Document Summary

Two newborn movement classes: spontaneous: movements not caused by known external stimuli, reflexive: stereotypical, involuntary responses elicited by specific external stimuli. Reflexes: reflexive movements occur quickly after onset of stimuli, they involve single muscle or a specific group of muscles (not whole body) Infantile reflexes are only seen during early development: 3 types: primitive, postural, locomotor, purpose, built-in responses facilitate survival, refle(cid:454)es allo(cid:449) (cid:862)dialogue(cid:863) (cid:449)ith e(cid:374)(cid:448)iro(cid:374)(cid:373)e(cid:374)t, reflexive movements result in sensory consequences (adaption, reflexes provide building blocks for future movement. Reflexes vs. spontaneous: reflexes: specific to external stimuli, localized & the same stimulus will elicit a corresponding reflex over and over again, spontaneous: do not result from external stimuli & are more generalized in nature. Infant starts in supine position: stimulus: turn head to one side, response: same-side arm & leg extended, normal: 0-4 months, problematic: >6 months, could indicate developmental problem but not necessarily.
