This paper describes a computational model of language acquisition based on meaningful interaction between an infant and its caregivers. Learning takes place in an interactive loop between (virtual) caregiver and (virtual) learner who only uses general and cognitively plausible learning strategies and who does not rely on unrealistic prior knowledge about linguistic categories. In this work, the model is used to study the effects of different attentional factors in learning of word-object paring during learner-caregiver interaction.
