1. PSYC 2314 Lifespan Development Chapter 8 The Play Years: Biosocial Development

2. Size and Shape Between 2-6 years, children grow almost 3 inches and gain about 4 ½ lbs. per year. By age 6, average child weighs about 46 lbs. and measures 46 inches. Body height and weight vary greatly from one child to another.

3. Size and Shape Factors Affecting Growth: –Genetic background –Health care –Nutrition

4. Size and Shape Because growth is slower during the preschool years, children need fewer calories per pound. Iron-deficiency anemia is the most prevalent nutritional problem among children. A common problem among American families of all social classes is children’s overindulgence in sweets, and most eat too few fruits and vegetables and too much.

5. Brain Growth and Development During childhood, the brain develops faster than any other part of the body. This maturation underlies children’s rapidly expanding cognitive and motor abilities. By age 5, the brain has attained about 90 percent of its adult weight, and by 7, it is full-grown. Several areas of the brain undergo notable expansion, esp. those dedicated to control and coordination of the body, the emotions, and thinking processes. Around age 5, growth in the corpus callosum allows children to better coordinate functions involve both sides of the brain and body.

6. Accidental Injury Factors: –Sex –SES –Neighborhood

7. Accidental Injury Injury Control –Think prevention –Think protection –Analyze injuries –Advocate safety

8. Mastering Motor Skills Gross motor skills improve dramatically between ages 2 and 6. While these abilities require practice, a certain level of maturation is also necessary. Children learn these skills by teaching themselves or by learning from other children. Fine motor skills are much harder for preschoolers to master.

9. Children’s Art Provides a means of practicing fine motor skills and enhances their sense of accomplishment. Also provides a testing ground for self- correction, and is related to overall intellectual growth.

15. Prevention of Maltreatment Primary prevention: occur early in the sequence that can lead to maltreatment, before the problems start. Secondary prevention: preventing serious problems by spotting and treating the early warning signs that indicate maltreatment might develop. Tertiary prevention: aimed at halting the harm after it occurs and treating the victim
