The study investigates two different ways of guiding the addressee of an explanation - an explainee, through action demonstration: contrastive and non-contrastive. Their effect was tested on attention to specific action elements (goal) as well as on event memory. In an eye-tracking experiment, participants were shown different motion videos that were either contrastive or non-contrastive with respect to the segments of movement presentation. Given that everyday action demonstration is often multimodal, the stimuli were created with re- spect to their visual and verbal presentation. For visual presentation, a video combined two movements in a contrastive (e.g., Up-motion following a Down-motion) or non-contrastive way (e.g., two Up-motions following each other). For verbal presentation, each video was combined with a sequence of instruction descriptions in the form of negative (i.e., contrastive) or assertive (i.e., non-contrastive) guidance. It was found that a) attention to the event goal increased for this condition in the later time window, and b) participants’ recall of the event was facilitated when a visually contrastive motion was combined with a verbal contrast.

Such alignment has been proposed to be automatic and the basis for communicating successfully. Recent research on human-computer dialog promotes a mediated communicative design account of alignment according to which the extent of alignment is influenced by interlocutors' beliefs about each other. Our work aims at adding to these findings in two ways. (a) Our work investigates alignment of manual actions, instead of lexical choice. (b) Participants interact with the iCub humanoid robot, instead of an artificial computer dialog system. Our results confirm that alignment also takes place in the domain of actions. We were not able to replicate the results of the original study in general in this setting, but in accordance with its findings, participants with a high questionnaire score for emotional stability and participants who are familiar with robots align their actions more to a robot they believe to be basic than to one they believe to be advanced. Regarding alignment over the course of an interaction, the extent of alignment seems to remain constant, when participants believe the robot to be advanced, but it increases over time, when participants believe the robot to be a basic version.","lang":"eng"}],"publication":"International Journal of Social Robotics","keyword":["learning","Human-robot interaction","Alignment","Robot social","Action understanding"],"language":[{"iso":"eng"}],"year":"2015","issue":"2","title":"Alignment to the Actions of a Robot","publisher":"Springer-Verlag","date_created":"2020-06-24T13:01:06Z","status":"public","type":"journal_article","_id":"17189","user_id":"14931","department":[{"_id":"749"}],"citation":{"chicago":"Vollmer, Anna-Lisa, Katharina Rohlfing, Britta Wrede, and Angelo Cangelosi. “Alignment to the Actions of a Robot.” International Journal of Social Robotics 7, no. 2 (2015): 241–52. https://doi.org/10.1007/s12369-014-0252-0.","ieee":"A.-L.
