empirical CORRECT ANSWERS science is ________: based on data- we collect data
and then interpret it; we have to make sense of the behavior that we're trying to
understand
deterministic CORRECT ANSWERS science is __________: things obey physical laws;
not random in terms of cause and effect, and can draw generalizations from data that
we can extend on to other situations we have not yet experienced
predictive CORRECT ANSWERS science is ________: if a given phenomenon occurs,
it can influence another one; represents cause and effect relationships
parsimonious CORRECT ANSWERS science is _________: uses the simplest
explanation versus making it unnecessarily convoluted

acoustics CORRECT ANSWERS ____________ can help by telling us how the larynx
is operating or how articulators are moving; measures speech production through
microphone readings
kinematics CORRECT ANSWERS ______ is the study of speech movements

and resistances involved in regulating our breath stream as we speak
electromyography CORRECT ANSWERS __________ is the measure of electrical
activity in muscles as they are activated
speech perception CORRECT ANSWERS ________ __________ is how the brain

because our human perception of sound is nonlinear
intensity, IL, SPL CORRECT ANSWERS ___________ is the amplitude or 'size' of a
sound
