The tendency to look for information that supports one's own belief is called ________

What is the principal difference between amplitude and frequency in the context of sound waves?

A) Amplitude is the tone or timbre of a sound, whereas frequency is the pitch. B) Amplitude is detected in the cochlea, whereas frequency is detected in the auditory cortex. C) Amplitude is the height of the sound wave, whereas frequency is a measure of how frequently the sound waves pass a given point. D) Both measure qualities of sound, but the frequency is a more accurate measure since it measures the shapes of the waves rather than the strength of the waves. E) Frequency is a measure for the light waves, whereas amplitude is a measure for sound waves.

A major limitation of correlational studies is that

A) researchers cannot study how conditions of interest currently exist. B) researchers cannot infer cause and effect. C) there is no way to measure the strength of a positive relationship between variables. D) negative relationships between variables cannot be measured.
