Communication apprehension is the level of anxiety triggered by the real or anticipated communication act, as defined by McCroskey. It is connected to the idea of judgment from the audience, and self-image. Communication apprehension, CA, can cause a variety of involuntary responses such as 'stomach butterflies' which is your body shutting the digestive system down and going into the “fight-or-flight” response, shaking, nausea, sweating, forgetting the information, among many others. The term communication apprehension is usually connected with 'stage fright'; however, this response is not necessarily connected with a delivery on a stage or in front of a large audience. This anxiety can be caused by any of the four forms of communication: interpersonal, group, public, and mass communication. The most common and reliable test used to measure an individual’s CA level when exposed to these forms of communication is called the Personal Report of Communication Apprehension, also known as the PRCA-24 test, and it follows a survey format.
