The difference as I understood it to be is that functional analysis looks at specific behaviors (pica perhaps) in terms of arriving at an approach. That is behavior is analyzed in terms of consequences or antecedents and a suitable strategy is derived as a result. Applied behavior analysis is a strategy whereby individuals with autism are programmed in terms of cognitive development in a very systematic and intensive way. My understanding is that this approach has been somewhat successful in overcoming many of the deficits associated with autism. It does require a major commitment in terms of one:one involvement for significant periods of time. The individual with autism (and exhibiting pica) is four years of age and attends school and structured day-care. He is receiving involvement in terms of communication (is basically non-verbal) and self-care (toilet-training, etc.). Does this scenario indicate that applied behavior analysis would be a priority? As always I do appreciate any suggestions that would be of benefit. O.T. would be nice and is expected in the near future (sensory integration is expected to be the primary focus).
