This paper contains a critics to Clark’s Contribution Model, providing applied situations, like communication in an operating room, where the relationship between the presentation and the acceptance phase, as described by Clark, are muddled. Their data contrast with Clark’s model, because the component parts of the sender-receiver model (e.g., environment) may be brought into being through human interaction whithin and upon it. In other words, the boundaries of a contribution may be ambiguous when conversation is tied to an ongoing activity, and/or embodied phenomena. The authors also add that in Clark’s model are also neglected the features of the material and social environment that participants draw upon in making sense of their own and other’s utterances. This paper is in accord with my idea that common ground is something difficult to grasp. However, the author extremise this idea saying that c.g. is not a thing that can be measured, either directly or indirectly.
