REMINDER: The CEU Department of Cognitive Science cordially invites you to a talk (as part of its Departmental Colloquium series) by Giovanni Pezzulo Date: Wednesday, Jan 30, 2013 - 17:00 - 18:30 Location: Department of Cognitive Science, CEU, Frankel Leó út 30-34., Room G15 Sensorimotor communication: a theory of signaling in online social interactionsGiovanni Pezzulo, Institute of Cognitive Sciences and Technologies, Rome Abstract: The study of human communication has principally focused on language use, gesture, and deictics. In online social interactions these forms of communication are complemented by another kind of (sensorimotor) communication: signaling. For example, while we are together a table together, I can push it in a certain direction to signal you where I want it to be placed. Other examples of signaling are over-articulating words in noisy environments and over-emphasizing vowels in child-directed speech. In all these examples, humans intentionally modify their action kinematics to make their goals easier to recognize. We present a formal theory that describes signaling as a combination of a pragmatic and a communicative action (say, push table to move it and push table to inform you), and explains how it simplifies coordination in online social interactions. According to the theory, signaling requires solving a trade-off between the costs of modifying one's behavior and the benets in terms of interaction success. Signaling is thus an intentional strategy; it acts in concert with automatic mechanisms of resonance, prediction, and imitation, especially when the context makes actions and intentions ambiguous and difficult to read. The study of signaling provides an excellent opportunity to understand the adaptive (and evolutionary) value of communication in terms of coordination and interaction success. We're looking forward to see you there (Frankel Leo u. 30-34) !
