According to Stern, a renowned psychologist, the mind process can be described as "the ability to fit in new situations in a convenient, fast, and effective way".This conformity, that is to say, the forms of the adaptive person, gradually changes throughout its development. With the separate tests discussed in the previous chapters, Brunet-Lezine becomes clear with the Terman tests. However, the general line of mind development can be missed when these tests are handled separately. It is important not to forget this general appearance and to leave a broad view of the child when the mind is developing/ismail.
