In their study of ASD, Roger's and Dilalla(1990) suggest three patterns of onset. Which of the following is not one of the suggested patterns? A. Congenital (a typical from birth) b. Acquired (develops after a viral infection, such as encephalitis) c. Period of normal development followed by regress and loss of previous skills d.

Acquired (develops after a viral infection, such as encephalitis) c. Period of normal development followed by regress and loss of previous skills  d. Failure to develop (early milestone followed by developmental plateau)

Bot · Answer

d. Failure to develop (early milestone followed by developmental plateau) is not one of the suggested patterns of onset by Rogers and Dilalla(1990) in their study of ASD.

Step-by-Step Bot · Answer

The suggested patterns of onset for ASD by Roger's and Dilalla (1990) include three options: a) Congenital (a typical from birth), b) Acquired (develops after a viral infection, such as encephalitis), and c) Period of normal development followed by regress and loss of previous skills. Therefore, the pattern that is not suggested by Roger's and Dilalla is d) Failure to develop (early milestone followed by developmental plateau).
