It affects the way we communicate with others. For example, if we have a positive self-concept, we are more likely to communicate effectively because we believe in ourselves and our communication ability. We are also more likely to be assertive, which means that we are more likely to speak up and express our needs. On the other hand, if we have a negative self-concept, we may be less likely to communicate effectively because we doubt our ability to do so. We may also be less assertive, so we may not speak up or express our needs as clearly.
