Which are the four main types of cultural diffusion?

• A. Contagious, expansion, relocation, hierarchical
• B. Contagious, hierarchical, relocation, diffusion
• C. Contagious, hierarchical, relocation, stimulus
• D. Contagious, hierarchical, stimulus, relocation

Answer: (D)

How cultural traits spread through places follows distinct diffusion patterns. The four main types are contagious diffusion, hierarchical diffusion, relocation diffusion, and stimulus diffusion. Contagious diffusion describes ideas or practices spreading quickly through close contact and interaction, like a fashion trend or a viral meme that catches on broadly. Hierarchical diffusion involves movement from larger or more influential centers to smaller places or groups, such as a trend first appearing in a big city and then spreading outward. Relocation diffusion happens when people migrate and carry their cultural traits with them, introducing new cuisines, languages, or customs to new regions. Stimulus diffusion occurs when an underlying idea spreads but is adapted or repackaged to fit local conditions, like a global concept being altered to suit local tastes or practices.

Because these four categories cover the standard ways cultural traits diffuse, an option listing contagious, hierarchical, relocation, and stimulus diffusion (in any order) is correct.
