Infants are not startled by visual illusions

A recent study reveals that infants aged six months and older can perceive misbinding, a type of visual illusion where features are mistakenly integrated. In contrast, infants under six months do not exhibit this phenomenon, indicating they may perceive the external world more accurately than adults.

Babies can see things that adults cannot

Infants younger than 7 months can perceive faces even when they are followed by a mask image, but this ability disappears in older infants. The study found that visual backward masking occurs due to interference with feedback processing, which develops in the second half of the first year of life.

Infants recognize rapid images, just like adults

Researchers found that infants aged 7 and 8 months could identify two faces when the temporal interval was 800ms, but overlooked the second face when separated by 200ms. This suggests that infants take less than a second to process visual information and have the same temporal limitation as adults.

Mom, I can't recognize your face from profile view!

Babies younger than 6 months fail to recognize their mothers' faces when watching mobile phones, but improve face recognition at around 5.5 months through increased brain activity in response to profile views. Longitudinal testing of 14 babies from 3-8 months old provided key insights into developmental changes in face recognition skills.
