What are Primitive Reflexes?

A reflex is an automatic, instinctual movement that assists in development, growth, and survival. Blinking is a reflex. Many reflexes are active throughout our lives.

Other reflexes—called “primitive reflexes”—surface in the womb and infancy and are designed to become inactive in the first year or two of life. Primitive reflexes in infants are automatic, involuntary movements controlled by the brainstem that are present at birth and help with survival and early development. These reflexes, like the Rooting reflex and Sucking reflex (finding and receiving nourishment) are crucial for feeding, bonding, and basic motor development. Ideally, primitive reflexes merge into more sophisticated movements and become integrated. This integration process is facilitated by movement, sensory experiences, and the development of voluntary motor control. An integrated childhood reflex is one which has completed its function and is no longer triggered by its initial stimulus. In this process of integration, reflexes merge into other reflexes and/or voluntary movements.
