This document defines and explains several key sociological concepts related to collective behavior and social change, including mass hysteria, revisionary movement, reformulation, equilibrium theory, and world-system theory. Equilibrium theory proposes that social change in one area causes change in all other areas as society attempts to regain balance. World-system theory views the spread of capitalism as creating an international division of labor between nations that control production and those that provide cheap labor and raw materials.

2. MASS HYSTERIA
• An unfounded anxiety shared by people who are scattered over a wide geographic
area

3. REVISIONARY MOVEMENT
• A social movement that tries to improve or revise some part of society through
social change

4. REFORMULATION
• The process of adapting borrowed cultural traits

5. EQUILIBRIUM THEORY
• Talcott Parsons's view of social change in which society is likened to a living
organism. Change in one part of the social system produces change in all other
parts as the system attempts to regain balance, or equilibrium

6. WORLD-SYSTEM THEORY
• A theory of modernization, proposed by Immanuel Wallerstein, in which the spread
of capitalism is seen as producing an international division of labor between more-
developed and less-developed nations. According to this view, the more-developed
nations control the factors of production and the less-developed nations serve as
sources of cheap labor and raw materials
