This study investigated how a learner’s native language phoneme inventory affects the perception and production of second language speech sounds. We sought to determine whether the addition of novel phonemes through L2 acquisition causes a restructuring of the perceptual map, thereby altering the perceptual space and the mapping of acoustic features to segmental categories, including native language phonemes. Perceptual experiments with L1 Chinese- and L1 Japanese-speakers showed that native language inventories dictate L2 perceptual confusion and further suggested that learning an L2 leads to restructuring of the perceptual map. In addition, spectrographic analysis of acoustic features in the production of L2 sounds that are similar to L1 segments showed that the precise acoustic features change depending on a learner’s stage of acquisition.

本研究では、一つの視点（機能範疇Ｔ）から、第二言語学習者の心的文法を記述することによって、形態と統語、素性と語彙と形態統語操作、インターフェースと心的処理の関係を明らかにし、モデル化による包括的説明を提案する。特に分散形態論の枠組みで、心的辞書構築、語彙項目・素性配分、形態統語操作、言語モジュール外の心的処理を記述するモデルを提案する。英語の機能範疇Ｔとその素性の習得には、複数の形態統語現象が関わっており、第二言語学習者は、これらの規則違反に対する敏感度、違反文容認度、文産出の点で、母語話者とは異なる可能性がある。コーパス並びに心理言語学実験による実証的データに基づき、理論的研究を通して、素性再配置、列挙、インターフェース、解釈不可能性などの仮説の妥当性を検証し、母語、インプットの影響、学習可能性について、知識・処理・記憶に基づく原理的説明を試みる。2019年度は、２０１８年度から進めてきた文献研究に加えて、i）時制節における明示的主語の義務的使用、ii）助動詞・動詞屈折による時制の表示、iii）助動詞・動詞屈折による主語の人称・数の表示、iv)否定節および疑問節における助動詞の使用、v）動詞、目的語、否定辞・頻度副詞の位置関係の「規則」に関して、心理言語学実験によるデータの収集・分析を開始した。英国ヨーク大学およびシェフィールド大学で、英語母語話者からのデータ収集を行なった。また、台湾の国立高雄師範大学および日本の大学で、英語学習者からのデータ収集を行なった。データ収集では、Superlabを用い自己ペース読解速度測定を行った。同時に、英語学習者に対しては熟達度測定のためにOxford Quick Placement Testを実施している。コーパスデータ分析のために、2月に研修を目的とした合宿を実施した。

We have investigated how L2 learners build new phonological categories by assembling novel weightings of acoustic cues and mapping them onto new segmental representations. The series of experimental studies we have conducted has shown that the use of particular acoustic cues changes over the course of L2 acquisition. We have also shown that resulting refinements in selective attention improve L2 perceptual accuracy, although the precise effect of such selective attention differs across phonological categories.

Focusing on the Japanese, English, Chinese, and Tagalog languages, our research project has explored similarities and differences in linguistic knowledge and language processing among heritage language speakers, native speakers, and second language learners through various empirical methodologies. In particular, we have examined the production and comprehension of relative clauses in Chinese, Japanese and Tagalog, the interpretation of reflexive pronouns in Japanese through a look-while-listening eye tracking experiment (Eye Link 1000, SR Research, Inc.), and the second language acquisition of English articles and multiple adjective ordering, and found evidence of both cross-linguistic effects as well as universal properties.

The purpose of the investigation was to conduct research on the following issues: The influence of a second language on one's first language (L1); the maintenance and/or the loss of proficiency in the L1 and the acquisition, maintenance and possible loss of proficiency in the second language (L2). We have investigated the causes of change (if any change has taken place) and proposed the type of education a child or a language learner needs for further language development. The main findings are the following:
(1) Regarding the L1 loss of foreign children who reside in Japan, some children showed gain while others showed loss in their cognitive ability. Chinese children generally observed development in L2 Japanese but there was a variation among Filipino children. (2) Japanese returnees showed no loss in their listening abilities and grammar in L2 English. (3) Japanese and Spanish learners of English and English and Chinese learners of Japanese observed some L1 effects in their L2.
A Dual-Model in L2 Phonological Acquisition

Our previous research has revealed that L2 learners use acoustic cues that are not phonologically relevant for segmental perception in their L1. As a result, we have proposed a model for phonological perception we term the Category Activation Threshold Model. This model maintains that sensitivity to acoustic details not used for categorical distinction is actively suppressed in the course of mapping acoustic cues to phonological categories.
