Jean Piaget - focused on the cognitive behavior of babies. He studied how children made similar reasoning for the answers.

Eric Erickson - studied the changes in motivation.
This study shows how and why children become less motivated or motivated based on the upbringing of the child.

Lawrence Kohlberg - studied the unchanged and moral thinking. This involves how the upbringing and and culture can affect an individual based on their upbringing.

Continuitie plays a big role in developmental psychology it shows how perception and language skills differ, it also shows wether the development is consistent or unconcinaiatent over time.

Piaget, Erickson and Kohlbergs observation share similarities when it comes to the age of the child which involves Nature vs Nurture

I learned that scientist have conducted several experiments with identical twins to see whether or not their genetics play a role in the weather they are separated or not .
They have also tried  assessing wether the genes are more dominant in the behavior of the twins. More research has to be made to see if thinking or acting out is based primarily on the environment.

I learned that identical twins share the same exact DNA.  Although they have the exact DNA twins can act completely different based on their environment.
The primary reason why scientist use identical twins for their obersavtion, is to find out wether or not their behavior is contributed through genetics or the environment.
