| Outline of Final Research Achievements |
The aim of this study was to determine how a young adult’s brain responds to emotional infant stimuli. We utilized a near-infrared spectroscopy technique to investigate oxygenated hemodynamic changes in the prefrontal and temporal cortices of young adults while watching an infant facial expressions and producing infant-directed speech (IDS). Moreover, we examined the influences of infants’ moods on the brain activities of young adults. Twenty-four healthy young adults with no childcare experience participated in these inspection experiments. We assigned two kinds of activation tasks to them: watching infant’s facial expressions and producing IDS to an infant. We found that both of the dorsolateral prefrontal cortex and the ventrolateral prefrontal cortex were more activated when the young adults were watching or speaking to infants in a good mood. These findings suggest that a young adult’s hemodynamic response in the prefrontal cortex strongly depends on the infant’s mood.
