4 features of the scientific method - Correct Answer-1)
Science is empirical- we collect data and interpret it
(based on data)
2) Science is Deterministic - Things are not random.
Because of cause and effect, we can draw generalizations
from the data that we have and extrapolate
3) Science is predictive - if you do this, then that will
happen.
4) Science is parsimonious - use the simplest explanation
possible, try to describe things in economical terms so we
can understand it. Use the simplest terms possible, but no
simpler.
Why do SLPs use technology - Correct Answer-1) Overcome
listener bias - computer isn't influenced by what it has
heard before. It is a consistent, reliable measure.
2) Describe severity objectively - standardizes measures of
speech
, 3) Track progress over time - helps demonstrate treatment
efficacy
4) Helps to comply with ASHA's focus on EBP - provides
hard data to measure rather than just gut feelings about
progress based on experience.
5) Biofeedback- computer display in real time - ex:
visipitch shows intonations on screen in real time, shows
them progress as they speak, better than playing back a
recording.
How can acoustics help? - Correct Answer-acoustics can
tell us a lot about what is going on that can't be seen.
Acoustics is a way of using quantitative measures to to
describe a physical phenomenon, rather than relying on
our human impressions
Frequency - Correct Answer-how frequently a waveform
repeats. Measured in Hz (cycles per second). Within the
same window length, a higher frequency sound wave will
show more repetitions than a lower frequency sound wave
simplest sound - Correct Answer-pure tone (sine wave)
Pitch - Correct Answer-the subjective measure of
frequency; you cannot measure pitch with an instrument.
You can have people match pitch perception to
frequencies.
Intensity - Correct Answer-amplitude or size of a
sound.Adjusting volume, is adjusting the physical intensity
of sound.
