POLL EVERYWHERELinda has always had a passion for music. As a child she quickly learned to play the piano, and as an adult she has now mastered several other instruments. After Linda gives birth to Sam, she buys him Baby Mozart CDs and DVDS. She decides to enroll him in formal music lessons as soon as possible. Which of the following heredity-environment interactions is Linda providing evidence for?A.Evocative correlation.B.Active correlation.C. Niche-picking.D.Passive correlation.
LEARNING GOALS•Describe reflexes that infants are born with. Explain the purpose of reflexes and the developmental course of reflexes.•Explain the Dynamic Systems Theory of motor development.•Describe how the dynamic systems theory explains motor development across the lifespan.•Describe the Ecological Theory of sensory development. •Identify milestones in infants’ visual development.•Explain how heredity and the environment interact to shape visual development.•Describe the methods and results of the Visual Cliff experiment. Explain the conclusion that we can draw from this study.
THEORY: DYNAMIC SYSTEMS THEORY
MOTOR SKILLS AS DYNAMIC SYSTEMS•Mastery involves acquiring increasingly complex systems of action with each skill•Each new skill is a joint product of•Central nervous system development•The body’s movement capacity•The child’s goals•Environmental support for the skill
DYNAMIC SYSTEMS THEORY•Infants assemble motor skills for perceiving and acting•Motivationcreates new behaviors•Use perceptionsto “fine tune” movements with repetitive actions•Infants exploreand select possible solutions of new task; assemble adaptivepatterns
DYNAMIC SYSTEMS THEORY•New motor behaviors are the result of body’s physical properties, nervous system development, the goal the child is motivated to reach, and environmental support•Universal motor milestones achieved through process of adaptation•Crawling, reaching, walking
POLL EVERYWHEREWhat is/are the mechanism(s) of motor development according to the Dynamic Systems Theory?
