Document Summary
Key terms: growth - changes in height, weight and body composition, motor development - changes in control and proficiency in movement, fine motor skills - small muscle movements. Picking up a cheerio: gross motor skills - large muscle movements. Infants gain approx. one pound per month. Birth size does not predict adult size. Early development does not reflect cognitive abilities: early childhood (3-5 years) Growth slows to about 2-3 inches in height and 5 pounds per year. Children"s size at 4 years strongly correlates (r=. 80) with adult size. Gross and fine motor skills continue to be refined. Most dramatic motor development is in quality of walking: middle childhood (6 to 12 years) Keeps to an average of 2-3 inches and 5-6 pounds per year. Quality of fine motor skills increase dramatically. Physical activity peaks: adolescence (13-19 years) Timing and speed of growth varies widely. Teens that spurt early do not necessarily become tall adults.
