ComD 5070 Exam 1 Study Guide modules 1-5• what is science?4 features of the scientific method - correct answer 1) EMPIRICAL - based on data 2) DETERMINISTIC - obeys physical laws 3) PREDICTIVE - if you this....then that will happen 4) PARSIMONIOUS - use the simplest explanation poss. • SLPs' use of technology [why do we use it clinically? how can acoustics help?] - correct answer - OVERCOME LISTENER BIAS. Consistent, reliable measurement is provided by analysis. - Use OBJECTIVE TERMS AND MEASURES TO DESCRIBE THE SEVERITY of a disorder objectively. We can standardize our measurements of speech since we have objective criteria to measure each patient against. - TRACK PROGRESS over time, and DEMONSTRATE TREATMENT EFFICIENCY. - EBP (Evidence Based Practice). We measure the client's performance before and after therapy in order to objectively prove that the treatment was effective. - PROVIDE BIOFEEDBACK to the client. Show the person what they are doing on a computer display in real time, and can help them change behavior. How can acoustics help in the SLPs use of technology? - correct answer 1) ACOUSTIC PHONETICS- measuring of speech production through MICROPHONE RECORDINGS and studying what it can tell us about the way the larynx is operating or the articulators are moving. 2) PHYSIOLOGOCAL PHONETICS - • KINEMATICS - study of SPEECH MOVEMENTS • AERODYNAMICS - PRESSURE, FLOW and RESISTANCE we use to regulate our breath stream as we speak. • ELECTROMYOGRAPHY - the ELECTRICAL ACTIVITY OF MUSCLES as they are activated 3) SPEECH PERCEPTION - the aspects of signal processing of the brain. We will DRAW PARALELLS FROM the PERCEPTUAL ASPECTS of speech understanding and the ACOUSTICAL TECHNIQUES that we use to evaluate a speech signal in a quantitative way.
