Research note an investigation of the cognitive development of italian-english bilinguals and italian monolinguals from rome

The cognitive development of Italian-English bilinguals and Italian monolinguals was studied on measures of metalinguistic awareness, creativity, nonverbal abilities, and reading achievement. On the whole, results were found to be consistent with Cummins’ Threshold Hypothesis, in that an overall superiority was found only for those children who had attained a high degree of bilingualism. © 1993 Taylor & Francis Group, LLC.
