1. 1. The kaleidoscope of communication : Different perspectives on communication involving children with severe multiple disabilities

   Författare :Cecilia Olsson; Siv Fischbein; Mats Granlund; Juliet Goldbart; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dyadic interaction; pre-symbolic communication; multiple disabilities; system theory; communication process; communication models; Education; Pedagogik;

   Sammanfattning : This thesis consists of six publications presenting a theoretical framework, a methodological proposal and three empirical studies. The aim of the work is; to gain knowledge on how children with severe multiple disabilities communicate with their caregivers, to analyse how different research strategies can add knowledge from different perspectives on communication, and to develop models for analysing and describing the dyadic interaction.
