Lederberg/etal:2013
-------------------

How is manual babbling defined and how can it be distinguished from
random movements?

What about languages that have a completely different
(morphosyntactical) structure - Can we still apply the findings of the
paper?

When talking about the bimodal input (SimCom / spoken language), the
paper says that after 30 months of age, the effects of communication
mode disappeared. Does this mean there is an advantage to using SimCom
below 30 months, but after this age, the advantage is lost and the
spoken language only children are able to catch up with their peers?
