Interaction among humans does not always proceed without errors; situations might happen in which a wrong word or attitude can cause the partner to feel uneasy. However, humans are often very sensitive to these interaction failures and may be able to fix them. Our research aims to endow robots with the same skill. Thus the first step, presented in this short paper, investigates to which extent a humanoid robot can impact someone's Comfortability [11] in a realistic setting. To capture natural reactions, a set of real interviews performed by the humanoid robot iCub (acting as the interviewer) were organized. The interviews were designed in collaboration with a journalist from the press office of our institution and are meant to appear on the official institutional online magazine. The dialogue along with fluent human-like robotic actions were chosen not only to gather information about the participants' personal interests and professional career, necessary for the magazine column, but also to influence their Comfortability. Once the experiment is completed, the participants' self-report and spontaneous reactions (physical and physiological cues) will be explored to tackle the way people's Comfortability may be manifested through non-verbal cues and impacted by the humanoid robot.

Adaptive behaviour is essential for robots to establish natural social interactions with humans. It is grounded and develops from an adaptive perception of the environment and the other agents. At the intersection of social and cognitive robotics, this paper theorises interpretation as a fundamental instrument to provide such skills to robots. First, the hermeneutical circle of context and experience is described as a core element of adaptivity in human perception. Second, the process of interpretation/contextualisation is presented through two different but complementary levels. Finally, in a dialogue with the current developments in social robots, the paper brings to attention some problems and possibilities on the topic.
Visual perception of space and time has been shown to rely on context dependency, an inferential process by which the average magnitude of a series of stimuli previously experienced acts as a prior during perception. This article aims to investigate the presence and evolution of this phenomenon in early aging. Two groups of participants belonging to two different age ranges (Young Adults: average age 28.8 years old; Older Adults: average age 62.8 years old) participated in the study performing a discrimination and a reproduction task, both in a spatial and temporal conditions. In particular, they were asked to evaluate lengths in the spatial domain and interval durations in the temporal one. Early aging resulted to be associated to a general decline of the perceptual acuity, which is particularly evident in the temporal condition. The context dependency phenomenon was preserved also during aging, maintaining similar levels as those exhibited by the younger group in both space and time perception. However, the older group showed a greater variability in context dependency among participants, perhaps due to different strategies used to face a higher uncertainty in the perceptual process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
