1. Developmental Psychology Introduction to the Study of Development & A Look at Physical Development

2. Development Sequence of age-related changes from conception to death Two Themes – Transition – Continuity

3. Universals and Specifics Universals Universals: what developments are normal for most people, regardless of their culture, experiences, etc? Specifics: Specifics: what are the variations in development?

4. Developmental Course Stages – period which patterns of behavior are established and exhibited Developmental Norms - median age which individuals display certain behaviors and abilities

5. Continuous and Discontinuous Development

6. The Study of Development 1.Longitudinal Design – observe one group over time 2.Cross-Sectional Design – compare groups of different ages at one time

7. PHYSICAL DEVELOPMENT Prenatal, Childhood, Adolescent, & Adult Development

8. Prenatal Milestones The 40 Weeks of Pregnancy Day 1 First Day Of Period Day 14 Ovulation Day 23 Implantation Day 1- Implantation The Germinal Stage Implantation- Week 10 The Embryonic Stage Week 11- Birth The Fetal Stage Organ Structures Completed Sex Differentiation Growth and Differentiation Week 23 Viability Full-term 38 Weeks Movement

9. Prenatal Development 9 months from conception to birth – Germinal Stage – Embryonic Stage – Fetal Stage

10. Germinal Stage First 2 weeks Zygote Cell division 7 th day attaches to uterine wall 1 in 5 pregnancies end here

11. Embryonic Stage 2 weeks – 2 nd month Embryo Form vital organs (heart, spine, brain)

12. Fetal Stage 2 months - birth Fetus Rapid body growth Develop sex organs Brain cells multiply Age of Viability – (22-26 weeks)

13. Teratogens General Principles Effects are dose dependent Effects depend on genetic and health factors Effects vary according to stage of development

14. F ETAL A LCOHOL S YNDROME Symptoms include low birth weight, face and head abnormalities, slight mental retardation, and behavioral and cognitive problems

15. REVIEW GERMINAL – Zygote – Rapid Cell Division EMBRYONIC – Embryo – Vital organs FETAL – Muscle, bone, brain, & sex organs – Age of viability

16. Childhood Brain Development most development occurs in the cortex the brain triples its weight in the first three years following birth. initial burst of development in first year pruning pruning begins after second year and continues through adolescence

17. Childhood Motor Development

18. Childhood Physical Development Motor Development – Cephalocaudal Trend head-to- foot – Proximodistal Trend center- outward

19. Maturation Gradual unfolding of genetic blueprint

20. Adolescent Physical Development Adolescents – (13 -22) – Pubescence – 2 yr period of physical maturity before puberty Secondary Sex Characteristics – Puberty – begins adolescents Primary Sex Characteristics

21. Puberty & Physical Development Menarche – 1 st menstruation – Marks Girls’ Puberty Spermarche – 1 st ejaculation – Marks Boys’ Puberty

22. Teen Brain Immature Prefrontal Cortex – Explains reckless behavior?

23. Adult Physical Development Lose hair, sight, and hearing Menopause Decline in brain tissue & weight

24. Adult Physical Development Dementia An abnormal condition marked by multiple cognitive deficits that include memory impairment

25. UPCOMING ATTRACTIONS... COGNITIVE DEVELOPMENT MORAL DEVELOPMENT EMOTIONAL DEVELOPMENT PERSONALITY DEVELOPMENT
