To determine:
How might the development and behaviors of sleeping infant be affected by sounds of their arguing parents.
Concept introduction:
fMRI studies reveal that sleeping babies can register the sound of arguing. This is determined by the amount of blood flow to different regions of the brain. This activity suggests that the infants can hear their parents arguing even while they are asleep.
Explanation of Solution
Suggested response:
Hearing arguing while sleeping could cause the infants to feel tension or anxiety. If the arguing is loud or especially tense, the babies’ sleep may also be affected. The baby may wake often during the night or be fussy during the day. Parents who argue a lot may also experience more negative emotions, which may affect the infants’ moods, too. Plus, they may not show adequate warmth to their babies, an outcome that could interfere with attachment and brain development.
