Chapter 12 & 13 1. What are some examples that demonstrate how infants of both sexes are born with the capacity for sexual pleasure and response? - The capacity for sexual response is present at birth. During the first two years in life boys and girls discover the pleasures of genital stimulation, they rub their genitals on toys or dolls. In some cases boys and girls have had what appears to be an orgasm. It is impossible to know what sexual experiences mean to infants, but they are gratifying. Many infants of both sexes continue in this gratification unless a negative vibe is given from the parents. Some girls will do pelvic thrusts, and for boys its erections, although ejaculation is lacking. 2. What are the common behaviors of sexual development that occur during childhood? - People show considerable variation in their sexual development during childhood. Common features in the developmental sequence tend to emerge. A child can learn to express their emotions by kissing and hugging. First the child does childhood masturbation, and then childhood sex play. Childhood masturbation involves the child rubbing or foundling the genitals on dolls of the bed. Childhood sex play is takes place with friends and happens as early as the age of 2 or 3. They would play house and rub themselves together to play sex. By the age of 8 or 9 boys and girls begin playing by themselves. The curiosity of sex still remains high. By the age of 10 or 11 kids are interested in body changes. This is when a child is first self-conscious about their body. 3. What is puberty and describe the physical changes that occur for males and females? - Puberty is a period of rapid physical changes in early adolescence during which the reproductive organs mature. This usually happens between ages 12 and 20. Puberty means to be covered with hair in Latin. When the child is between 8 and 14 the hypothalamus increases secretion that cause the pituitary gland to release large amounts of hormones known as the gonadotropins. In males they cause the testes to increase testosterone production and the females they act on the ovaries to produce elevated estrogen levels. From the age of 9 or 10 the levels of these gonadal hormones begin to increase as the child approaches puberty. Girls enter puberty at the age of 10 or 11 and boys at the age of 12. In the US 15% of girls begin puberty by the age of 7. Overweight girls enter puberty at earlier age than normal size girls. Developments happen on the outside, girls get breasts and pubic hair, boys get deeper voices and facial hair. A growth spurt also follows. Genitals also enlarge; the boys testes and penis and the girls labia. The only event of puberty that is different between boys and girls is growth. A growth spurt begins 2 years earlier in girls. The girls’ vaginal wall becomes thicker, and the uterus becomes larger and more muscular. Eventually menstruation begins, the first period is called menarche. The average age for a girls’ first menarche is 12.43 years old.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
