What will be an ideal response?

Answer: The ideal answer should include:
1. The four panes are the open self, blind self, unknown self, and hidden self.
2. The open self represents all the information, behaviors, attitudes, and feelings about yourself that you, and also others, know.
3. The blind self represents knowledge about you that others have but you do not.
4. The unknown self represents those parts of yourself that neither you nor others know.
5. The hidden self represents all the knowledge you have of yourself but keep secret from others.
