Document Summary
Developmental psychology chapter 11: physical development in middle childhood. On average both boys and girls gain around 5-7 pounds per year: children"s bodies become more muscular and they start to lose the baby fat. It is unusual for kids of the same age to be 6 or 7 inches apart in height. Children double their strength: boys typically are stronger due to their greater number of muscle cells. Significant tooth development occurs during middle childhood: around age 6, primary teeth start falling out and are replaced by adult teeth, fall out at a rate of about 4 per year starting at age 6. Kids who receive more nutrients are more involved with their peers, showed more positive emotion, had less anxiety and had more activity levels than their peers that had less adequate nutrition. Nutrition is linked to cognitive performance: better verbal abilities, malnutrition may dampen children"s curiosity, responsiveness, and motivation to learn.
