A history lesson

I explored what Psychologists had to say about my topic. 
According to Psychologists, sentimental objects are called "security"/ "transitional" objects. A common use for security objects is to help the child transition into reality. They are used as a child begins to separate from his mother and realize that him and his mother are not the same person.While this happens, the child experiences anxiety and fear. In order to reliever the child of his fear, he takes on a comfort object in place of his mother. 
The psychologist's also  realized that children have a greater sense of self confidence if they have a comfort object. So that answers my question--yes, there is an advantage to having a comfort object. Richard H. Passman, from the University of Wisconsin, conducted this experiment --so I will be using him as a large part of my project. 
I also decided I want to investigate how modern technology portrays comfort objects- as a good thing, or a bad thing? (On Tv, in newspapers, etc.)
