Our goal is to develop a Believable Embodied Agent able to dialog with a user, but we aim at making an Agent that can also combine facial expressions in a complex and subtle way, just like a Human Agent does. We first review a taxonomy of communicative functions that our Agent is able to express non-verbally; but we point out that, due to the complexity of communication, in some cases different...

A language grounding problem is considered for nonuniform sets of modal conjunctions consisting of conjunctions extended with more than one modal operator of knowledge, belief or possibility. The grounding is considered in the context of semiotic triangles built from language symbols, communicative cognitive agents and external objects. The communicative cognitive agents are assumed to be able ...

PURPOSE Huntington's Disease (HD) is a fatal, hereditary neurodegenerative disorder that is characterized by a triad of motor, cognitive and psychiatric symptoms that impact on both communicative effectiveness and the treatment techniques used to maximize communicative participation. The purpose of this article is to describe the application of the World Health Organization's International Clas...

The aim of this paper is to present a specification of speaker's communicative acts of utterances to be carried out gradually by using contextual and cotexual informations. Communicative act is defined as a communicative goal or aim which can be expressed in language L by a distinctive set of conventional cue patterns in specified discourse contexts. In our case, the communicative acts are clas...

When established communication systems cannot be used, people rapidly create novel systems to modify the mental state of another agent according to their intentions. However, there are dramatic inter-individual differences in the implementation of this human competence for communicative innovation. Here we characterize psychological sources of inter-individual variability in the ability to buil...

METHOD the communicative functions expressed by six therapists in interaction with six patients each were analyzed, constituting 36 profiles of communicative functions expressed by the dyad therapist-patien...

Human communicative competence is based on the ability to process a specific class of mental states, namely, communicative intention. The present fMRI study aims to analyze whether intention processing in communication is affected by the expressive means through which a communicative intention is conveyed, that is, the linguistic or extralinguistic gestural means. Combined factorial and conjunc...

Humans are biased toward social interaction. Behaviorally, this bias is evident in the rapid effects that self-relevant communicative signals have on attention and perceptual systems. The processing of communicative cues recruits a wide network of brain regions, including mentalizing systems. Relatively less work, however, has examined the timing of the processing of self-relevant communicative...
