Grounding in conversation Grounding in communication theory has described conversation as a form of collaborative action. While grounding in communication theory has been applied to mediated communication, the theory primarily addresses face-to-face
conversation. Groups working together will ground their conversations by coming up with common ground or
mutual knowledge. The members will utilize this knowledge in order to contribute to a more efficient dialogue. Grounding criterion is the mutual belief between conversational partners that everyone involved has a clear enough understanding of the concept to move forward. Clark and Schaefer (1989) found that, to reach this state of grounding criterion, groups use three methods of reaching an understanding that they can move forward. • New contribution: A partner moves forward with a new idea, and waits to see if their partner expresses confusion. • Assertion of acceptance: The partner receiving the information asserts that he understands by smiling, nodding, or verbally confirming the other partner. They may also assert their understanding by remaining silent. • Request for clarification: The partner receiving the information asks for clarification. The presentation phase can become complex when meanings are embedded or repairs are made to utterances. An example of a repair is "Do you and your husband have a car," but rather the messier, "now, – um do you and your husband have a j-car".
Acknowledgements refer to
back channel modes of communication that affirm and validate the messages being communicated. Some examples of these include, "uh huh," "yeah," "really," and head nods that act as continuers. They are used to signal that a phrase has been understood and that the conversation can move on.
Relevant next turn refers to the initiation or invitation to respond between speakers, including verbal and nonverbal prompts for
turn-taking in conversation. Questions and answers act as
adjacency pairs, the first part of the conversation is relevant to the second part. Meaning that a relevant utterance needs to be made in response to the question in order for it to be accepted. For example:
Anticipation of what a partner knows There are three main factors that allow speakers to anticipate what a partner knows. • Community co-membership: Members of a group with knowledge in a particular field could use technical jargon when communicating within the group, whereas communicating outside of the group would require them to use layman terms. • Linguistic co-presence: A party in a conversation can use a pronoun to refer to someone previously mentioned in the conversation. • Physical co-presence: If the other parties are also present physically, one could point to an object within their physical environment. Shared visual information also aids anticipation of what a partner knows. For example, when responding to an instruction, performing the correct action without any verbal communication provides an indication of understanding, while performing the wrong action, or even failing to act, can signal misunderstanding. Findings from the paper (Using Visual Information for Grounding and Awareness in Collaborative Tasks), supports previous experiments and show evidence that collaborative pairs perform quicker and more accurately when they share a common view of a workspace. The results from the experiment showed that the pairs completed the task 30–40% faster when they were given shared visual information. The value of this information, however, depended on the features of the task. Its value increased when the task objects were linguistically complex and not part of the pairs‟ shared lexicon. However, even a small delay to the transmission of the visual information severely disrupted its value. Also, the ones accepting the instructions were seen to increase their spoken contribution when those giving the instructions do not have shared visual information. This increase in activity is due to the fact that it is easier for the former to produce the information rather than for the ones giving the instruction to continuously ask questions to anticipate their partners' understanding. Such a phenomenon is predicted by the grounding theory, where it is said that since communication costs are distributed among the partners, the result should shift to the method that would be the most efficient for the pair.
Least collaborative effort The theory of least collaborative effort asserts that participants in a contribution try to minimize the total effort spent on that contribution – in both the presentation and acceptance phases. In exact, every participant in a conversation tries to minimize the total effort spent in that interactional encounter. The ideal utterances are informative and brief. ::A: Um, third one is the guy reading with, holding his book to the left ::B: Okay, kind of standing up? ::A: Yeah. ::B: Okay. offers a conceptualisation which is refashioned slightly by the B before it is agreed on by both. In later repetitions of the task, the expression employed to re-use the agreed conceptualisation progressively became shorter. For example, "the next one looks like a person who's ice skating, except they're sticking out two arms in front" (trial 1) was gradually shortened to "The next one's the ice skater" (trial 4) and eventually became just "The ice skater" in trial 6.
Costs to grounding change The lack of one of these characteristics generally forces participants to use alternative grounding techniques, because the costs associated with grounding change. There is often a trade-off between the costs- one cost will increase as another decreases. There is also often a correlation between the costs. The following table highlights several of the costs that can change as the medium of communication changes. == Grounding in machine-mediated communication ==
