The experiment described in this report investigates second language development and the possibility of determining various levels of language acquisition. The subjects involved are Japanese students learning English. The students are given the task of recalling English kernel sentences after hearing them once. The resulting sentences--the paraphrases and transformation used--reveal data concerning language development. The results, subjected to statistical analysis, illustrate error trends and tendencies toward syntactic confusion, i.e. the Japanese students are able to follow the transformational routine to some extent. If it is possible to map what one can do in English as a foreign language on the individualistic chronological scale of learning history, it might be possible to use a developmental procedure in foreign language acquisition. A list of references is included. (Author/VM)
