Background: Children who are bilingual and have speech sound disorder are likely to be under-referred, possibly due to confusion about typical speech acquisition in bilingual children. Aims: To investigate what is known about the impact of bilingualism on children's acquisition of speech in English to facilitate the identification and treatment of…

The properties of four different tests of the treatment effect in experiments using linguistic materials are examined. (Author/RM)

Answers to theoretical questions about the place of input in a formal second language acquisition model are dependent on a distinction between two kinds of learner hypotheses. Type-N hypotheses require "negative evidence" for testing, while Type-P hypotheses are tested on the basis of "positive data" alone. (Author/CB)

Previous work by the authors permitted them to hypothesize the existence of certain universal cognitive strategies that play a significant role in child second language acquisition. Forming the basis of the "creative construction process" in L2 learning, these strategies have heretofore remained unspecified. This paper offers new…

Three methods for second language data collection are compared: free composition, picture description and translation. The comparison is based on percentage of errors in a grammatical category and in a source category. Most results obtained from the free compositions and picture descriptions tended to be similar. Greater variation was found for…
