| Research Abstract |
We explored how fetuses (N = 18) of different developmental phases (18-27 and 28-37 weeks GAs) would respond to low-to-middle-pitch-range cello pieces in two different contexts: When they were played to mothers through a headphone, and when they were played through a speaker with normal amplitude (70 dB) while the mother was listening to an ocean-wave-like noise. The fetal movements were recorded by the ultrasound, and leg and arm movements were coded by means of the Observer XT. The movement data during the baseline and each type of musical exposures were analyzed by lag sequential analysis, which provided Z scores representing the degree of contingency between music and movement. Results showed that only fetuses of 28-37 weeks GA moved either legs or arms more often when music was presented through a speaker than the other context. Moreover, this later stage of fetuses moved more when the mothers were listening to "tender" than "happy" pieces through the headphone.
