Reflex Development
Innate tactile, proprioceptive, and vestibular input reactions
Neonatal Period - answerTactile, proprioceptive, and vestibular inputs are critical from birth
onward for the eventual development of body scheme.
Vestibular system, although fully developed at birth, continues to be refined and impacts on the
infant's arousal. Helps the infant to feel more organized and content.
Visual system develops as infant responds to human faces and items of high contrast places
approximately 10in from the face.
Auditory system is immature at birth and develops as the infant orients to voices and other
sounds.
First 6mo - answerVestibular, proprioceptive, and visual systems become more integrated and lay
the foundation for postural control, which facilitates a steady visual field.
Tactile and proprioceptive systems continue to be refined, laying the foundation for development
of somatosensory skills.
Visual and tactile systems become more integrated as the child reaches out and grasps objects,
laying the foundation for eye-hand coordination.
Infant movement patterns progress from reflexive to voluntary and goal directed.
6-12mo - answerVestibular, visual, and somatosensory responses increase in quantity and quality
as the infant becomes more mobile.
Tactile and proprioceptive perception becomes more refined, allowing for development of fine
motor and motor planning skills.
Tactile and proprioceptive responses also lead to midline skills and eventual crossing of midline.
Auditory, tactle, and proprioceptive perception is heightened allowing for development of sounds
for the purpose of communication.
Tactile, proprioceptive, gustatory, and olfactory perception are integrated, allowing for primitive
self-feeding. [Show Less]
