This simulator lets you trigger each primitive reflex on a virtual newborn and watch how the response changes as the infant ages, showing exactly when normal reflexes should fade.
Select a reflex, apply its trigger stimulus, and slide the age control forward to see how the response strength changes from birth through around 6 months.
Use the reflex selector to choose a primitive reflex, the trigger button to apply its stimulus, and the age slider to observe how the response changes with development.
The Babinski reflex is unique among primitive reflexes because doctors also test for it throughout adulthood, since its reappearance later in life can signal a neurological problem rather than being expected and normal.
