Midterm Stats & Numbers

L1 - Intro to Human Development

Life Expectancy:

• Early 1900s = 57years

• 2021 = 82.60 years

Periods of Development

1. Prenatal = conception to birth

2. Infancy = 0-2

3. Childhood = 2 to 10-12

4. Adolescence = 10-12 to 18-22

5. Early Adulthood = late teens/ early 20s - 45

6. Middle & late Adulthood = 45-60 and 60 to death

L2 - Theories of Development

Eriksons Psychological Theory

1. Infancy = 0-2 Trust vs Mistrust

2. Early Childhood = 2-3 autonomy vs Shame & doubt

3. Preschool = 3-5 initiative vs guilt

4. School age = 6-12 industry vs inferiority

5. Adolescence = 12-18 identity vs role confusion

6. young adulthood = 19-40 intimacy vs isolation

7. Middle adulthood = 40-65 generativity vs stagnation

8. maturity = 65+ integrity vs despair

Piagets Stages of Cognitive development

1. Sensorimotor = Birth - 2

2. preoperational = 2-7

3. Concrete operational = 7-11

4. Formal operational = 11+

6 substages of sensorimotor

1. simple reflexes = first month

2. primary circular reactions = 1-4 months

3. Secondary circular reactions = 4-8 months

4. Coordination of secondary circular reactions = 8-12 months

5. Tertiary circular reactions = 12-18 months

6. Beginnings of though = 18 - 2 years

L3- Genetic Foundations

Cell nucleus = 25,000 genes

Chromosomes = 23 pairs, 46 total

Mitochondria = 37 genes from mom

CF numbers

1 in 2,000

PKU numbers

1 in 10,000 - 1 in 20,000

both parent have gene = ¼ chance of child to develop
