Question

Sherry had throat surgery and could not talk for days. She worked with a speech therapist to increase her voice loudness. The therapist used an instrument to measure increases in the loudness of her voice. What dimension of behavior was the speech therapist recording?

a) Topography

b) Intensity

c) Duration

d) Frequency

Answer 1

The speech therapist was recording the intensity of Sherry's voice, which relates to loudness and is measured in decibels. Intensity indicates the amplitude and power of the sound wave.

Step-by-step explanation:

The dimension of behavior that the speech therapist was recording as part of Sherry's recovery after throat surgery is intensity. This is because the therapist used an instrument to measure the increases in the loudness of her voice. Loudness, which directly correlates to intensity, is the perception of the strength or weakness of a sound wave and is usually measured in decibels.

When referring to speech and voice, the intensity level is a vital attribute that can be altered through therapy or surgery, as in Sherry's case. The focus here is on the amplitude of the wave, which indicates the power of the sound, rather than its pitch or frequency.
