Document Summary

Why is fear adaptive when babies begin to crawl: depth perception. Habituation: gradual reduction in strength of a response due to repetition. Recovery: new stimulus causes responsiveness to return to a high level. Imitation: newborns have ability to imitate, powerful means of learning, facilitates positive relationships. Milestones of reaching: prereaching - attempt, reaching with two hands then one, ulnar grasp adjust grip to object, moves object from hand to hand, pincer grasp using index and thumb. Differentiation theory: infants actively search for invariant features of the environment, gradually detect finer and finer features. Cephalocaudal growth: head to tail, lower part of the body grows later than the head. Proximodistal growth: near to far, center of the body outward, extremities grow later. Neuron growth & stimulation: neurons are made up of axons and dendrites. Synapse pruning: neurons that are seldom stimulated lose their synapses while those stimulated frequently establish new synapses. Schemes: psychological structures, organized ways of making sense of experience.
