415 FINAL EXAM
1. A 4-year-old child produces the sentence "Daddy go store" but not "Daddy is
going to the store." This is most consistent with which stage of Brown’s stages of
morphological development?
A) Stage I
B) Stage II
C) Stage III
D) Stage IV
CORRECT ANSWER: A
Rationale: Brown’s Stage I is characterized by telegraphic speech (two- to three-
word utterances) lacking most grammatical morphemes such as present progressive
"-in" and auxiliary "is." Stage II introduces "-in," past tense, and prepositions,
which are absent here.
2. Which of the following is the strongest predictor of later reading comprehension
in typically developing children?
A) Articulation accuracy at age 3
B) Phonological awareness at age 5
C) Number of vocabulary words produced at age 2
D) Fluency of rapid naming of colors at age 6
CORRECT ANSWER: B
Rationale: Phonological awareness (e.g., rhyming, segmenting) at kindergarten age
is the most robust predictor of early decoding and later reading comprehension.
Vocabulary size is important but less predictive than phonemic awareness for
decoding-based comprehension.
3. A clinician assesses a child with suspected childhood apraxia of speech (CAS).
Which feature is most discriminative of CAS compared to other speech sound
disorders?
A) Consistent errors across multiple trials
B) Vowel distortions
C) High frequency of final consonant deletion
D) Abnormal rate and rhythm of speech with groping
,CORRECT ANSWER: D
Rationale: CAS is characterized by prosodic abnormalities, slow rate, and
visible/audible groping for articulatory postures. Vowel distortions can occur, but
groping and rhythm disturbances are more specific markers.
4. During a language sample, a 30-month-old produces "more cookie" and "want
juice." These utterances primarily demonstrate which pragmatic function?
A) Commenting
B) Requesting
C) Protesting
D) Greeting
CORRECT ANSWER: B
Rationale: The child is requesting objects (cookie, juice) using a two-word
combination. Commenting would be "cookie good," protesting would be "no
cookie," and greeting is not relevant.
5. A 7-year-old with normal peripheral hearing fails to understand ambiguous
sentences and jokes, takes language literally, and has difficulty with narrative
coherence. This profile most suggests:
A) Specific language impairment (SLI) – phonological subtype
B) Autism spectrum disorder (ASD) – pragmatic language impairment
C) Conductive hearing loss
D) Apraxia of speech
CORRECT ANSWER: B
Rationale: Difficulty with nonliteral language (ambiguity, jokes), literal
interpretation, and narrative coherence are hallmark pragmatic deficits. Combined
with normal hearing, this strongly points to ASD or a pragmatic language disorder.
6. Which developmental milestone typically emerges FIRST?
A) Using "no" to refuse
B) Pointing to request (proto-imperative)
C) Producing canonical babbling (/baobab/)
D) Following a two-step command
CORRECT ANSWER: C
Rationale: Canonical babbling emerges around 6–9 months. Proto-imperative
pointing appears around 10–12 months, "no" refusal by 12–15 months, and two-
step commands by 24–30 months.
, 7. In the assessment of bilingual children, which practice is most appropriate?
A) Assess only in English to ensure school readiness
B) Assess in both languages and use dynamic assessment
C) Translate a standardized English test into the home language
D) Delay assessment until the child is English-dominant
CORRECT ANSWER: B
Rationale: Best practice requires assessing in both languages to differentiate
difference from disorder. Dynamic assessment (test-teach-retest) is recommended
to reduce cultural/linguistic bias. Translation of tests invalidates norms.
8. A 5-year-old says "I runner home" instead of "ran home." This error pattern is
best described as:
A) Over regularization
B) Under extension
C) Omission of past tense
D) Phonological process of fronting
CORRECT ANSWER: A
Rationale: Over regularization applies regular past tense "-end" to irregular verbs
(rumrunner). It indicates knowledge of a rule but not exceptions, typical of
preschool-aged children.
9. Which type of tongue thrust swallow is most likely to cause a persistent
interdental lisp beyond age 6?
A) Normal infantile swallow
B) Simple anterior tongue thrust
C) Complex tongue thrust with lateral spread
D) Posterior tongue thrust
CORRECT ANSWER: B
Rationale: Simple anterior tongue thrust involves forward tongue placement during
swallowing and speech, maintaining an interdental position for /s, z/, causing a
lisp. Infantile swallow resolves by age 6; complex patterns involve additional
movements.
10. A 50-year-old presents with fluent, empty speech, impaired repetition, and
relatively preserved comprehension. The most likely diagnosis is:
A) Boca’s aphasia
B) Wernicke’s aphasia
