What is:

Vestibular sense?

and giving them meaning. So even though you and your friend are “seeing” the same stimulus, your

interpretations are different.)

Back to board

C2 - 100

100What is:

Absolute thresholds?(Dogs have sound receptors that can pick up higher frequency

sounds than do humans. This means that dogs have a lower absolute threshold for sound than do humans. That is, dogs’ sound receptors are more sensitive. Give yourself credit for

any related explanation. )
