The Effects of Specific Learning Difficulties on Processes of Multilingual Language Development

This article reviews current research findings on how specific learning difficulties (SLDs) impact on the processes of multilingual language development. The review includes studies of young language learners in instructed classroom settings, as well as of multilingual children in second language (L2) contexts. Starting with a definition of the concepts of disability and SLDs, it next discusses the interaction of cognitive factors with first language (L1) and L2 literacy development and L2 learning. Also outlined are possible ways in which SLDs can be identified in different L2 learning contexts. A detailed analysis of how cognitive factors influence the development of L2 skills of young learners with learning difficulties is given in the last part of the article.
