(2017): Leader social accounts of subordinates' unethical behavior. Examining observer reactions to leader social accounts with moral disengagement language. In: The Journal of applied psychology 102 (10), S. 1448-1461. DOI: 10.1037/apl0000233
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28493747 Abstract: When providing social accounts (Sitkin & Bies, 1993) for the unethical conduct of subordinates, leaders may use language consistent with cognitive strategies described by Bandura (1991, 1999) in his work on moral disengagement. That is, leader's social accounts may reframe or reconstrue subordinates' unethical conduct such that it appears less reprehensible. We predict observers will respond negatively to leaders when they use moral disengagement language within social accounts and, specifically, observers will ostracize these leaders. In addition, we predict that observer moral disengagement propensity moderates this effect, such that the relationship between leaders' use of moral disengagement language within a social account and ostracism is stronger when observer moral disengagement propensity is lower versus higher. Finally, we predict that the reason why observers ostracize the leader is because observers perceive the leader's social account with moral disengagement language as unethical. Thus, perceived leader social account ethicality is predicted to mediate the interaction effect of leader's use of moral disengagement language within social accounts and observer moral disengagement propensity on ostracism. Results from an experiment and field study support our predictions. Implications for theory and practice are discussed. (PsycINFO Database Record

(2015) : Perception of Affective Body Movements in HRI across Age Groups: Comparison between Results from Denmark and Japan: 2015 International Conference on Culture and Computing (Culture Computing): Kyoto, Japan: IEEE, S. 25-32
DOI: https://doi.org/10.1109/Culture.and.Computing.2015.14 Abstract: Social robots are envisioned to move into unrestricted environments where they will be interacting with naive users (in terms of their experience as robot operators). Thus, these robots are also envisioned to exploit interaction channels that are natural to humans like speech, gestures, or body movements. A specificity of these interaction channels is that humans do not only convey task-related information but also more subtle information like e.g. Emotions or personal stance through these channels. Thus, to be successful and not accidentally jeopardizing an interaction, robots need to be able to understand these implicit connotations of the signals (often called social signal processing) in order to generate appropriate signals in a given interaction context. One main application area that is envisioned for social robots is related to elder care, but little is known on how seniors will perceive robots and the signals they produce. In this paper we focus on affective connotations of body movements and investigate how the perception of body movements of robots is related to age. Inspired by a study from Japan, we introduce culture as a variable in the experiment and discuss the difficulties of cross-cultural comparisons. The results show that there are certain age-related differences in the perception of affective body movements, but not as strong as in the original study. A follow up experiment puts the affective body movements into context and shows that recognition rates deteriorate for older participants.

(2014) : Sympathy expression model for the bystander robot in group communication: 2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM): Puerto Princesa, Philippines: IEEE, S. 1-6
DOI: https://doi.org/10.1109/HNICEM.2014.7016192 Abstract: In this paper, we propose a sympathy expression model for a bystander robot that honors the concept of moral emotion. Therefore, we pay attention to the robot that is in a bystander position, which is unrelated to the communication between participants. We propose a sympathy expression model that lets a bystander robot learn the emotional display of others and enables cooperative expressiveness. This model allows the appropriate expressiveness affecting communication of a robot in the position of a bystander. To test it, we assume the interaction of three robots with the emotion generation model using the neural network. Further, we inspect the movement of this model by using a psychology model. As a result, we confirmed the appropriate actions of this model.

(2013): The impact of social context and language comprehension on behaviour. A kinematic investigation. In: PLoS one 8 (12). DOI: 10.1371/journal.pone.0085151
DOI: http://www.ncbi.nlm.nih.gov/pubmed/24376869 Abstract: We investigated whether and how comprehending sentences that describe a social context influences our motor behaviour. Our stimuli were sentences that referred to objects having different connotations (e.g., attractive/ugly vs. smooth/prickly) and that could be directed towards the self or towards "another person" target (e.g., "The object is ugly/smooth. Bring it to you/Give it to another person"). Participants judged whether each sentence was sensible or non-sensible by moving the mouse towards or away from their body. Mouse movements were analysed according to behavioral and kinematics parameters. In order to enhance the social meaning of the linguistic stimuli, participants performed the task either individually (Individual condition) or in a social setting, in co-presence with the experimenter. The experimenter could either act as a mere observer (Social condition) or as a confederate, interacting with participants in an off-line modality at the end of task execution (Joint condition). Results indicated that the different roles taken by the experimenter affected motor behaviour and are discussed within an embodied approach to language processing and joint actions. zitiert von 4
