example, in ABA, teaching symbolic communication
usually involves one or two instructors working with
a child, using spatial fading to prompt correct
responding, and following an instructional sequence
beginning with teaching the child first to exchange a
symbol for a preferred object, then to an approach an
adult before exchanging the symbol, then to discrim-
inate between symbols for preferred and non-pre-
ferred objects, and so on (Bondy & Frost, 2003). In
ABA, teaching sign language involves one instructor
working with a child, using systematic shaping or
prompt/fading procedures to increase the accuracy of
signs, following a progression from basic requests or
objects labels to more advanced communication, and
reinforcing correct responding (Carr, 1981). In eclec-
tic programs, alternate teaching procedures were used
such as providing instruction in a group of children,
following a different sequence of instruction, or using
varied prompting and reinforcement procedures.
