  2. Source–message–channel–receiver model of communication

    en.wikipedia.org/wiki/Source–message–channel...

    One of the subelements of the message is its code. [8] In communication theory, a code is a sign system to express information or a system of rules to convert information from one form into another. [49] Berlo defines code as "any group of symbols that can be structured in a way that is meaningful to some person".

  3. Models of communication - Wikipedia

    en.wikipedia.org/wiki/Models_of_communication

    Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.

  4. Extended parallel process model - Wikipedia

    en.wikipedia.org/wiki/Extended_parallel_process...

    Two main components of large-scale public messaging that induce behavioural change are fear appeals and fear appraisals. Fear appeals are specifically designed to elicit fear and nudge individuals to adapt to the recommendations in the message. They find their use in public health campaigns and political adverts, and are designed to fit three ...

  5. Schramm's model of communication - Wikipedia

    en.wikipedia.org/wiki/Schramm's_model_of...

    Schramm's model of communication was published by Wilbur Schramm in 1954. It is one of the earliest interaction models of communication. [1] [2] [3] It was conceived as a response to and an improvement over earlier attempts in the form of linear transmission models, like the Shannon–Weaver model and Lasswell's model.

  7. Lasswell's model of communication - Wikipedia

    en.wikipedia.org/wiki/Lasswell's_model_of...

    Sapienza et al. argue against this view that Lasswell's model is not a linear transmission model since Lasswell also discusses two-way communication in another paper. [2] Another argument in favor of this objection is that the effect discussed by Lasswell may be understood as some form of feedback. [24]

  8. Communication disorder - Wikipedia

    en.wikipedia.org/wiki/Communication_disorder

    Gleason (2001) defines a communication disorder as a speech and language disorder which refers to problems in communication and in related areas such as oral motor function. The delays and disorders can range from simple sound substitution to the inability to understand or use one's native language. [3]

  9. Shannon–Weaver model - Wikipedia

    en.wikipedia.org/wiki/Shannon–Weaver_model

    Shannon and Weaver distinguish three types of problems of communication: technical, semantic, and effectiveness problems. They focus on the technical level, which concerns the problem of how to use a signal to accurately reproduce a message from one location to another location. The difficulty in this regard is that noise may distort the signal.
