Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system. The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product. Adoption means that a person does something differently than what they had previously (i.e., purchase or use a new product, acquire and perform a new behavior, etc.). The key to adoption is that the person must perceive the idea, behavior, or product as new or innovative. It is through this that diffusion is possible. Show
Adoption of a new idea, behavior, or product (i.e., "innovation") does not happen simultaneously in a social system; rather it is a process whereby some people are more apt to adopt the innovation than others. Researchers have found that people who adopt an innovation early have different characteristics than people who adopt an innovation later. When promoting an innovation to a target population, it is important to understand the characteristics of the target population that will help or hinder adoption of the innovation. There are five established adopter categories, and while the majority of the general population tends to fall in the middle categories, it is still necessary to understand the characteristics of the target population. When promoting an innovation, there are different strategies used to appeal to the different adopter categories.

There are five main factors that influence adoption of an innovation, and each of these factors is at play to a different extent in the five adopter categories.
Limitations of Diffusion of Innovation TheoryThere are several limitations of Diffusion of Innovation Theory, which include the following:
This theory has been used successfully in many fields including communication, agriculture, public health, criminal justice, social work, and marketing. In public health, Diffusion of Innovation Theory is used to accelerate the adoption of important public health programs that typically aim to change the behavior of a social system. For example, an intervention to address a public health problem is developed, and the intervention is promoted to people in a social system with the goal of adoption (based on Diffusion of Innovation Theory). The most successful adoption of a public health program results from understanding the target population and the factors influencing their rate of adoption.

According to Marx, individuals create their ideas and identity based on relative autonomy, an expression to define the feeling of freedom given by the ruling class. It implies that a person's identity is determined by the individual's relationship to the means of production.

How baseball is played in Japan reflects the Japanese culture?Japanese baseball is an excellent example of cultural diffusion. While the structure of the game is similar to that of American baseball, the climate and texture of Japanese baseball have been deeply influenced by Japanese cultural values, such as self-discipline, self-sacrifice, politeness, and respect for authority.
Which of the following according to LaRay Barna is one of the barriers to intercultural communication?LaRay M. Barna (1997) has developed a list of six such barriers: anxiety, assuming similarity instead of difference, ethnocentrism, stereotypes and prejudice, nonverbal misinterpretations, and language. His categories of barriers will be used when discussing problems that can arise in intercultural encounters.
