Realism aims to provide a detailed and accurate depiction of reality, focusing on psychological depth and complex characters rather than plot-driven action. Naturalism applies scientific principles to the study of human beings, viewing them as governed by hereditary and environmental forces beyond their control. Regionalism or local color literature features distinctive settings, dialects, and character types particular to a specific geographic region. Both realism and naturalism accumulated precise details to convey slices of reality, while regionalism emphasized remote, nature-dominated locales and limitations they imposed on inhabitants.
