How does a Verbal Behavior model differ from a Lovaas or discrete trial model?

The VB model, on the other hand, looks first at what the child wants and then teaches the child how to request (in VB terms, how to mand). Initially that may involve only the child reaching for the item to indicate interest.

Another key difference is that VB is much more child-led. Also, early skills, such as manding, are usually taught away from a table and in the natural environment as much as possible. Both Lovaas programs and VB programs are based on the principles of ABA and even though there are many
