Listen to a conversation between two students. Can you give me an idea about what I missed in sociology class on Tuesday? Oh, it was really interesting. First you under over material on how infants normally shift to become more interested in people than objects. You know, at first babies just like to look at things, only later do they start to interact with people, and then we talked about play as a part of socialization of children. Play? You mean like games or make believe? Yeah, all different kinds of play. Apparently, it's important for children to experiment the different roles like pretending their parents instead of a child, also through the play that they learned to adapt to the norms as the rules of their social groups. Which of the reading did the professor refer to? A lot of them come from Erik Eriksson's work on psychological development. He said that for children play is not just a part of recreation the way as adults, when children played, they can deal with problems and they can learn then they even expressing things like fear and frustration.
