This chapter describes leadership behavior as the sum of two dimensions: Expressed Behavior is what people see, and Internal Behavior is what people perceive. Behavior is never neutral. It is always affecting someone or something. It is always being perceived and interpreted by others. Within an organization, a leader's behavior range of influence is 360 degrees with impacts on a leader's subordinates, peers, bosses, customers, government regulators, and everyone the leader encounters. The impact of one person's behavior on another is largely neurological, that has to do with electrically excitable cells that process and transmit signals from the brain throughout the nervous system. "Habits can be defined as psychological dispositions to repeat past behavior. Internal behaviors are referred to as Emotional Intelligence, "a set of emotional and social skills that influence the way we perceive and express ourselves, develop and maintain social relationships, cope with challenges, and use emotional information in an effective and meaningful way".
