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.

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.
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 ...
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 ...

Simple reflexes: From birth to one month old. At this time infants use reflexes such as rooting and sucking. First habits and primary circular reactions: From one month to four months old. During this time infants learn to coordinate sensation and two types of schema (habit and circular reactions).
It means that organisms with simple reflexes begin to cognize the environment in collaboration with caregivers. However, different viewpoints on this issue - the binding problem [35] and the primary data entry problem [36] [37] - challenge the ability of children in this stage of development to meaningfully interact with the environment.
