“…Previous studies on HERs show that prefrontal cortex activity is related to selfconsciousness processing in the default network (Azzalini et al, 2019). Various tests showed that locking EEG to heartbeats is necessary to find distinctions between patients, revealing the existence of a possible auditory-cardiac synchrony (Pérez et al, 2021;Pfeiffer and Lucia, 2017). This study gives evidence that HERs detect auditory conscious perception, in addition…”

“…Considering that brain-heart interactions have demonstrated to be involved in consciousness (Azzalini et al, 2019;Candia-Rivera et al, 2021a;Pérez et al, 2021;Raimondo et al, 2017) we analyzed neural responses to heartbeats during processing of auditory irregularities to characterize DOC. During the global effect, differences appear between MCS/UWS in HERs on the electrodes located in frontal and central regions in both hemispheres.…”

“…We recently showed that cognitive modulation of the heart-cycle (Pérez et al, 2021;Raimondo et al, 2017) on one hand, and heartbeat-evoked responses (HERs) in resting state on the other hand (Candia-Rivera et al, 2021a) may capture residual signs of consciousness in postcomatose patients in resting-state, suggesting that HERs might convey state-of-consciousness relevant information about how the brain responds to body-related stimuli. Empirical and theoretical research on consciousness supports that bodily and interoceptive processes may shape exteroceptive and metacognitive awareness, and vice versa (Nikolova et al, 2021).…”

ObjectivesDetermine if contextual processing of auditory regularities (local-global paradigm) modulate the heartbeat-evoked responses (HERs), and if these modulations may provide complementary information to the auditory related potentials to facilitate the diagnose of patients with disorders of consciousness (DOC).MethodsDOC patients underwent the local-global paradigm to evaluate the cognitive processing of short/long term–auditory regularities. High-density EEG was recorded to evaluate HERs in local, global and overall conditions.ResultsThe global effect triggers higher HERs, as well as overall higher HER variance appears in minimally conscious patients. The variance and amplitude effects were uncorrelated, indicating different cognitive processes.DiscussionOur results corroborate previous findings on HER variance, a marker able to separate DOC without specific stimulations. HER modulations in response to global auditory irregularities represents a novel neural signature of consciousness access, which may facilitate the bedside diagnosis of state of consciousness with more affordable options to neuroimaging methods.

“…In other words, when an individual's brain response is similar to other people engaging with a piece of media, then they are likely to be more engaged. This effect is comparable to the finding that, across a group of independent people, heart rates rise and fall in synchrony to a verbal story, but only during engaged attention (Pérez et al, 2021 ). Dauer et al ( 2021 ) found that the ISC predicted continuously reported individual listener engagement while listening to Steve Reich's Piano Phase .…”

Resonance, a powerful and pervasive phenomenon, appears to play a major role in human interactions. This article investigates the relationship between the physical mechanism of resonance and the human experience of resonance, and considers possibilities for enhancing the experience of resonance within human–robot interactions. We first introduce resonance as a widespread cultural and scientific metaphor. Then, we review the nature of “sympathetic resonance” as a physical mechanism. Following this introduction, the remainder of the article is organized in two parts. In part one, we review the role of resonance (including synchronization and rhythmic entrainment) in human cognition and social interactions. Then, in part two, we review resonance-related phenomena in robotics and artificial intelligence (AI). These two reviews serve as ground for the introduction of a design strategy and combinatorial design space for shaping resonant interactions with robots and AI. We conclude by posing hypotheses and research questions for future empirical studies and discuss a range of ethical and aesthetic issues associated with resonance in human–robot interactions.

“…In other words, contingencies at the interaction level, like those related to its affective context, may promote variability in this labile response. For instance, paying attention to an audiovisual stimulus (e.g., listening to the same story: Pérez et al, 2021 ) leads to spontaneous synchronization ( Figure 3 : spontaneous coordination) between participants, but the extent of this coordination depends on the emotional content of such stimulus and the existent social relationships between the individuals ( Bizzego et al, 2020 ). Another example of how these interactions promote non-intuitive or easily predictable outcomes is the study of Gleibs et al (2016) .…”

The literature on social interactions has shown that participants coordinate not only at the behavioral but also at the physiological and neural levels, and that this coordination gives a temporal structure to the individual and social dynamics. However, it has not been fully explored whether such temporal patterns emerge during interpersonal coordination beyond dyads, whether this phenomenon arises from complex cognitive mechanisms or from relatively simple rules of behavior, or which are the sociocultural processes that underlie this phenomenon. We review the evidence for the existence of group-level rhythmic patterns that result from social interactions and argue that the complexity of group dynamics can lead to temporal regularities that cannot be predicted from the individual periodicities: an emergent collective rhythm. Moreover, we use this interpretation of the literature to discuss how taking into account the sociocultural niche in which individuals develop can help explain the seemingly divergent results that have been reported on the social influences and consequences of interpersonal coordination. We make recommendations on further research to test these arguments and their relationship to the feeling of belonging and assimilation experienced during group dynamics.
