Many parents are delighted when their baby’s first words are either “mama” or “dada.”
Beyond the obvious, Mommy and Daddy are always there, languages in many cultures have apparently made the task easy by creating words for mothers and fathers that feature patterns of repeating sounds, a new study suggests.
Brain activity increased in the babies’ temporal and left frontal areas whenever words that end in repeating syllables, such as “mubaba” and “penanathe repetitious words were played. Words with non-adjacent repetitions (”bamuba” or “napena”) elicited no distinctive responses from the brain.
This would suggest that babies first words are a result of science instead of nurturing alone.

Swiss and German researchers found that children are more likely to share when they reach the age of seven.
The researchers studied the behaviour of 229 Swiss children and found that while kids aged three to four showed no tendencies to think beyond their own needs, children aged seven to eight had developed a sense of fairness and understanding of inequality, which led them to share more often with other children.
The researchers conducted three tests; the “sharing” test, the “envy” test and the designed to measure “prosocial” behaviour
The researchers concluded that these results prove that”human egalitarianism and parochialism have deep developmental roots.”
