ESSENTIAL KNOWLEDGE IMP-3. A. 1 • Relocation and expansion-including contagious, hierarchical, and stimulus expansion-are types of diffusion • Relocation Diffusion: A form of diffusion where the ideas being diffused are transmitted by their carriers as they migrate to new areas • Expansion Diffusion: The spread of an idea through a population in a way that the number of those influenced becomes continuously larger. Includes contagious, hierarchical, and stimulus diffusion. • Contagious: Transmission of a phenomenon through close contact with nearby places, like diseases. • Hierarchical: An idea spreads by passing first among the most connected individuals, then spreading to other individuals (large connected cities to other large connected cities, then to smaller connected cities) • Reverse Hierarchical: Diffusion up a hierarchy, such as from a little city to a big one. • Stimulus: A form of diffusion in which a cultural adaptation is created as a result of the introduction of a cultural trait from another place. In other words, it is the spreading of an underlying principle of an idea when the idea as a whole cannot spread to a
