Phonotactics and Well-formedness Condition of the Japanese Sign Language Syllables

本研究的目的是寻找日本手语音节的良整条件，即满足最大音节复杂度约束的音节所受的约束条件，研究结果如下：1. DI型音节可能没有优势手的7手形、8手形或78手形：它们是无名指和/或中指积极参与手形形成的音节，即，无名指和/或中指突出的手形此外，像V、3和4这样的手形，它们有三个或三个以上突出的手指，也被禁止出现在DI音节的优势手上。2.音节的良构性不仅取决于音节的信息量，还与音节子结构的信息量有关，特别是与两个手形的信息量有关。不存在双手信息量占音节总信息量80%以上的Ⅲ型音节。

This rewarch has been done to find the well-irmnedness conditions of the Japanese Sign Language syllables, the conditions being the constraints which apply to the syllables that observe the Maximum Syllable Complexity Constraints.The results of the research are the follows.1. The type-DI syllables may not have the handshapes called the 7 handshape, the 8 handshape, or the 78 handshape on the dominant hand : they are those with the ring finger and/or middle finger positively involved in the handshape formation, i.e., handshapes with the ring fingers and/or middle fingers salient In addition, the handshapes like the V, 3, and 4 handshapes, which have three or more than three salient fingers, are also prohibited from appearing on the dominant hand of the type-DI syllable.2. The well-formedness of the syllable are not only dependent on the amount of information of the syllable but is also related to the amount of information of the syllabic suboonstructions : especially, the amount of information of both handshapes. There is no type-III syllable in which the amount of information of both hands accounts for more than 80% of the total amount of information of the syllable.
