PSY 322 Lecture Notes - Lecture 8: Colostrum, Kwashiorkor, Breastfeeding
Document Summary
First evidence of motor skills is reflexes. By 3 months some reflexes go away and others morph into more advanced skills, especially when practiced. Development of motor skills improves exploration and cognitive development. Gross motor skills: movement of large muscles: develops from the head down and from the center out, overweight babies develop gross motor skills later than thinner babies, development of gross motor skills requires 3 interacting elements: 5 months: baby lifts head, wiggles, uses legs to inch forwards and backward on belly. 8-10 months: lift midsection and coordinate movement of hands and knees. Walking: requires a lot of coordination of multiple systems and practice. Fine motor skills: movement of small muscles. Movement of tongue, jaw, lips, toes, and fingers are very important. 3 months: babies reach and grab items with difficulty because of poor hand-eye coordination. 1 year: develop pincer grasp (thumb and forefinger)
