Which reflex is commonly not demonstrated by newborns with intellectual disabilities?

The rooting reflex is a common reflex seen in newborns, where they turn their heads in response to a stimulus on their cheek, typically to facilitate breastfeeding. This reflex is important for the instinctual feeding process.

Newborns with intellectual disabilities may display variations in reflex development due to neurological differences. However, the grasp reflex, reflexive blinking, and startle reflex are often preserved even in infants with intellectual disabilities. These reflexes indicate intact neurological pathways that are critical for basic protective and survival functions. Therefore, a lack or abnormality in the rooting reflex can be an indication of atypical development, which may be associated with certain intellectual disabilities.
