Rather than having one sender, one message, and one receiver, this model has two sender-receivers who exchange messages. The inclusion of a feedback loop also leads to a more complex understanding of the roles of participants in a communication encounter. For example, your instructor may respond to a point you raise during class discussion or you may point to the sofa when your roommate asks you where the remote control is. Feedback includes messages sent in response to other messages. Rather than illustrating communication as a linear, one-way process, the interaction model incorporates feedback, which makes communication a more interactive, two-way process. The interaction model of communication describes communication as a process in which participants alternate positions as sender and receiver and generate meaning by sending messages and receiving feedback within physical and psychological contexts (Schramm, 1997). The radio announcer doesn’t really know if you receive their message or not, but if the equipment is working and the channel is free of static, then there is a good chance that the message was successfully received. The sender is the radio announcer who encodes a verbal message that is transmitted by a radio tower through electromagnetic waves (the channel) and eventually reaches your (the receiver’s) ears via an antenna and speakers in order to be decoded. Think of how a radio message is sent from a person in the radio studio to you listening in your car. You are left to presume that the receiver either successfully receives and understands the message or does not. Although the receiver is included in the model, this role is viewed as more of a target or endpoint rather than part of an ongoing process. This model focuses on the sender and message within a communication encounter. The transmission model of communication describes communication as a linear, one-way process in which a sender intentionally transmits a message to a receiver (Ellis & McClintock, 1990). If your roommate has headphones on and is engrossed in a video game, you may need to get their attention by waving your hands before you can ask them about dinner. While communication can be sent and received using any sensory route (sight, smell, touch, taste, or sound), most communication occurs through visual (sight) and/or auditory (sound) channels. Encoded messages are sent through a channel, or a sensory route, on which a message travels to the receiver for decoding. Of course, you don’t just communicate verbally-you have various options, or channels, for communication. Do you want to get pizza tonight?” As your roommate receives the message, they decode your communication and turn it back into thoughts to make meaning. For example, you may realize you’re hungry and encode the following message to send to your roommate: “I’m hungry. Decoding is the process of turning communication into thoughts. The audience then ‘decodes’, or interprets, the message for themselves. The encoder should also take into account any ‘noise’ that might interfere with their message, such as other messages, distractions, or influences. The level of conscious thought that goes into encoding messages may vary. The encoder uses a ‘medium’ to send the message - a phone call, email, text message, face-to-face meeting, or other communication tools. As represented in the video below, the encoder must determine how the message will be received by the audience, and make adjustments so the message is received the way they want it to be received.Įncoding is the process of turning thoughts into communication. The encoder is the person who develops and sends the message. In basic terms, humans communicate through a process of encoding and decoding.
