defensive

Hidden or Secret Self
The person knows aspects about his or her
behavior and professional practice that the
colleague or supervisor does not know.
 The person tends to conceal these for fear that
the supervisor may use them to punish, hurt, or
exploit.
 This “cell” demonstrates the importance of a
climate of trust and credibility.

Blind Self
The supervisor knows about aspects of a
person’s behaviors and professional
practice of which the person is unaware.

supervisor know all the potential for the
person’s behavior and professional
practice.
