This study explores the patterns of gesture and speech combinations from the babbling period to the one-word stage and the temporal alignment between the two modalities. The communicative acts of four Catalan children at 0;11, 1;1, 1;3, 1;5, and 1;7 were gesturally and acoustically analyzed. Results from the analysis of a total of 4,507 communicative acts extracted from approximately 24 h of at...

There is a controversy about the mechanisms involved in the interspecific communicative behaviour in domestic dogs. The main question is whether this behaviour is a result of instrumental learning or higher cognitive skills are required. The present investigations were undertaken to study the effect of learning processes upon the gaze towards the human's face as a communicative response. To suc...

Domestic dogs show remarkable communicative abilities in their interaction with people. These skills maybe explained by the interaction between the domestication process and learning experiences during ontogeny. Studies carried out on other species of canids, which have not been domesticated are relevant to this topic. The purpose of this article is to study the effect of instrumental learning ...

PURPOSE To investigate, in patients with Parkinson's disease (PD), the coping strategies; the most reported vocal symptoms; and the relation between coping, voice symptoms, and communicative aspects. METHODS Seventy-three subjects were included in the sample, 33 of which were participants in the experimental group (EG) with diagnosis of PD and 40 were control subjects, that is, healthy and wi...

adopting a humanistic, communicative-based approach to semiotics, this paper aims at investigating the status of linguistic signs and their interaction with other communicative signs. the status of linguistic sign is first studied in semiotic theories spanning ancient, middle ages and modern era. based on the commonalities envisaged in four contemporary semiotic theories done in the spirit of t...

In this work we present a typology of eye closing behaviours based on a semantic taxonomy of communicative signals. The types of eye closing we investigate are blinks, eye-closures and winks performed during political debates. While other studies in the literature attempt to classify blinks and eye-closures according to their duration or (in)completeness of the closure, our study aims to distin...

We outline some components of a mentalist theory of human communicative competence. Communication in our species is an intentional and overt type of social interaction, based on each agent's capability of entertaining shared mental states and of acting so as to make certain mental states shared with the other. Communicative meaning is a matter of ascription: it is not an intrinsic property of a...

Information graphics, such as bar charts and line graphs, generally have a communicative message that they are intended to convey when they appear in popular media. The communicative signals present or absent in the graphic help convey these underlying intended messages. We have designed a Bayesian system that automatically extracts communicative signals from a grouped bar chart information gra...
