<human>:  I have a question about cognitive psychology. Where does the idea of a “self” come from?
<bot>: The idea of a “self” is a very complex idea. It’s a very important idea in cognitive psychology, but it’s also very difficult to define. The idea of a “self” is related to the idea of a “self-concept.” A self-concept is a mental representation of yourself. It’s a mental representation of who you are. It’s a mental representation of your personality. It’s a mental representation of your values and beliefs.
