La valutazione dello sviluppo metalinguistico tra 9 e 14 anni. Composizione e caratteristiche metrologiche del Tam-2.

This article presentes the structure and the psychometric characteristics of an Italian test devised for assessing metalinguistic development in the age range between late childhood and early adolescence (9-14 y.). The origins of the test is to be found in D. Hakes' work (1980) but with the introduction of a systematic distinction between two types of questions/responses, the first eliciting intuitive linguistic awareness and the subsequent eliciting explicit awareness. The test is composed of 6 subtests, partly metasemantic, partly metagrammatical, and metapho (Comprehension, Synonymy, Acceptability, Ambiguity, Phonological Segmentation). The psychometric characteristics are all very satisfactory.
