From this perspective, the infant?s first steps in the acquisition of the ambient language are seen as a consequence of the infant?s general capacity to represent sensory input and the infant?s interaction with other actors in its immediate ecological environment. On the basis of available experimental evidence, it will be argued that ETLA offers a productive alternative to traditional descriptive views of the language acquisition process by presenting an operative model of how early linguistic function may emerge through interaction. %K ecological theory of language acquisition, infant word learning, infant directed speech, cross-modal synchrony, gaze tracking %P 55-62 %E Luc Berthouze %E Fr?d?ric Kaplan %E Hideki Kozima %E Hiroyuki Yano %E J?rgen Konczak %E Giorgio Metta %E Jacqueline Nadel %E Giulio Sandini %E Georgi Stojanov %E Christian Balkenius %V 123 %D 2005 %I Lund University Cognitive Studies %L cogprints4965
