Language, Literacy, and Mental States.

There is a parallelism between children's mastery of the language of mind and their thinking about the world. Children work out distinctions appropriate to language at the same time that they are working out concepts for thinking. These assumptions were tested by measuring children's mastery of verbs of saying and meaning. In one study, 72 children from grades 1 through 4 were subjects. Although knowledge of cognitive verbs did not relate directly to reading skill, there was a relationship between reading skill and the tendency to justify answers by appealing to the text. This tendency increased with grade level.
