) Formant frequency
D) Harmonics-to-noise ratio
Rationale: Fundamental frequency (F0) is the rate of vocal fold vibration,
perceived as pitch. Intensity (A) is perceived as loudness. Formant frequency (C)
relates to vocal tract resonances. Harmonics-to-noise ratio (D) measures voice
quality.
Question 12. Which of the following is an example of a standardized, norm-
referenced assessment?
A) Language sample analysis
B) Peabody Picture Vocabulary Test (PPVT)
