Evaluating Semantic Co-creation by Using a Marker as a Linguistic Constraint Tool in Shared Cognitive Representation Models

Semantic co-creation occurs in the process of communication between two or more people, where human cognitive representation models of the topic of discussion converge. The use of linguistic constraint tools (for example a shared marker) enable participants to focus on communication, improving communicative success. Recent results state that the best communicative success can be achieved if two users can interact in a restricted way, so called team focused interaction hypothesis. Even though the advantage of team focused interaction sounds plausible, it needs to be noted that previous studies enforce the constraint usage. Our study aims at investigating the advantage of using shared markers as a linguistic constraint tool in semantic co-creation, while moving them becomes optional. In our experimental task, based on a shared geographic map as a cognitive representation model, the two participants have to identify a target location, which is only known to a third participant. We assess two main factors, the teams’ use of a shared marker and the two complexity levels of the cognitive representation model. We had hypothesized that sharing a marker should improve communicative success, as communication is more focused. However, our results indicated no general benefit by using a marker as well as team interaction, itself. Our results suggest that the use of a shared marker is an efficient linguistic constraint at higher levels of complexity of the cognitive representation than those tested in our study. Based on this consideration, the team focused interaction hypothesis should be further developed to include a control parameter for the perceived decision complexity of the cognitive representation model.
