Acquisition of mands and tacts with concurrent echoic training.
Journal of Applied Behavior Analysis,
Previous studies have identified a number of effective teaching procedures to
increase verbal behavior in individuals with developmental disabilities. However,
few studies have evaluated modifications of treatment procedures when children
fail to acquire communication skills. In the present investigation, a 4-year-old
boy with autism failed to acquire unprompted mands and tacts during mand-only
and tact-only training. Results indicated that combining echoic training with mand
or tact training increased unprompted manding and tacting.
DESCRIPTORS: echoic training, language acquisition, mand, tact, verbal behavior
