Associated Concepts

The Associated Concepts hierarchy consists of descriptors for concepts and phenomena relating to a wide range of subjects, some of which are not within the primary scope of the AAT, such as philosophical concepts, but which affect subjects within that scope. Relation to Other Hierarchies: Descriptors for branches of learning and areas of specialization, as well as professions and professional specialties, (e.g., history) are found in the Disciplines hierarchy, while concepts associated with these disciplines (e.g., positivism) appear here. Descriptors for styles and for art and architecture movements (e.g., Neoclassical, Impressionist) are found in the Styles and Periods hierarchy, while forms of expression (e.g., abstraction) and broad categories of art and architecture which are not specific to a given people or period (e.g., organic architecture, street art) appear here.
