When testing is introduced into the diagnostic evaluation, you may be concerned that the results are distorted because of the one-to-one interaction. Typically, children do better in a one-to-one situation when compared to the classroom or during homework. This is actually an asset to the diagnostic evaluation. The benefit provided by one-to-one testing is the psychologist’s ability to measure the child’s
true abilities. Without the distractions of the classroom, and with the added novelty of meeting with the psychologist, children generally enjoy the testing and try hard to please the evaluator. This allows the psychologist to measure what the child truly knows, even if his knowledge is not reflected in his work or on his report cards.
The second benefit of one-to-one testing is that because it takes four to eight hours to complete, the psychologist is usually able to observe the child in several different sessions. Once the novelty wears off and the desire to please becomes hard to sustain, the child eventually displays his typical behavior. Even under the ideal situation of a quiet office and one-to-one attention, children with Asperger’s Disorder can’t help but display their symptoms.
