A non-stressful auditory stimulus was presented to 11 mothers during their last trimester of pregnancy. Maternal and fetal heart rate and fetal activity were recorded. The data indicated significant changes in the fetal heart rate to the first 2 min of the stimulus presentation. While it was not possible to clearly determine whether the maternal response mediated the fetal change or whether the fetus responded directly to the stimulus, the data suggest that the former hypothesis was the more parsimonious.
