Abstract
In the present paper, we examined the error tendency among Japanese Sign Language (JSL) learners when they produced sentences including agreeing verbs. In this study, short sentences written in Japanese were presented to the subjects, and they were asked to grasp the meaning of the sentences. A few minutes later, they were further asked to express the contents in JSL. Their signed expressions were recorded on the video tape. These were analyzed from the viewpoint of “doer's position” and “direction of the verb.” Adult deaf signers participated in the analysis. The result showed the following four characteristics in errors: (1) error in doer's position, (2) change of the starting point, (3) undifferentiated directions, and (4) inadequate planning of contexts in sign production. Moreover, the result also suggested the following five points: (1) setting of doer's position, (2) change of the starting point of the verb, (3) differentiation of the direction of the verb, (4) classification of verb types, and (5) planning of contexts in sign production.
