Which of the following elements is NOT considered a key element in communication?

Interactivity is not considered a key element in the basic framework of communication. The central components of communication typically include the message, the sender, the receiver, and often the medium through which the message is transmitted. Filters, such as perceptions and biases, can affect how the message is interpreted, and the role of the receiver is crucial in determining how effectively the message is understood.

In communication theory, interactivity refers more to the dynamic aspect of communication that allows for feedback and participation between the sender and receiver, such as in digital communications or interactive platforms. While interactivity can enhance the communication process by facilitating engagement, it is not a fundamental component like the message or the receiver, which are essential for the process of conveying information. This distinction highlights why interactivity is not classified as one of the primary elements in traditional communication models.
