Invisible Gorilla or Optional Book

As you know, we have been examining personality.  You have read how Feud's theory laid the ground work for personality development, how the humanist view personality development and we are currently looking at the trait perspective and will finish that up today.  However, tomorrow you have an assignment due to me.  This is a reminder of the due date and I hope that you all did not wait until the last moment.  However, here is an additional assignment for extra credit that is due to me tomorrow if you choose to complete it.  I want you to answer the following question using information from your book to make your assumption/prediction.  How would the author(s) of you book explain personality development, and which theorist would your author best get along with?  This should be roughly a page in length.  Good luck!
