Consumer psychology is the study of how people think, feel, and behave when they shop and use products or services. It is all about understanding why people buy certain products, what they find attractive and what they don't. It looks at things like their emotions, beliefs, attitudes, and values and how they influence their decisions. Consumer psychologists use market research and focus groups to help companies decide what products or services to offer and how to make sure customers like them. With this information, companies can create advertising campaigns, design packaging and pricing structures, and create store layouts that are more attractive to customers and help them make purchasing decisions.
