Motivation refers to internal states and conditions that influence behavior and give it direction in relation to physiological conditions, interests, attitudes, and aspirations. There are two components of motivation: needs, which arise from deficits within an individual, and drives, which are observable behaviors based on needs. Motivation functions by activating individuals, directing and regulating behavior, and selecting mechanisms. There are several theories of motivation including instinct theory, psychoanalytic theory, incentive theory, arousal theory, association theory, humanistic theory, cognitive theory, self-efficacy theory, and self-determination theory. Motivation can also be intrinsic, promoted by internal desires, or extrinsic, promoted by external factors. Motives are classified as physiological or psychological. Mas
