Signals that are perceived over long distances or leave extended spatial traces are subject to eavesdropping. Eavesdropping has therefore acted as a selective pressure in the evolution of diverse animal communication systems, perhaps even in the evolution of functionally referential communication. Early work suggested that some species of stingless bees (Hymenoptera, Apidae, Meliponini) may use...

In this paper, we focus on the problem of the resolution of multimodal referential expressions in a cooperative man-machine communication setting. We do not only concentrate on how to resolve references involving multiple modalities, but we also indicate how the system can respond cooperatively in case this resolution should fail.

Two groups of children, a pragmatically impaired (PI) group and a group of language-normal (LN) age-matched peers, were compared by use of a referential communication task. Experimenter and child both played the roles of listener and instructor during the task and, in addition, the experimenter sometimes failed to give adequate information when in the role of instructor. Lexical content and str...

Pointing is seen as the cornerstone of human communication, and many researches have provided evidences for fact 
 that infant start to point before they can speak. However, these studies often focused on motivation function behind their pointing behaviors. This study investigated children gesture development by administering a referential communication task. Our findings showed from five ...

In this paper we test the dominant paradigm for modeling the semantics of determined noun phrases called Generalized Quantifier Theory in embodied interactions with robots. We contrast the traditional approach with a new approach, called Clustering Determination, which is heavily inspired by research on grounding of sensorimotor categories, and we show that our approach performs better in noisy...

Gestures are an important aspect of non-verbal communication, but people with schizophrenia have poor comprehension of them. However, the tests of gesture comprehension that have been used present only scenes in which interpersonal meaning is communicated, though there is evidence that people with psychotic disorders tend to perceive communications where none were intended. Such mistakes about ...
