Major psychological processes that influence consumer responses to marketing include motivation, perception, learning, and memory. Motivation is driven by needs and wants at both conscious and unconscious levels. Marketers aim to position brands to appeal to psychological motives. Perception is how consumers select, organize, and interpret information to understand the world. Learning changes behavior through experiences, allowing marketers to build demand by associating products with strong desires. Memory is a network of stored information and connections that marketers can influence.
