This paper investigates the effects of relative position and proxemics in the engagement process involved in Human-Robot collaboration. We evaluate the differences between two experimental placement conditions for an autonomous robot in a collaborative task with a user across two different types of robot behaviours. The study evaluated placement and behaviour types around a touch table with 80 participants by measuring gaze, smiling behaviour, distance from the task, and finally electrodermal activity. Results suggest an overall user preference and higher engagement (...) rates with the helpful robot in the frontal position. We discuss how behaviours and position of the robot relative to a user may affect user engagement and collaboration, in particular when the robot aims to provide help via socio-emotional bonding.

The situation-dependent lateralization of sympathetic electrodermal arousal during real-life stress (Picard, Fedor, & Ayzenberg, 2016) may challenge a unitary notion of arousal, and call into question the practice of unilateral electrodermal recording, but there are broader implications. Here we consider a potential relationship between stress-induced lateralized shifts in electrodermal activity, and a theory concerning lateralized emotion-induced cardiac arrhythmia.

We respond to the commentaries of Critchley and Nagai, Mendes, Norman, Sabatinelli, and Richter. We agree that a theory needs to make predictions and we elaborate on the predictions we made so far. We do not agree that arousal has to have a precise definition in order to present theory about it; however, we do provide concrete answers to questions raised about multiple arousal theory.

The current paper investigates the value and application of a range of physiological and neuroscientific techniques in applied marketing research and consumer science, highlighting new insights from research in social psychology and neuroscience. We review measures of sweat secretion, heart rate, facial muscle activity, eye movements, and electrical brain activity, using techniques including skin conductance, pupillometry, eyetracking, and magnetic brain imaging. For each measure, after a brief explanation of the underlying technique, we illustrate concepts and mechanisms that the measure allows (...) researchers in marketing and consumer science to investigate, with a focus on consumer attitudes and behavior. By providing reviews on recent research that applied these methods in consumer science and relevant related fields, we also highlight methodological and theoretical strengths and limitations, with an emphasis on ecological validity. We argue that the inclusion of physiological and neuroscientific techniques can advance consumer research by providing insights into the often unconscious mechanisms underlying consumer behavior. Therefore, such technologies can help researchers and marketing practitioners understand the mechanisms of consumer behavior and improve predictions of consumer behavior. (shrink)

Recently, social neurosciences have been interested in the investigation of neurophysiological responses related to the experience of positive emotions, such as gratitude, during social interactions. Specifically, the aim of the present research was to investigate whether gratitude related to gift exchange could favor cooperative behavior and bond construction, by improving behavioral and autonomic responsivity. At this regard, the autonomic synchronization and behavioral performance of 16 friends coupled in dyads were recorded during a joint attentional task. Gift exchange could be occurred (...) either at the beginning or in the middle of the task. For the recording of simultaneous autonomic activity [heart rate and skin conductance level ], a hyperscanning biofeedback paradigm was used. Intra-subjective analysis showed an increase in behavioral [accuracy ] and autonomic responses when the gift exchange took place at the beginning of the task rather than in the middle. Moreover, inter-subjective analysis revealed an increase in behavioral performance and greater autonomic synchronization of HR index. The present research, therefore, shows how gratitude and trust experienced following gift exchange can modify participants’ reactions by creating a shared cognition and the adoption of joint strategies.

The concept of psychophysiological arousal as a component of emotional behavior has a long history, but has not attracted the research attention paid to valence in the burgeoning field of affective neuroscience. The potency of emotional stimuli is often poorly balanced in studies designed to assess appetitive and aversive stimulus processing, and thus I applaud Picard and colleagues’ choice to highlight the arousal dimension of emotional behavior. Any attempt to understand the nature of human emotion must carefully balance the evocative (...) impact of appetitive and aversive processes. By focusing on the contribution of arousal to emotional processing, Picard advances this goal. In this comment I suggest methodological and conceptual refinements that may help to strengthen the multiple arousal theory perspective. (shrink)

Multiple arousal theory suggests that there is more than one arousal system and that the activity of the multiple arousal systems can be observed using electrodermal measures at various body sites. The ideas expressed by multiple arousal theory are interesting but they do not constitute a theory. The absence of a specific definition of arousal and the lack of testable predictions prevent multiple arousal theory from constituting a useful theoretical framework for focussed empirical research.

Picard, Fedor, and Ayzenberg (2016) provide a review of the existing literature on the relationship between electrodermal activity (EDA) and affective processes and present data from a number of studies suggesting strong lateralization in EDA reactivity to emotion. As the authors note, their manuscript extends previous work suggesting the concept of arousal is more complex than previously thought, and they provide a framework for interpreting such complexities within the context of a multiple arousal theory.
