Abstract(in English) This study shows a possible cause of the occurrence of the stepwise shape of word learning curves reported by Minami et al. (2012). In our simulation, co-occurrence frequency of each word and its possible referents are counted, and a word is judged as acquired when the statistical significance of the co-occurrence of the word and its referent exceeds a threshold. We show that the stepwise shape of word learning curves occurs in our simulation, and examine the cause of the shape. We believe that the stepwise shape is generally observed in competitive learning systems such as winner-take-all neural networks.
