COMD 5070 Exam 1 Study Guide


1. What are the four features of the scientific method?

✔️ Empirical

✔️ Deterministic

✔️ Predictive

✔️ Parsimonious



2. What does empirical mean?

✔️ Based on data

(This indicates that findings are derived from observation or experiment rather than theory or pure
logic.)



3. What does deterministic mean?

✔️ Obey physical laws

(This means that the behavior of the system can be precisely predicted based on initial conditions and
governing laws.)



4. What does predictive mean?

✔️ Show what will happen

(This feature emphasizes that the method should be able to generate predictions that can be tested.)



5. What does parsimonious mean?

✔️ Use the simplest explanation possible

(This principle advocates for simplicity in explanations until complexity is warranted.)



6. Why do SLPs use technology in clinical practices?

✔️ To overcome listener bias

, ✔️ To describe severity objectively

✔️ To demonstrate treatment efficacy (track progress)

✔️ To provide biofeedback



7. What is the difference between pitch perception and frequency measurement?

✔️ Pitch is subjective to the listener; frequency is objective and can be measured

(Pitch perception can vary among individuals, while frequency corresponds to measurable physical
properties.)



8. How do waveforms differ as frequency goes up or down?

✔️ Higher frequency wavelengths appear closer together with more cycles over a period of time than
lower frequencies

(This means that higher frequencies result in more oscillations within a fixed time frame.)



9. What is the difference between loudness perception and intensity measurement?

✔️ Loudness is subjective and cannot be measured; intensity is objective and can be measured by
equipment

(Loudness is how we perceive sound while intensity is a physical measure of sound power.)



10. What are the units of measurement for intensity?

✔️ HL (Hearing Level)

✔️ SPL (Sound Pressure Level)



11. What is difference limens?

✔️ The smallest detectable change (DL)

(This refers to the smallest difference in a stimulus that can be detected.)



12. What is the difference limens for frequency?

✔️ DLs become larger as the frequency decreases
