“Self-control” is commonly understood to involve repressing or ignoring emotional reactions, leading to having a single response to a wide variety of situations. It often is linked to compliance to authority.
In contrast, the central concepts of self-regulation are self-awareness and the flexibility to assess and effectively respond to a wide variety of situations. It is based on decisions and actions made by a person, not on rules set by others. Sometimes a restrained or passive response is appropriate. At other times, the situation calls for passion and assertiveness. The goal of self-regulation is to be able to identify an effective state for the circumstances and to be able generate that emotional state as needed.
