communication method. This finding suggests that
preference may influence how quickly children learn
to communicate. We are undertaking further analyses
to confirm any such relation between preference and
speed of learning.
It is important to note that these key findings are so
far limited to the teaching of communicative requesting,
which is generally considered a more basic communication
skill. A second study to commence later in 2012 will
extend the present comparisons to more socially oriented
communication skills.
In summary, these early data suggest that children with
autism can learn to use a variety of AAC systems and that
they are likely to indicate a preference for one mode of
communication. However, it is not known how stable these
preferences are over time or how these preferences may
support the development of more complex communication.
