Evaluation of multiple-alternative prompts during tact training.

This study compared 2 methods of fading prompts while teaching tacts to 3 individuals who had been diagnosed with autism spectrum disorder ( ASD). The 1st method involved use of an echoic prompt and prompt fading. The 2nd method involved providing multiple-alternative answers and fading by increasing the difficulty of the discrimination. An adapted alternating-treatments design showed that both procedures were more effective than a no-intervention control condition. Providing multiple alternatives did not increase error rates or teaching time, and better maintenance was shown for tacts taught with the multiple-alternative prompt. [ABSTRACT FROM AUTHOR]
