Retail psychology is the study of how consumers think, feel, and behave when shopping. It examines factors like store layout, product placement, and pricing strategies that influence purchasing decisions. By understanding these psychological triggers, retailers can create environments that encourage customers to buy more. Key elements of retail psychology include sensory experiences, such as lighting and music, which can affect mood and spending. Additionally, concepts like scarcity and social proof play a role in consumer behavior, as limited availability and positive reviews can drive urgency and trust in products.
