Babies younger than 6 months of age do not recognize their mothers watching their mobile phones. Babies recognize a face from profile view after 6 months of age.
Longitudinally testing 14 babies every month during the first 3 to 8 months of life, scientists at Chuo University and other institutions first identified developmental changes in babies with regard to the ability to recognize a face from frontal and profile views. Adults and children easily recognize faces from both the frontal and profile views, whereas newborn babies do not. To investigate the age when we are able to recognize the face regardless of view change, they measured a baby’s brain activity while the baby viewed frontal and profile views of the face using non-invasive near-infrared spectroscopy.
