Suppose an infant habituates to the sound "ba" and fails to change its sucking rate when we substitute the sound "bla." what interpretation would follow from this result? the infant prefers the sound "ba." the infant prefers the sound "bla." the infant does not hear a difference between the sounds. the infant cannot hear either sound.

explanation:

its temperature is increasing. this causes molecular vibrations to increase.
