According to psychologist Daniel Goleman, a strong IQ can set the baseline for success but does not guarantee prosperity. Goleman believes that factors contributing to "emotional intelligence" (for example, self-control, zeal and persistence, and ability to motivate oneself) are key to success in the corporate world. Howard Gardner has identified seven types of intelligence. Two of them intrapersonal intelligence (having true understanding of oneself) and interpersonal intelligence (understanding others) have implications for leadership. In 1990, Mayer and Salovey defined emotional intelligence as a type of social intelligence that involves the ability to monitor one's own and others' emotions, to discriminate among them, and to use the information to guide one's thinking and actions. The findings of research in the field of the neurophysiology of the emotions suggest that people can become effective leaders by learning to combine the strengths of their "thinking or rational brain" with those of their "emotional brain." Goleman has suggested the following domains for emotional intelligence: (1) knowing one's emotions; (2) managing one's emotions; (3) motivating oneself; (4) recognizing emotions in others; and (5) handling relationships. The next logical step is to move from review of the literature to research. This step will be accomplished by studying public school principals in Mississippi. (22 references) (MN)
