Palmar grasp reflex — in infants up to six months of age, a closing of the hand in response to an object being placed in it. Periroral reflex: when a finger is placed at the angle of the mouth and struck, or the nasolabial fold is stroked, mouth closure is induced via CN VII [1] Pharyngeal reflex — also known as the gag reflex.
For example, children with learning difficulties have been found to exhibit persistent primitive reflexes. [25] In addition, a persistent ATNR has been found to be associated with lower reading and spelling scores, [26] and children with reading problems tend to display the tonic labyrinthine reflex more than children without reading problems.

Simple reflexes: Birth–6 weeks "Coordination of sensation and action through reflexive behaviors". [36] Three primary reflexes are described by Piaget: sucking of objects in the mouth, following moving or interesting objects with the eyes, and closing of the hand when an object makes contact with the palm (palmar grasp). Over the first six ...
For newborns, grasping is a natural reflex. A grasp is an act of taking, holding or seizing firmly with (or as if with) the hand. An example of a grasp is the handshake, wherein two people grasp one of each other's like hands. In zoology particularly, prehensility is the quality of an appendage or organ that has adapted for grasping or holding.
For example, infant's relatively poor perceptual skills protect their nervous system from undergoing sensory overload. The fact that infants have slow information processing prevents them from establishing intellectual habits early in their lives that would cause problems later in life, as their environments are significantly different.
Grasp reflex. Newborn babies have a number of other reflexes which are not seen in adults, referred to as primitive reflexes. These automatic reactions to stimuli enable infants to respond to the environment before any learning has taken place. They include: Asymmetrical tonic neck reflex; Palmomental reflex; Moro reflex, also known as the ...

[30]: 171, 578 While the actions of short-loop reflexes are fixed, polysynaptic reflexes can often be regulated by instruction or prior experience. [31] A common example of a long loop reflex is the asymmetrical tonic neck reflex observed in infants.
