“…We also find huge variation between participants with regards to how they refer to Pepper, and perceived feelings of connection towards the system. Based on current and other recent findings (e.g., Henschel & Cross, 2020), we would also argue that measures such as the Godspeed Liking scale are overly specificfocussing on social liking and neglecting other forms of liking in the process. In addition to advising the use of embodied human-robot interaction for probing other cognitive measures of social perception, such as gaze cueing (e.g., Kompatsiari et al, 2018;2019; see also Henschel, Hortensius & Cross, 2020), we also suggest that future studies consider adding more might reveal about their research questions and robotic system of interest.…”

“…One of the factors that researchers are examining in terms of building stronger bonds between humans and robots is interpersonal synchrony (e.g., Henschel & Cross, 2020;Lehmann et al, 2015, Mörtl, Lorenz, & Hirche, 2014. Interpersonal synchrony refers to the overlap of movement/sensation in time or form (for example, when we tap in sync, compared to out of sync, with another person; Hove & Risen, 2009).…”

“…In an attempt to increase the liking and acceptance of robotic systems, researchers have experimentally-induced movement synchrony between individuals and robots (e.g., Henschel & Cross, 2020;Lehmann et al, 2015, Mörtl, Lorenz, & Hirche, 2014. To do so, the movement of the participant is monitored, and this information is relayed to the robotic system in real time.…”

“…However, not all studies that have manipulated interpersonal synchrony between humans and robots report positive impacts on participants' prosociality toward robots. In an experiment using the Pepper robot, Henschel and Cross (2020) found that when participants completed a synchronous compared to asynchronous drawing task with a robot, this had no effect on perceived likability of the robot, nor how many questions the participants asked the social robot (another type of prosocial behaviour termed "social motivation"). The lack of significant findings raises questions about the robustness of synchrony manipulations, and the authors also suggest that subtlety of the manipulation and the taskoriented nature of the task might further dilute impacts of synchrony manipulations (Henschel & Cross, 2020).…”

“…Given prior work in this domain that has led to the development of a number of relevant questionnaires, future work might wish to explore in a more systematic way whether participant responses to one or several of these questionnaires hold predictive value for participants' susceptibility to prosociality measures (c.f. Henschel & Cross, 2020). Anthropomorphism is proposed to be of huge importance for bonding between humans and animals (Mithen, 1996), so by conducting follow-up work probing anthropomorphic perceptions and tendencies more sensitively, it might be possible to identify populations which are more or less likely to bond with, and benefit from robotic agents, over the long term.…”

Robots are being designed to alleviate the burden of social isolation and loneliness, particularly for older adults for whom these issues are more widespread. While good intentions underpin these developments, the reality is that many of these robots are abandoned within a short period of time. To encourage the longer-term use and utility of such robots, researchers are exploring ways to increase robot likability and facilitate attachment. Results from experimental psychology suggest that interpersonal synchrony (the overlap of movement/sensation between two agents) increases the extent to which people like one another. To investigate the possibility that synchrony could facilitate people’s liking towards a robot, we undertook a between-subjects experiment in which participants interacted with a robot programmed to illuminate at the same rate, or 20% slower, than their heart rate. To quantify the impact of cardio-visual synchrony on prosocial attitudes and behaviours toward this robot, participants completed self-report questionnaires, a gaze-cueing task, and were asked to strike the robot with a mallet. Contrary to hypotheses, results revealed no differences in self-reported liking of the robot, gaze cueing effects, or the extent to which participants hesitated to hit the robot between the synchronous and asynchronous groups. The qualitative data collected in semi-structured interviews provided rich insights, though, and call into question the use of the broad “Likability” measurement, and the appropriateness of the ‘hesitance to hit’ paradigm as a measure of attachment to a robotic system.

Gradual Rhythm Change of a Drumming Robot Enhances the Pseudosense of Leading in Human–Robot Interactions

et al. 2022

In order to achieve symbiosis between humans and social robots, it is not enough to simply design a robot with excellent functionality, but it is necessary to give humans a friendly impression of the robot. Rhythmic synchronization is the foundation of social interaction and unity, and it is expected that research on synchronization between humans and robot will contribute to the design theory of robot that can build intimate relationships with humans. Specifically, the sense of leading a rhythm evokes a pleasant emotion. If a communication robot is behaviorally synchronized with humans, a strong sense of unity with the robot could occur in keeping with their sense of leading. However, in rhythmic interactions, having the sense of leading the rhythm often differs from the actual rhythm leading. We conducted three kinds of experiments to examine whether a pseudosense of leading occurred in human-robot or human-human drumming interactions. At the experiment 1, we used an interaction task of human-robot drumming to examine whether participants experienced a strong sense of leading when interacting with a robot drumming with gradual rhythm fluctuations and whether the sense of leading the rhythm induced a positive impression of the robot. As a result, we found that a pseudosense of leading the rhythm and the pleasant emotion of drumming occurred even from the artificial robot's rhythm, notably when the rhythm of the robot changed gradually. At the experiment 2, we also showed that the pseudosense of leading was not likely to occur in the drumming between humans. Finally, at the experiment 3, we found that the pseudosense of leading would induce anthropomorphic impressions of the robots. These findings may contribute to designing interactive robots' rhythmic behavior to realize symbiosis between humans and robots.INDEX TERMS pseudosense of leading, drumming interaction, anthropomorphic impression.

Background: Robots are being designed to alleviate the burden of social isolation and loneliness, particularly among older adults for whom these issues are more widespread. While good intentions underpin these developments, the reality is that many of these robots are abandoned within a short period of time. To encourage the longer-term use and utility of such robots, researchers are exploring ways to increase robot likeability and facilitate attachment. Results from experimental psychology suggest that interpersonal synchrony (the overlap of movement/sensation between two agents) increases the extent to which people like one another. Methods: To investigate the possibility that synchrony could facilitate people’s liking towards a robot, we undertook a between-subjects experiment in which participants interacted with a robot programmed to illuminate at the same rate, or 20% slower, than their heart rate. To quantify the impact of cardio-visual synchrony on prosocial attitudes and behaviors toward this robot, participants completed self-report questionnaires, a gaze-cueing task, and were asked to strike the robot with a mallet. Results: Contrary to pre-registered hypotheses, results revealed no differences in self-reported liking of the robot, gaze cueing effects, or the extent to which participants hesitated to hit the robot between the synchronous and asynchronous groups. Conclusions: The quantitative data described above, as well as qualitative data collected in semi-structured interviews, provided rich insights into people’s behaviours and thoughts when socially engaging with a humanoid social robot, and call into question the use of the broad “Likeability” measurement, and the appropriateness of the ‘hesitance to hit’ paradigm as a measure of attachment to a robotic system.
