The book demonstrates that it is possible to study the language faculty with the core scientific method, i.e., by deducing definite predictions from hypotheses and obtaining and replicating experimental results precisely in accordance with the predictions. In light of the "reproducibility crisis" as extensively addressed in recent years in a number of fields, the demonstration that rigorous replication can be obtained in the study of the language faculty in terms of correlational and categorical predictions is particularly significant. While the claim has been made over the years that Chomsky's research program is meant to be a scientific study of the language faculty, a conceptual and methodological articulation has never been made as to how we can accumulate our knowledge about the language faculty by the basic scientific method, including, most crucially, how exactly we can put our hypotheses to rigorous empirical and experimental test. The book proposes how to do that by providing a conceptual basis for the methodology for language faculty science. The book also offers empirical demonstrations of the viability of the proposed methodology. The experiments were conducted with Japanese and English speakers. Overall, the book explores new directions for the study of the mind.

This book explores how we can aspire to accumulate knowledge about the language faculty in line with Feynman's 'The test of all knowledge is experiment'. The two pillars of the proposed methodology for language faculty science are the internalist approach advocated by Chomsky and what Feynman calls the 'Guess-Compute-Compare' method. Taking the internalist approach, the book is concerned with the I-language of an individual speaker. Adopting the Guess-Compute-Compare method, it aims at deducing definite predictions and comparing them with experimental results. It offers a conceptual articulation of how we deduce definite predictions about the judgments of an individual speaker on the basis of universal and language-particular hypotheses and how we obtain experimental results precisely in accordance with such predictions. In pursuit of rigorous testability and reproducibility, the experimental demonstration in the book is supplemented by an accompanying website which provides the details of all the experiments discussed in the book.

The papers in this volume are from the seventeenth Japanese/Korean Linguistics Conference, which was held at the University of California, Los Angeles in November of 2007. The articles cover a broad range of topics in Japanese and Korean linguistics, including phonology, morphology, syntax, semantics, historical linguistics, discourse analysis, prosody, psycholinguistics, sociolinguistics, acquisition, and grammaticalization.
