We propose a simple model of grounded affect and kinesic expression before presenting the qualitative findings of an exploratory study (N=9), during which participants were interviewed after watching expressive and non-expressive hexapod robots perform different {\textquoteleft}scenes{\textquoteright}. A summary of these interviews is presented and a number of emerging themes are identified and discussed. Whilst our findings suggest that the expressive robot did not evoke significantly greater empathy or altruistic intent in humans than the control robot, the expressive robot stimulated greater desire for interaction and was also more likely to be attributed with emotion.}, doi = {10.1007/978-3-030-63486-5_26}, url = {https://link.springer.com/chapter/10.1007/978-3-030-63486-5_26}, author = {Hickton, Luke and Lewis, Matthew and Lola Ca{\~n}amero}, editor = {Abdelkhilick Mohammad and Xin Dong and Matteo Russo} } @inproceedings {2019, title = {The Effects of Affective Social Bonds on the Interactions and Survival of Simulated Agents}, booktitle = {ACII2019 Workshop on Social Emotions, Theories and Models (SE-THEMO)}, year = {2019}, note = {Download (or Download accepted version)}, month = {09/2019}, pages = {374{\textendash}380}, address = {Cambridge, UK}, abstract = {The formation and maintenance of affective social bonds plays a key role in the well-being of social agents. Oxytocin has been correlated with social partner preference, and it is hypothesised to influence prosocial behaviours. In this paper, we investigate the effects of modulating the preference of affective social bond partners through oxytocin during decisions related to food-sharing and grooming, in a society of simulated agents with different dominance ranks. Our results show survival benefits for agents with affective social bonds across a number of groups with different bond combinations. We observe a number of emergent social behaviours and suggest that our results bear some similarity with behaviors observed in biological agents.}, doi = {10.1109/ACIIW.2019.8925031}, url = {https://ieeexplore.ieee.org/abstract/document/8925031}, author = {Imran Khan and Lewis, Matthew and Lola Ca{\~n}amero} } @inproceedings {3, title = {An Embodied AI Approach to Individual Differences: Supporting Self-Efficacy in Diabetic Children with an Autonomous Robot}, booktitle = {Proc. 7th International Conference on Social Robotics (ICSR-2015)}, series = {Lecture Notes in Computer Science}, year = {2015}, note = {Download (or Download authors{\textquoteright} draft)}, pages = {401{\textendash}410}, publisher = {Springer International Publishing}, organization = {Springer International Publishing}, address = {Paris}, abstract = {In this paper we discuss how a motivationally autonomous robot, designed using the principles of embodied AI, provides a suitable approach to address individual differences of children interacting with a robot, without having to explicitly modify the system.

We have specifically framed our study in three variants of dynamic three-resource action selection environment. The challenges posed by these environments include: moving resources, temporal and increasing unavailability of resources, and cyclic changes in type and availability of resources related to cyclic environmental changes.}, doi = {10.7551/978-0-262-31709-2-ch073}, url = {https://www.mitpressjournals.org/doi/abs/10.1162/978-0-262-31709-2-ch073}, author = {Lones, John and Lola Ca{\~n}amero and Lewis, Matthew} }
