Use of a differential observing response to expand restricted stimulus control.
Journal of Applied Behavior Analysis,

This study extends previous work on the use of differential observing responses
(DOR) to remediate atypically restricted stimulus control. A participant with autism
had high matching-to-sample accuracy scores with printed words that had no letters
in common (e.g., cat, lid, bug) but poor accuracy with words that had two letters
in common (e.g., cat, can, car). In the DOR intervention, she matched the
distinguishing letters of the overlapping words (e.g., t, n, r) immediately
prior to matching the whole words. Accuracy scores improved, and accuracy
remained high when DOR requirements were withdrawn.
