| Outline of Final Research Achievements |
In order to establish an objective evaluation method for mother-infant interaction, changes in the concentration of oxygenated hemoglobin (oxyHb) and deoxygenated hemoglobin (deoxyHb) in the frontal cortex of infant-mother pairs were measured using near-infrared spectroscopy (NIRS).
The changes were measured in three conditions: 1) Separation (the infant on a bed was separated from his/her mother by a screen); 2) Holding (the mother held her infant in her arms); and 3) Breastfeeding. Compared with the two levels in the Holding condition, the oxyHb and deoxyHb amplitude and frequency of infants during Separation were large. During Breastfeeding, the oxyHb and deoxyHb amplitude and frequency of infants and mothers were smaller than that of the other conditions. In addition, Breastfeeding was the condition with the highest rate of correlation between infants and mothers.
