query about the pace of early child language development

[Nan Ratner]

A colleague of mine has asked a question that perhaps you can help me with. He wonders if the rate of language development (e.g., ages at which major milestones are achieved, or ages associated with values for measures such as MLU) has "sped up" over the years? Aside from trying to compare current studies that report a value for something like MLU with early work by Brown and colleagues, for example, has this question been addressed in any formal way?

best regards to all on the list,

Nan
