9. Studying Development Cross sectional method – Studying various groups at various ages at the same time. Problems – Groups may not be typical of their age groups.

10. Prenatal Development  Development that takes place before birth is very important.  By end of first month, heart has developed, and by the second month, systems have befun.  By the fourth month, all biological patterns have been set

11. Physical Development This is the growth of the physical body. The development of one’s physical characteristics is extremely important to a person’s behavior.

By three years old, a person is ½ as tall as they will get. By three years old, a person is ½ as tall as they will get. Girls grow faster but are passed up eventually. Girls grow faster but are passed up eventually. Weight will be gained – lost at end Weight will be gained – lost at end

13. Impact of physical development on personality Early maturing males are more self- confident and independent Early maturing males are more self- confident and independent Late-maturing males have a difficult time adjusting. Late-maturing males have a difficult time adjusting. Females aren’t impacted as much Females aren’t impacted as much The behavior of others influence people’s attitudes of their own physical development. The behavior of others influence people’s attitudes of their own physical development.

14. Motor Development The development of control over the muscles of the body. Motor development is essential to forming relationships. Also related to self-image.

15. Motor Development in Babies Motor skills start in the head, and happens very quickly. The next step is the trunk area, so babies can turn over. Then, the arms and hands develop.

16. Motor development in later life Motor skills improve greatly during adolescence. Skills continue to improve until the middle 20’s. As you get into older age, motor skills begin to deteriorate.

17. Hand-eye Coordination It is extremely important for us to see our hands to improve our motor skills. Experiments have shown that organisms who couldn’t see their hands often struggled with motor skills.

18. Language Development Language has common features that everyone uses. Language has common features that everyone uses. Vocabulary are the words that make up a language. Vocabulary are the words that make up a language. Meaning must be placed on each word. Meaning must be placed on each word.

26. Social Development Learning to act and live in society as a member of that society. It occurs through associations and learning from others.

27. When does social behavior appear Early on, infants respond to face like objects. Two month olds cry when an adult leaves the room and smile when the adult returns. Three stages with adults: A. Dependence B, Resistance C.Cooperation

28. Social Changes in Early School Kids see conflicting ideas Children begin to adopt the standards of their age group. Between age 8 and adolescence, kids tend to migrate toward their own gender when choosing friends.

29. Social Behavior of Adolescents Adolescents strive to be independent from the home. They rebel over minor things. There is a gap between their ideas and their parents. Increase interest in opposite sex.

33. Piaget’s four stages of intellectual development Piaget’s four stages of intellectual development

34. 1. Sensory-Motor Period Kids use their senses and movement to interact with environment. Kids use their senses and movement to interact with environment. Develop cause and effect. Develop cause and effect. By nine months, they realize that even if they can’t see something, it is still there. No longer, out of sight out of mind.

Kids start to think logically and realize that quantities may not change because shape changes. Example: An equal amount of water is poured into differently shapes glasses, this stage’s kids can understand that they have the same volume of water. Example: An equal amount of water is poured into differently shapes glasses, this stage’s kids can understand that they have the same volume of water.

37. 4. Formal Operational (age 11+) In the stage, people will combine various possibilities to solve a problem. Experiment with cause and effect and use logic. In the stage, people will combine various possibilities to solve a problem. Experiment with cause and effect and use logic. Researchers have found that only 30-40% of adults actually use formal operations. Researchers have found that only 30-40% of adults actually use formal operations.

38. Moral Development  Individual development of knowing the difference between right and wrong.  Lawrence Kohlberg – believed that there were six moral development, going up in complexity.

39. Measuring moral development  One way to measure is to give a person a “moral dilemma” and look at their decision making.  Then, after the decision is made, psychologists look at the answers and why the people made the decisions they made.

40. Six Stages of Moral Development  Stage 1 – Children base their answers on avoiding punishment.  Stage 2 – Children make moral judgments according to what behavior will bring them rewards.  Stage 3 – People make moral decisions based on what will please or avoid disapproval from others.

41. 6 Stages  Stage 4 – Involves a respect for authority and society’s norms.  Stage 5 – Moral judgments are based on the welfare of the community and rights of others.  Stage 6 – Decisions are made based of personal principles of justice.

42. Stages 5 and 6  Have more fully developed standards of morality.  Stage 5 recognized different societies have different standards.  Stage 6 realizes that some moral standards are universal.

43. Criticisms of Kohlberg  Some psychologists say that moral development doesn’t always happen in stages.  Moral reasoning is different than moral behavior – people say one thing but will do another.
