escape from demands hypothesis, they had an adult make a normal demand towards the child, but terminate it if the self injurious behavior occurs. For the sensory stimulation hypothesis, the child is left alone without the presence of anyone or any stimulating activities. Iwata compared the levels of self injurious behaviors across the three conditions and demonstrated that the function of the problem behavior for each child was different. Some wanted attention, others escaped while some were maintained by automatic reinforcement. As shown here, it is very important to conduct a functional assessment to determine what exactly is maintaining the behavior before any function interventions are taken.
212:. The main advantage of direct observation is that the antecedents and consequences are recorded as it happens instead of recollection of memory. Therefore, the information recorded is generally more accurate. The main disadvantage of direct observation is it requires a considerable amount of time and effort to implement. Another thing about direct observation is, like indirect methods, it can only demonstrate a correlation but not a functional relationship.

true, then the problem behavior should occur much more often in the first condition than the second. Results show that their hypothesis was indeed true as the aggressive behavior occurred at a much higher frequency in the first condition. The researchers concluded that the boy's problem behavior was indeed maintained by the antecedent of academic demands and the consequence of escape from the demands.

Experimental methods involve manipulating either the antecedent or consequent variables to determine their influence on the problem behavior. This is the only method that can demonstrate a functional relationship between the antecedent stimulus or the reinforcing consequence and the problem behavior.

A functional assessment should always be conducted before treating a problem behavior. To develop appropriate treatment, one must have the correct information about the antecedents and consequences controlling the behavior because treatment involves manipulating these environmental events to evoke a
