For this Assignment, select one developmental stage, such as infancy — ages birth to 2; early childhood — ages 3 to 6; middle childhood — ages 7 to 12; or adolescence — ages 13 to 18. Identify the physical, social, and cognitive changes that occur during that stage of development. Be sure to discuss at least one theory that fits best with the stage of development you have selected. Describe the theory and explain how it appropriately fits with your selected developmental stage. Finally, discuss the impact that cultural factors could have on your selected stage of development.Please use at least one other reference for your project besides the textbook for a total of two references.

Show how these theories help you to understand the developmental process from birth through adolescence. Piaget, Erikson, Vygotsky, Kohlberg, attachment theory, nature versus nurture, the influence of SES, and cultural implications are some of the major theories and concepts
