Physical and Mental Activities

The Physical and Mental Activities hierarchy contains descriptors for activities ranging from single actions to complex sets of physical and mental pursuits. Mental activities are those performed entirely or primarily with the brain. Physical activities are those performed with other parts of the body or the body as a whole. Relation to Other Hierarchies: Descriptors for processes performed physically on or with materials or objects (e.g., carving) are found in the Processes and Techniques hierarchy. Descriptors for organizational, administrative, or intellectual activities conducted to achieve specific purposes (e.g., analysis) are found in the Functions hierarchy. Descriptors denoting occasions, including those when activities in this hierarchy might take place (e.g.g., sailing, basketball) or are always dependent for their occurrence on a clearly defined set of circumstances (e.g., races) appear in the Events hierarchy.
