Interaction between working memory and long-term memory: A study in children with and without language impairment.

Individual differences in working memory have been related to interactions between working memory and long-term memory (LTM). The present study examined this interaction in children with and without language impairment. We used two listening span tasks and two nonword repetition tasks. The results suggest a strong interaction among age, language status, and task complexity. Children with specific language impairment showed consistently poor performance across tasks and indicated a weakness in using long-term knowledge to support working memory performance. The findings show that these children do not benefit from various manipulations designed to enhance working memory performance via LTM support due to a combination of inefficiencies in maintaining and updating items in working memory and retrieving information from LTM, in part because of their poor resistance to interference.
