This study aims to clarify the relationship between subjective perception and performance in the communicative learning using Synchronous Computer-Mediated Communication (SCMC). In this study, we developed four types of SCMC: videoconferencing (image and voice), audioconferencing (no image and voice), text-chat with image (image and no voice) and plain text-chat (no image and no voice). In this experiment, each system aids learners in being aware of and uttering a target formulaic expression as learning objectives. We investigated the effect of each system on psychological perception and productive performance, as well as the relationship between perception and performance. The results show that image and voice promote consciousness of natural communication and relief, while a text-mediated system enhances confidence in grammatical accuracy. In order to clarify the relationship between perception and performance, multiple regression analysis was conducted using perception as the independent variable and performance as the dependent variable. The results indicate that consciousness of natural communication and the use of the voice communication affect factors such as the number of utterances, while interlocutor's image and voice and consciousness of grammatical accuracy lead to self-correction.
