Kisilevsky and Muir (1991)recorded the responsiveness of a foetus to a sound via a microphone placed on the mother's abdomen by measuring movements and heart rate.They found that the foetus initially responded vigorously to the new sound but this response eventually declined to the point where it no longer elicited a response.This research established that foetuses:
A) can hear in utero
B) habituate
C) discriminate
D) show movement

Habituation is the process of becoming accustomed to a stimulus and no longer responding to it. In this study, the foetuses initially responded vigorously to the new sound but this response eventually declined to the point where it no longer elicited a response. This suggests that the foetuses were habituating to the sound.
