The document discusses factors that influence consumer behavior. There are four main types of factors: cultural factors, social factors, personal factors, and psychological factors. Cultural factors include culture, subcultures, and social classes that shape a person's values and preferences. Social factors encompass reference groups like family, friends, and social roles/status that provide social influence. Personal factors relate to demographics like age and lifestyle as well as income that impact purchasing power. Psychological factors refer to personality, self-concept, and motivations that underlie consumer decision making. Understanding how these various factors intersect is important for marketers to effectively target and influence consumers.
