 The results imply that in routine family conversations, parents supply children with considerable information on the way language is used to communicate information.Gleason has carried out significant research involving the learning and maintenance of second languages by sequential bilinguals.She has studied the acquisition of a second language while retaining the first (additive bilingualism),
examining discourse behaviors of parents who follow the one person-one language principle by using different languages with their child
She has also studied language attrition, the loss of a known language through lack of use,
and suggests that the order in which a language is learned is less important in predicting its retention than the thoroughness with which it is learned.
