Ethics

The one-word substitution for the group of words "morals that govern one's behavior" is ethics.

• Ethics is a system of moral principles that govern the conduct of a person or group.
• Intuition is the ability to understand something instinctively, without the need for conscious reasoning.
• Psychology is the study of the mind and behavior.
• Attitude is a settled way of thinking or feeling about something.

The word ethics is the most appropriate because it specifically refers to the moral principles that govern a person's behavior. The other words do not have the same connotation of being moral principles.
