Transcript of Types of Diffusion

By Allison Weyman TYPES OF DIFFUSION! What are the four types of diffusion?? Relocation
Stimulus Relocation Diffusion Relocation Diffusion is the spread of an idea through physical movement of people from one place to another. People migrate for several reasons (e.g. political, economic, etc.) and they diffuse their culture (language, religion, and ethnicity) This type of diffusion can help explain why several countries are extremely diverse, through varying languages, diseases, currency, etc. A few examples are:
The spread of Christianity from the middle east to Africa, North America, etc.
Disease cases, such as AIDS, rapidly rising from diffusion. Hierarchical Diffusion is the spread of an idea from persons or nodes of authority or power to other persons or places. Hierarchical Diffusion Hierarchical diffusion can help explain how ideas/innovations diffuse from larger to smaller nodes and vice versa. Some examples of hierarchical diffusion are:
Fashion trends
Music genres, such as rap, hip hop, etc.
Types of dance Hierarchical diffusion is encouraged by modern communication tools, such as computers and messaging systems. Contagious Diffusion is the rapid, widespread diffusion of a characteristic throughout the population. Contagious Diffusion Contagious Diffusion can help explain the spread of a contagious disease; it does not require the permanent relocation of people. Contagious Diffusion is encouraged by the World Wide Web. A few examples of Contagious Diffusion are:
The widespread amount of people with AIDS in America
Hinduism spreading throughout the Indian subcontinent Stimulus Diffusion is the spread of underlying principle, even though a characteristic itself apparently fails to diffuse. Stimulus Diffusion Some examples are:
Advertising: billboards compared to Internet pop-ups
Making selections through a touch screen rather than making selections on a computer through a mouse. Stimulus Diffusion is encouraged by all new technologies, and helps explain how new ideas replace old ideas. And those are the four types of diffusion, Relocation, Hierarchical, Contagious, and Stimulus Mr. Stevens, fourth period The End!
