During social interaction, both participants are continuously active, each modifying their own actions in response to the continuously changing actions of the partner. This continuous mutual adaptation results in interactional synchrony to which both members contribute. Freely exchanging the role of imitator and model is a well-framed example of(More)
The Robota project constructs a series of multiple-degrees-of-freedom, doll-shaped humanoid robots, whose physical features resemble those of a human baby. The Robota robots have been applied as assistive technologies in behavioral studies with low-functioning children with autism. These studies investigate the potential of using an imitator robot to assess(More)
Twenty children with autism (mean age, 5 years) were recruited for the study from a school for children with autism. The children were randomly assigned to an imitation (n = 10) or contingently responsive (n = 10) interaction group based on a stratification table for gender and developmental and chronological age. The sessions consisted of four phases, with(More)
Recent development in diffusion spectrum brain imaging combined to functional simulation has the potential to further our understanding of how structure and dynamics are intertwined in the human brain. At the intra-individual scale, neurocomputational models have already started to uncover how the human connectome constrains the coordination of brain(More)
Brain correlates of the sense of agency have recently received increased attention. However, the explorations remain largely restricted to the study of brains in isolation. The prototypical paradigm used so far consists of manipulating visual perception of own action while asking the subject to draw a distinction between self- versus externally caused(More)
OBJECTIVE A core component of social functioning is the capacity to attribute mental states to others and to understand intention as psychologic cause. The hypothesis of this study was that dementia of the Alzheimer type (DAT) patients show an impaired understanding of psychologic cause although they remain able to understand physical causality. METHODS(More)
Social interaction is a coregulated coupling activity that involves at least 2 autonomous agents. Numerous methodological and technical challenges impede the production of natural social interaction within an Magnetic Resonance Imaging environment under controlled conditions. To overcome the obstacle, we chose a simple format of social interaction, namely(More)
Several experimental studies have shown the usefulness of computers for autism, but software design remains poorly documented. Our multidisciplinary research focuses on educational HCI for autism. We compared two domains of learning: social dialogue understanding and spatial planning, our hypothesis being that people with autism will be less skilful in the(More)
The computation by which our brain elaborates fast responses to emotional expressions is currently an active field of brain studies. Previous studies have focused on stimuli taken from everyday life. Here, we investigated event-related potentials in response to happy vs neutral stimuli of human and non-humanoid robots. At the behavioural level, emotion(More)
