We've evolved to react automatically to some things; for instance newborn babies are born with the reflex to 'suck' if an object is put into their mouth and 'swallow' liquid, e.g. milk, in order to survive. If that was something that had to be learnt, they wouldn't live long enough to learn it. Or if we are exposed to extreme heat, like fire, our reflex is to move away from it, or we would get burnt. The well-known 'knee-jerk' reflex, combined with other muscles, helps us to walk without needing to think about each step. Through natural selection, animals and humans with these extra survival abilities have lived to pass on their genes, wheras the ones who died of malnourishment as infants, or were burnt to death, didn't.

What is the purpose of newborn reflexes?

Newborn reflexes help infants survive and thrive in their new environment by aiding in feeding, protection, and interaction with caregivers. These reflexes are automatic responses to stimuli and gradually disappear as the baby's nervous system matures.


Inborn or intristic reflexes are what?

Inborn or intrinsic reflexes are automatic responses that are typically present at birth and do not require prior learning or conscious thought to occur. These reflexes help protect the body and are controlled by the spinal cord or brainstem. Examples include the knee-jerk reflex and the sucking reflex in infants.


Innate physiological dispositions to respond to the environment in certain ways that are present in infancy are called?

Innate physiological dispositions to respond to the environment in certain ways that are present in infancy are called reflexes. These reflexes are automatic, involuntary responses to specific stimuli and help infants survive and interact with their surroundings.


When do newborn reflexes disappear?

Newborn reflexes typically begin to fade within the first few months of life as the baby's nervous system matures. For example, the rooting reflex usually disappears by around 4 months, while the Moro reflex fades by 4 to 6 months. Other reflexes, like the grasp reflex, can last until about 5 to 6 months of age. These timelines can vary slightly among infants.


What is the function of reflex behaviors and why do they change during the early months in infants?

Reflex behaviors in infants serve to protect and support their early development. These reflexes are instinctual reactions to stimuli, such as sucking when something touches the baby's lips. As the infant's nervous system matures, reflex behaviors gradually disappear and are replaced by intentional movements controlled by the brain.
