5-How We Learn to Communicate
This lecture is a study of the methods of communication that develop in the brain. As babies we first learn how to pick out significant objects from the chaos around and to name them. From these habits we learn how to speak about ourselves. Later brain habits are largely directed to ensuring co-operation between individuals. The most primitive forms of communication were probably sexual, and to these have gradually been added methods of acting that bind us together into families and larger social groups.
