Final answer:
The textbook authors propose using definitions that distinguish between emotional intelligence and emotional competence.
Step-by-step explanation:
The textbook authors propose using definitions that distinguish between emotional intelligence and emotional competence to correct the problem of multiple definitions of emotional intelligence. Emotional intelligence encompasses the ability to understand and regulate emotions in oneself and others, while emotional competence refers to the application of emotional intelligence in real-life situations. By using definitions that make this distinction, the authors aim to provide a clearer understanding of the concept.
