The persistence of primitive infant reflexes creates a level of immaturity of the brain. So, it’s not surprising that a child with these reflexes persisting shows immature behaviours. Such as, resistance to self help activities, dressing, taking responsibility, play choices and more. Some children use “baby talk”, or show an over-dependence on adults and other behaviours inappropriate to their age.

As the reflexes integrate, the changes in these features emerge until the child matches the maturity level of their peer group.
