Virginia Volterra and Carol Erting have made an important contribu- tion
to knowledge with this selection of studies on language acquisi- tion.
Collections of studies clustered more or less closely around a topic are
plentiful, but this one is 1 nique. Volterra and Erting had a clear plan
in mind when making their selection. Taken together, the studies make
the case that language is inseparable from human inter- action and
communication and, especially in infancy, as much a matter of gestural
as of vocal behavior. The editors have arranged the papers in five
coherent sections and written an introduction to each section in
addition to the expected general introduction and conclu- sion. No
introductory course in child and language development will be complete
without this book. Presenting successively studies of hearing children
acquiring speech languages, of deaf children acquiring sign languages,
of hear- ing children of deaf parents, of deaf children of hearing
parents, and of hearing children compared with deaf children, Volterra
and Erting give one a wider than usual view oflanguage acquisition. It
is a view that would have been impossible not many years ago - when the
primary languages of deaf adults had received neither recognition nor
respect.
