In the present study we assessed the forms and functions of prelinguistic communicative behaviors for 120 children and adults with Rett syndrome using the Inventory of Potential Communicative Acts (IPCA) (Sigafoos et al. Communication Disorders Quarterly 21:77-86, 2000a). Informants completed the IPCA and the results were analysed to provide a systematic inventory and objective description of t...

In the philosophical theory of communicative action, rationality refers to interpersonal communication rather than to a knowing subject. Thus, a social view of rationality is suggested. The theory differentiates between two kinds of rationality, the emancipative communicative and the strategic or instrumental reasoning. Using experimental designs in an fMRI setting, recent studies explored simi...

BACKGROUND Constructivist approaches to learning focus on learning environments in which students have the opportunity to construct knowledge themselves, and negotiate this knowledge with others. Discovery learning and collaborative learning are examples of learning contexts that cater for knowledge construction processes. We introduce a computer-based learning environment in which the two form...

This article is a comparison of the Natural Approach and Communicative Language Teaching. Using the Richards and Rodgers’ model for conceptualizing approaches and methods described in Approaches and Methods in Language Teaching, 1986, Cambridge University Press, I compare and contrast these two approaches carefully at the level of approach, design and procedure. At the level of approach, I look...

Malgré la présence du numérique à fois comme nouveau terrain d’étude et nouvel outillage d’analyse, possibilité d’adopter une approche fondamentalement computationnelle de l’étude des récits semble très peu explorée, alors même que les modèles computationnels récit existent, notamment en informatique. Après un survol ces modèles, nous esquissons perspective démarche scientifique modélisation/si...

This study explores the potential of utilising certain prosodic qualities of function-specific vocal expressions in order to design effective non-speech user interface sounds. In an empirical setting, utterances with four context-situated communicative functions were produced by 20 participants. Time series of fundamental frequency (F0) and intensity were extracted from the utterances and analy...
