Scientists have   long been puzzled why peekaboo is   so popular among many children across different cultures. A recent study   suggests that this game appeals to   many children because it makes them think they are invisible. 
Some babies who   play this game feel confused and become upset when an object they see is   suddenly hidden from sight. According to scientists, this is related to Jean   Piaget’s [zhan pee-uh-ZHEY,   py-ah-] concept   of object permanence – the ability   to understand that an object still exists even though the child cannot see or   hear it. 
Lead researcher James Russell of the   University of Cambridge says that children believe people cannot see them   while playing peekaboo. 
To prove this claim, they conducted a study   that involved three and four-year-old children. The team covered the children’s   eyes with masks and asked whether the researchers could see them. Most of the   children answered ”no.” They thought that covering their eyes made them   invisible. 
Afterwards, the team let the children wear mirrored   goggles to test their perception of invisibility. The   researchers wanted to know if children think they are invisible because they could   not see anything at all or because someone could not see their eyes. 
Out of 37 children, only seven realized that   no one could see their eyes even if they could see others because of the   goggles. Six of the seven kids thought they were invisible although they know   that their bodies remain visible. 
The researchers also said that children think   they are invisible when their eyes do not meet other people’s eyes.
