Understanding choice utterances

When individuals offer choices, they intend them to be mandatory (requiring action) or permissive (not requiring action), and they intend them to be open (allowing the choice of both options) or closed (not allowing the choice of both options). In two studies subjects were presented with sets of syntactically equivalent disjunctive sentences with varying content designed to represent four patterns of permitted choice. The research indicates that individuals distinguish four distinct uses of “or” in deontic contexts, and that individuals more often judge choices as mandatory than permissive. The research also compared responses to questions about choice giver intent and receiver choice. The data indicate that when judging intent, individuals are inclined to understand some choices to be permissive. However, when judging what action they might take as choice receiver, subjects tend to regard action to be mandatory. It appears that although people have some facility in assessing a permission giver's intent, they often apply a more restrictive rule to themselves than is required by the choice giver.     

Transformed Social Interaction,Augmented Gaze,and Social Influence in Immersive Virtual Environments

Immersive collaborative virtual environments (CVEs) are simulations in which geographically separated individuals interact in a shared, three‐dimensional, digital space using immersive virtual environment technology. Unlike videoconference technology, which transmits direct video streams, immersive CVEs accurately track movements of interactants and render them nearly simultaneously (i.e., in real time) onto avatars, three‐dimensional digital representations of the interactants. Nonverbal behaviors of interactants can be rendered veridically or transformed strategically (i.e., rendered nonveridically). This research examined augmented gaze, a transformation in which a given interactant's actual head movements are transformed by an algorithm that renders his or her gaze directly at multiple interactants simultaneously, such that each of the others perceives that the transformed interactant is gazing only at him or her. In the current study, a presenter read a persuasive passage to two listeners under various transformed gaze conditions, including augmented gaze. Results showed that women agreed with a persuasive message more during augmented gaze than other gaze conditions. Men recalled more verbal information from the passage than women. Implications for theories of social interaction and computer‐mediated communication are discussed.
