Attitude change refers to the process by which a person's feelings, beliefs, or evaluations about a particular subject, person, or issue shift over time. This change can occur due to various factors, including new information, personal experiences, or social influences. For example, an individual may develop a more positive attitude towards climate change after learning about its impacts and solutions. Several psychological theories explain how attitude change occurs. The Elaboration Likelihood Model suggests that people can change their attitudes through two routes: the central route, which involves careful consideration of arguments, and the peripheral route, which relies on superficial cues. Understanding these processes can help in areas like marketing and education.
