Abstract(in English) This study investigates cross-linguistic universality of word leaning using English and Spanish Lex2005 CDI database along with our Japanese CDI database (from 1,699 toddlers). We defined the word-comprehension and -production days as the days when 50% of the children comprehend and produce a word, respectively. We also calculated the period between comprehension and production. Between two languages, the correlations of comprehension days and periods between comprehension and production were calculated category on category and word on word. For category-on-category comparison of the comprehension days, English-Japanese and Japanese-Spanish correlation coefficients were 0.79 and 0.76, respectively. For category-on-category comparison of the comprehension days, English-Japanese and Japanese-Spanish correlation coefficients were 0.75 and 0.74, respectively. For word-on-word comparison of the periods between production and comprehension, English-Japanese, and Japanese-Spanish correlation coefficients were 0.57 and 0.62, respectively. For word-on-word comparison of the periods between production and comprehension, English-Japanese and Japanese-Spanish correlation coefficients were 0.72 and 0.72. These results confirmed there are strong correlations in word-comprehension days and periods between comprehension and production as seen through both category-on-category and word-on-word comparisons. This suggests that there is cross-linguistic universality of word acquisition ages in comprehension and production.
