Tactย Extensionย refers to the process by whichย stimulusย andย responseย classes are established, allowingย generalizationย of tacts. This means that novel stimuli, which share certain characteristics with known stimuli, can evoke the sameย tactย behaviorย without direct training, enabling the speaker to label new items based on previously learned concepts.
Example
A child learns toย tactย a โdogโ when they see their pet at home. Later, when they see a wolf at the zoo, they call it a โdog.โ This demonstrates aย tactย extension, as the child is generalizing theย tactย behaviorย to a novelย stimulusย (wolf) that shares similarities with the knownย stimulusย (dog).
