Outline of Final Research Achievements

We explored how individual differences (e.g., physiological and psychological responses to music, emotional state during music listening, temperament, diet, everyday behaviors) in 78 expectant mothers would influence fetal movements to music during middle to final stages of pregnancy (18-36 weeks GA). We also investigated developmental changes in fetal movements to music in two contexts: when music was presented to the mother through a headphone and when music was presented to the fetus through a speaker with normal amplitude while the mother was listening to an ocean-wave-like noise through a headphone. Music consisted of 12 1-min-long cello pieces. Results showed that approximately 20% of fetuses moved more during music regardless of GA or context. Emotional nuances of music influenced fetal movements at or after 23 weeks GA. Moreover, the fetus tended to move more when the mother was involved in everyday practice including diet and hobbies that could reduce stress.
