Judee Burgoon and Jerold Hale (1988) contend that two types of expectations exist: pre-interactional and interactional. Pre-interactional expectations include the types of interactional knowleage and skills the communicator possesses before he or she enters a conversation. People do not always understand what it takes to enter and maintain a conversation. Some conversationalists may be very argumentative, for example, and others may be extremely passive. Most people do not expect such extreme behavior in their dialogues with others. Interactional expectations pertain to an individual's ability to carry our the interaction itself. Most people expect others to maintain appropriate conversational distance. In addition, in communicating with others, listening behaviors such as prolonged eye contact are frequently expected. These and host of others behaviors are important to consider when examining the role of expectations before and during an interaction.
