Motivation, personality, perception, learning, values, beliefs, attitudes, and lifestyle influence consumer behavior. Motivation is the driving force behind behavior aimed at satisfying needs. It involves intensity, direction, and persistence toward goals. Maslow's hierarchy of needs categorizes needs from basic physiological needs to self-actualization. Perception is how people interpret sensory information to make sense of their environment. Learning occurs through conditioning and observation and influences recognition, responses to advertising, and brand loyalty. Personality consists of consistent traits that determine how people respond. Attitudes comprise affective, behavioral, and cognitive components. Expectations and satisfaction impact purchase decisions.
