SHS 301 Final Exam | Complete Practice Questions, Correct
Answers & Detailed Rationales (2026/2027)
Question 1
Which nonlinear dynamic measure of voice analysis quantifies the
degree of determinism or predictability of a time-series signal in phase
space, often used to assess chaotic vocal fold vibration in pathological
voices?
A. Jitter percentage
B. Harmonic-to-Noise Ratio (HNR)
C. Correlation dimension / Recurrence Quantification Analysis (RQA)
D. First formant frequency (𝐹1 )
Correct Answer: C. Correlation dimension / Recurrence Quantification
Analysis (RQA)
Detailed Rationale: Nonlinear dynamic measures such as correlation
dimension and recurrence quantification analysis evaluate complex,
chaotic, or irregular vocal fold oscillations that traditional perturbation
metrics (like jitter and shimmer) fail to capture adequately.
Question 2
What advanced instrumentation uses small receiver coils attached to
articulators (lips, tongue, jaw) in conjunction with an alternating
magnetic field to track real-time kinematic speech movements in three
dimensions?
A. Videostroboscopy
,B. Electromagnetic Articulography (EMA)
C. Electropalatography (EPG)
D. Pneumotachograph
Correct Answer: B. Electromagnetic Articulography (EMA)
Detailed Rationale: EMA records high-precision spatial and temporal
movement trajectories of speech articulators using magnetic fields to
track miniature sensor coils.
Question 3
What is the primary function of the superior olivary complex (SOC) in
the central auditory nervous system?
A. Processing high-frequency visual inputs
B. Performing primary binaural processing, including the computation
of interaural time differences (ITD) and interaural level differences (ILD)
for sound localization.
C. Secreting cerumen into the external auditory meatus
D. Controlling middle ear impedance matching via ossicular rotation
Correct Answer: B. Performing primary binaural processing, including
the computation of interaural time differences (ITD) and interaural level
differences (ILD) for sound localization.
Detailed Rationale: The SOC is the lowest level in the auditory
brainstem where neural information from both ears converges, making
it crucial for sound localization and lateralization.
Question 4
,According to Rayleigh's Duplex Theory of sound localization, what
acoustic cues are utilized for localizing high-frequency sounds versus
low-frequency sounds?
A. High-frequency sounds rely primarily on interaural level differences
(ILD), whereas low-frequency sounds rely on interaural time differences
(ITD).
B. High-frequency sounds rely entirely on visual input; low-frequency
sounds rely on tactile sensation.
C. Both high and low frequencies rely exclusively on pinna spectral cues.
D. High-frequency sounds use fundamental frequency contour
matching.
Correct Answer: A. High-frequency sounds rely primarily on interaural
level differences (ILD), whereas low-frequency sounds rely on interaural
time differences (ITD).
Detailed Rationale: Head shadow effects create significant level
differences for high frequencies (short wavelengths), while wave
diffraction allows low frequencies to wrap around the head, requiring
phase/time difference processing.
Question 5
Which transcortical aphasia syndrome is characterized by severely
impaired auditory comprehension and spontaneous speech, but with
preserved repetition (echolalia) and fluent verbal output?
A. Transcortical motor aphasia
B. Transcortical sensory aphasia
, C. Conduction aphasia
D. Global aphasia
Correct Answer: B. Transcortical sensory aphasia
Detailed Rationale: Transcortical sensory aphasia involves isolation of
the speech repetition pathway (arcuate fasciculus) from damaged
temporal-parietal association areas, resulting in fluent repetition
despite poor comprehension.
Question 6
What neurogenic communication disorder involves fluent, well-
articulated speech with intact comprehension, but profound deficits in
repeating heard speech due to suspected damage to the arcuate
fasciculus?
A. Broca's aphasia
B. Conduction aphasia
C. Subcortical aphasia
D. Anomic aphasia
Correct Answer: B. Conduction aphasia
Detailed Rationale: Conduction aphasia classically features
disproportionate repetition deficits and phonemic paraphasias due to
disconnection between Wernicke's and Broca's areas.
Question 7
During the pharyngeal phase of swallowing, which group of muscles
actively contracts to elevate and pull the hyolaryngeal complex
anteriorly and superiorly?
