4. Do you have a chld of 2 to 7 years in your life? Look at some aspect of language development or read about Piaget's stages of cognitive development(page 373-374) and try a conservation experiment with him or her. Alternatively, consider "egocentrism" or the research on the "theory of mind."Can you find examples of these?
I work at a Lifetime Fitness child center, so I am constantly around kids ages 3 months to 12. It is so interesting to see how the behaviors change in just a few months, especially the babies. From the initial babbles to the first words, it is so incredible to observe. It is also fun to see the difference between three and four year olds. Between that small age difference the personality growth is immense. They are able to form a conversation and are beginning to be less egocentric. Also they start verbalizing favorites and like and dislikes. I think the old television show "Kids Say The Darnedest Things" is a great example of the stages of cognitive development. The host poses a question that an adult would find a 'no brainer' , but the kids give elaborate answers that make complete sense to them.
