Basic Psychological Needs Theory (BPNT) is one of several mini theories within Self-Determination Theory, a framework developed by Deci and Ryan’s (1985) to study human motivation. As part of a larger, on-going project, the three main components of BPNT, autonomy, relatedness and competence, are used as points of evaluation to determine the autonomy-supportiveness of a Japanese self-access learning center (SALC). Based on the analysis of 107 interviews, we will highlight how the SALC is structured to be an autonomy-supportive environment. Additionally, we will provide insight into the importance of relatedness to the learners of our SALC and explore the contractions between their desire to communicate in English and their reluctance to actualize their desires. Based on these findings, future interventions will be discussed to outline actions the SALC can take in order to further develop the autonomy-supportive nature of the self-access environment.
