Document Summary
Key concepts: rates of adoption create an s-shaped curve. Four elements of diffusion theory (doi: diffusion: the process by which an innovation is communicated through certain channels over time among members of a social system. Element 2: communication channels: media: formal channel; includes tv, radio, internet, and print media, awareness knowledge: lets people know that an innovation exists. Interpersonal channel: informal channel; includes people"s interactions: subjective evaluation: personal favorable opinion, homophily: any two people are very similar in their views, perceptions, and beliefs within their larger social system. Stage 1: knowledge: awareness knowledge: knowledge of the existence of the innovation, how-to knowledge: knowledge regarding how the innovation is to be used, principles knowledge: knowledge about the principles that underlie the innovation; how the innovation works. Stage 2: persuasion: form a strong and positive attitude toward the innovation, expected consequences of adopting the innovation.
