PSYC-223 Lecture Notes - Lecture 3: Executive Functions, Stroop Effect, Object Permanence
Document Summary
5. 3 motor development (chapter 5. 3, 6 and 9 are the focus) Motor milestones are hit at different times for different babies (supervised tummy time necessary for being able to push them up into crawling posture) Walking begins after standing, usually at about a year and after they use furniture for support. Evidence of experience: tribes in uganda have accelerated motor development; by being carried in sling the babies has to adjust its posture (legs and stomach) to keep themselves upright develop muscles quicker. Excessive swaddling slows motor development: at older ages, the baby gets less exercise. Orphanages and too much crib time: delayed motor development from being supine. Tummy time: during waking, this helps develop muscles. Locomotion positively influences cognitive skill: so to an extent earlier locomotion is better. : no exercise (control), vs eliciting stepping reflexes actively, vs passively pumping the legs.
