21.4 ASL Intraverbal

A sign in ASL as the result of the word written in English is not analogous to textual behavior because there is no point-to-point correspondence between the sign and the controlling stimulus. This would have to be classified as a type of ASL intraverbal. Another form of ASL intraverbal would involve making the sign “cat” as a result of seeing the sign “dog.” The ASL intraverbal which had the English word as the controlling variable is the same type of intraverbal discussed in the acquisition of a foreign language. Indeed, ASL and English are two different languages.
