First Explain the physical, social, and cognitive changes that are components of infancy
Second select and discuss one theory or concept that fits best with infancy. Describe and explain the theory, list the theorist (if there is any), and how this theory appropriately fits with your selected developmental stage.
Then select one theory, for example Erikson’s Psychosocial Stages of Development, and explain what this theory says about infancy. This is just an example and you are certainly not limited to this idea.
Lastly, discuss the impact that cultural factors could have on your selected stage of development.(Infancy) For example, in the infancy example you could discuss how culture may affect parenting styles.
