Materials and methods
The commercial versions of the tests were adapted in Greek language by a linguist, three speech language therapists and 2 native speakers of Greek language, having proficiency in English, and two native speakers of English having proficiency in Greek, and changes were contacted, for the best representation of the Greek version. In this research took part 400 participants (m: 200, f: 200) recruited from Greek High Schools. The sample was independent from origin and socio - economic situations. Children with medical problems (ENT, neurological or psychiatric) excluded, because it will influence the test results.

The participants demonstrated clear patterns of responses and there were no differences between expressive and receptive language.
