Document Summary
Brian cells are sculpted by heredity and experience. Birth: neuronal growth spurt(synaptogenesis) and synaptic pruning. 3-6 months: rapid frontal lobe growth and continued growth into adolescence and beyond. Early childhood: critical period for some skills (i. e. , language and vision) (pruning) Maturation takes place in the body and cerebellum enabling the sequence below. Physical training generally cannot change the timing. Beginning to walk(12 months) walking independently (15 months) (just averages, large variability) these new skills change their environment drastically. Infantile amnesia: brain forms memories so differently from the episodic memory of adulthood that most people cannot really recall memories from the first three years of life. A birthday party when turning three might be a person"s first memory. More salient, more likely remembered (such as birth of sibling or hospitalization) Still have implicit, procedural, memories of how to do things and learning skills. 3-year-old can learn, and recall a month later, that specific foot movements move specific mobiles.
