LENA

[isa barriere]

It seems that you did not finish writing your message (?).

Anyway I think Kathy's and other's reactions did not have to do with the
actual benefit of this tool for researchers (which as you point out may be
great) it had to do with its use by parents and whether it should be viewed
as a "replacement" for evaluations by SLP, Developemtal Psych.


Yours,

Isabelle Barriere, PhD
