volumen léxico

Obviously I can see the link but am just not sure if "lexical volume" is the usual term for my context. I'm not sure what your "go figure" comment is supposed to mean ....... seems a little unnecessary. BTW "produce" is the expression used in the articles on chidlren's L1 language cited in my source text so would not seem to have fallen out of favour.

And the same is true also for vocabulary size .... but I think I will have to use it since Rescorla et al. seem to be fairly big shots in the child language acquisition world!

But you wouldn't say a child has a "lexicon size of 16 words". You'd say the child has a lexicon of 16 words. I don't see the point in using two words where one suffices.

for your help. I have located an article cited in my text which includes various examples of "vocabulary size" and one of "lexicon size" and here they are used as synonyms: Intake expressive vocabulary size as reported by their mothers on the language development survey (LDS) was 16 words, about one-tenth of the lexicon size of normally developing toddlers.
So I seem to have answered my own question ...
