Gestalt Theory is a psychological approach that emphasizes understanding the mind and behavior as a whole, rather than by breaking them down into smaller parts. It originated in the early 20th century and focuses on how people perceive and interpret visual information. The theory suggests that our brains organize sensory input into meaningful patterns and forms, which helps us make sense of the world around us. Key principles of Gestalt Theory include concepts like figure-ground perception, similarity, and proximity. These principles explain how we group elements in our environment to create a coherent perception. For example, we tend to see objects that are close together as part of a group, which influences how we understand visual scenes.
