What theory did Erik Erikson develop?
The Neo-Freudian Psychoanalytic theory.
What are psychosocial stages?

Humans engage in active processing of information that plays a role in their learning, behavior and development.
What is observational learning?
using other people as models to learn.
What are the necessary components to engage in observational learning?
paying attention, constructing and remembering mental representations, retrieving and using these representations when necessary.
What experiment goes along with observational learning?
Bobo the doll - some children saw doll praised, others day it punished and others saw no consequences; children could reproduce these actions for their own afterwards, so children can learn actions.
