Document Summary

Early motor behaviour: reflexive or spontaneous (clark, 1995, reflexive, stereotypical responses elicited by specific external stimuli, spontaneous, movements not caused by known external stimuli. Spontaneous behaviours: original theory: extraneous, no purpose, current theory: building blocks, similar to some voluntary movements, examples, spontaneous arm movements (resemble reaching, spontaneous kicking (resembles adult walking) Reflex: reflexive movements occur quickly after onset of stimuli, they involve single muscle or specific group of muscles (not whole body), they cannot be extinguished at any one time, persistence may indicate neurological problems. Purposes of reflexes: built-in responses facilitate survival, reflexes allow dialogue with environment, reflexive movements result in sensory consequences (adaptation), reflexes provide building blocks for future movement. Infant starts in supine position: stimulus: turn head to one side, response: sameside arm and leg extend. Palmar grasp reflex: stimulus, touch palm with finger or object, response, hand closes tightly around finger or object.
