Abstract Most experimental protocols examining joint attention with the gaze cueing paradigm are “observational” and “offline”, thereby not involving social interaction. We examined whether within a naturalistic online interaction, real-time eye contact influences effect (GCE). embedded in an interactive protocol iCub humanoid robot. This has advantage of ecological validity combined excellent control. Critically, before averting gaze, either established or not, manipulation enabled by...

Sense of joint agency (SoJA) is the sense control experienced by humans when acting with others to bring about changes in shared environment. SoJA proposed arise from sensorimotor predictive processes underlying action and monitoring. Because a ubiquitous phenomenon occurring we perform actions other humans, it great interest importance understand whether—and under what conditions—SoJA occurs collaborative tasks humanoid robots. In this study, using behavioral measures neural responses...

Task-irrelevant robot gaze evokes neural suppression, delays decisions, and alters social decision-making strategies.

Eye contact established by a human partner has been shown to affect various cognitive processes of the receiver. However, little is known about humans' responses eye humanoid robot. Here, we aimed at examining oscillatory brain response with (or lack thereof) was embedded in gaze-cueing task and preceded phase gaze-related attentional orienting. In addition effect on recipient, also tested its impact effects (GCEs). Results showed that participants rated as more engaging responded higher...

The present study aims at investigating how eye contact established by a humanoid robot affects engagement in human-robot interaction (HRI). To this end, we combined explicit subjective evaluations with implicit measures, i.e. reaction times and tracking. More specifically, employed gaze cueing paradigm HRI protocol involving the iCub robot. Critically, before moving its gaze, either or not user. We investigated patterns of fixations participants' on robot's face, joint attention ratings as...

Abstract The concept of scaffolding refers to the support that environment provides in acquisition and consolidation new abilities. Technological advancements allow for cognitive capabilities, such as second language using simple smartphone applications There is, however, one domain cognition has been scarcely addressed context technologically assisted scaffolding: social cognition. We explored possibility supporting competencies a group children with autism spectrum disorder engaged...

Joint attention is a pivotal mechanism of human social cognition. Traditionally, joint has been experimentally investigated by means the gaze cueing task in screen-based settings. Recently, implemented more naturalistic and interactive settings with embodied iCub robot, allowing for investigation concurrent factors influencing attention. Previous studies found that communicative before cue (i.e., mutual or avoiding participants) influenced subsequent eliciting gaze-cueing effect only...

Eye contact constitutes a strong communicative signal in human interactions and has been shown to modulate various cognitive processes states. However, little is known about its impact on gaze-mediated attentional orienting the context of interplay with strategic top-down control. Here, we aimed at investigating how social component eye interacts To this end, designed gaze cuing paradigm iCub humanoid robot, which either established participants before averting or avoided their eyes. Across...

The present study highlights the benefits of using well-controlled experimental designs, grounded in psychology research and objective neuroscientific methods, for generating progress human-robot interaction (HRI) research. More specifically, we aimed at implementing a well-studied paradigm attentional cueing through gaze (the so-called "joint attention" or "gaze cueing") an HRI protocol involving iCub robot. Similarly to documented results gaze-cueing research, found faster response times...

Abstract In the last decade, scientists investigating human social cognition have started bringing traditional laboratory paradigms more “into wild” to examine how socio-cognitive mechanisms of brain work in real-life settings. As this implies transferring 2D observational 3D interactive environments, there is a risk compromising experimental control. context, we propose methodological approach which uses humanoid robots as proxies interaction partners and embeds them protocols that adapt...

The present study highlights the benefits of using well-controlled experimental designs, grounded in psychology research and objective neuroscientific methods, for generating progress human-robot interaction (HRI) research. In this study, we implemented a well-studied paradigm attentional cueing through gaze (the so-called “joint attention” or “gaze cueing”) an HRI protocol involving iCub robot. We replicated standard phenomenon joint attention both terms behavioral measures event-related...

Abstract Joint attention is a pivotal mechanism underlying human ability to interact with one another. The fundamental nature of joint in the context social cognition has led researchers develop tasks that address this and operationalize it laboratory setting, form gaze cueing paradigm. In present study, we addressed question whether engaging robot face culture-specific. We adapted classical gaze-cueing paradigm such avatar cued participants’ subsequent either participants eye contact or...

We examined whether within a naturalistic online interaction, real-time eye contact influences effect (GCE). embedded in an interactive protocol iCub humanoid robot. This has advantage of ecological validity combined excellent control. Critically, before averting gaze, either established or not, manipulation enabled by algorithm...

Mild traumatic brain injuries (mTBI) generate acute disruptions of function and a subset patients shows persisting cognitive, affective, somatic symptoms. Deficits in the executive domain are among more frequent cognitive impairments reported by mTBI patients. By means independent component analysis, event-related potential components from visual cued go/nogo task, namely contingent negative variation (CNV) NoGo-P3, were decomposed into distinct that have been shown to be associated with...

Sense of Agency (SoA) is the feeling control over one's actions and their outcomes. A well-established implicit measure SoA temporal interval estimation paradigm, in which participants estimate time between a voluntary action its sensory consequence. In present study, we aimed to investigate whether valence outcome modulated SoA. The was manipulated through interaction partner's (i) positive/negative facial expression, or (ii) type gaze (gaze contact averted gaze). partner humanoid robot...

This paper reviews methods to investigate joint attention, and highlights the benefits of new methodological approaches that make use most recent technological developments such as humanoid robots for studying social cognition. After reviewing classical addressing attention mechanisms with controlled screen-based stimuli, we describe accounts propose need more natural interactive experimental protocols. Although allow ecological validity, they often face challenges control in interaction In...

Communicative gaze (e.g., mutual or averted) has been shown to affect attentional orienting. However, no study date clearly separated the neural basis of pure social component that modulates orienting in response communicative from other processes might be a combination and effects. We used Transcranial Magnetic Stimulation (TMS) isolate purely effects on Participants completed gaze-cueing task with humanoid robot who engaged either averted prior shifting its gaze. Before task, participants...

Eye contact constitutes a strong social signal in humans and affects various attentional processes. However, eye with another human might evoke different responses compared direct gaze depicted on screen. Previous embodied gaze-cueing experiments iCub humanoid robot showed modulations effect using long stimulus-onset-asynchrony (SOA: 1000 ms, no predictive cue). Instead, did not modulate the shorter SOA (500 In present study, we investigated whether robot’s screen could by adapting previous...
