ABSTRACT
At the end of training, the feathered sharpshooter never fired the gun when Breland was in its sight and always fired it when he wasn't. As a result of the discrimination-training procedure, the mere presentation of the card caused Bobby to make the correct response. For example, in the simple stimulus-discrimination procedure, the people deal only with the response class functionally defined in terms of the pressing of the lever. The Differential-Reinforcement Procedure vs. the Stimulus-Discrimination Procedure Of course, the same differences apply to differential punishment procedures and stimulus-discrimination procedures using punishment contingencies. Furthermore, behavior analysts often start with mand training, because it lends itself so readily to incidental teaching and can help to reduce problem behaviors. Although the contingency wasn’t always operating, there was no functional SD associated with the occasions when the experimenters were present, because both Velma and Gerri were deaf and blind.
