Erikson's stages of development theory!

There are 3 main periods during the prenatal phase: The germinal period, the embryonic period, and the fetal period.

# data[].attributes.body
The germinal period is essentially the time of conception to implantation of the fertilized egg. This is also the point when the sex of the fetus is already determined.

The embryonic phase is the next phase and consists of the early stages of development of the embryo. The sex organs of the fetus begin to form.

The third stage is the Fetal Period, the embryo has not formed into a fetus. Once the fetus has reached 24 weeks the majority of the neurons in the brain have developed. The fetus is also responsive to sound and light. The fetus will continue to grow until birth.

In infants, boys and girls are able to have erections and vaginal lubrication based of their sex from birth. This is a form of stimulation during their growth. Their gender Identity is not yet determined due to their early development of their personalities.

Gender Identity. The development of gender and gender identity appears to be due to an interaction among biological, social and representational influences (Ruble, Martin, & Berenbaum, 2006).

In toddlers and early childhood kids become more curious of their bodies and others. They will begin to touch their genitals more and once capable they will begin to ask more questions about each sex, for instance the difference in boys and girls. This is also where gender identity starts to take place. During this stage kids will become interested in each role the gender does. They will start to form their own self-identification based off their personalities to determine their gender identity.

Stage 4: Industry vs. inferiority
Stage 5: Identity vs. Confusion

The age of adolescence is an importing time for kids to be developing from each other because they are primarily spending the most time with each other. This is also the time when they know which gender identify as.

Stage 6: Intimacy vs. Isolation

Stage 7: Generativity vs. Stagnation

# data[].attributes.body
Stage 8: Integrity vs. Despair

This is the last and final stage of Erikson’s lifespan development theory. This is the age group from 65 years old till death. This is the time that people look back on their lives and feel either successful or regretful with their life choices. With integrity someone will look back on their lives and see a sense of accomplishment. With Despair they will reflect the feeling of disappointment and resentment.
