Expansion diffusion: an innovation or idea that develops in a source area and remains strong there, while also spreading outward to other areas. This can include hierarchical, stimulus, and contagious diffusion. Relocation diffusion: an idea or innovation that migrates into new areas, leaving behind its origin or source of the cultural trait.
Diffusion of innovative ideas. The rate of the individual's decision making process is, therefore, a factor in the innovation's success. [25] [26] The variance between people's responses creates a normal distribution curve. Collar explains, "there is a point on the curve that represents the crux of the diffusion process: the ‘tipping point ...
"Diffusionism", in its original use in the 19th and early 20th centuries, did not preclude migration or invasion.It was rather the term for assumption of any spread of cultural innovation, including by migration or invasion, as opposed "evolutionism", assuming the independent appearance of cultural innovation in a process of parallel evolution, termed "cultural evolutionism".
A variant of the diffusion theory, stimulus diffusion, refers to an element of one culture leading to an invention in another. Contact between cultures can also result in acculturation . Acculturation has different meanings, but in this context refers to replacement of the traits of one culture with those of another, such as what happened with ...

The study of the diffusion of innovations has led to advancements in awareness of three important aspects of social change: the qualities of an innovation which lead to successful diffusion, the effect of peer networking and conversations when it comes to spreading ideas, and the importance of various "user segments" (Robinson). The theory of ...
The drift-diffusion model (DDM) is a well defined [19] model, that is proposed to implement an optimal decision policy for 2AFC. [20] It is the continuous analog of a random walk model. [ 7 ] The DDM assumes that in a 2AFC task, the subject is accumulating evidence for one or other of the alternatives at each time step, and integrating that ...
