The field of self-access language learning (SALL), which is an established way of supporting language learners outside the classroom through the provision of resources and spaces, spans more than five decades and is currently in a phase that Mynard (2019a) refers to as the 'basic psychological needs and wellbeing' phase. This is a turning point in SALL wherein the focus has shifted towards the need for (more explicitly) facilitating an autonomy-supportive environment outside the classroom. This focus supports language learners' needs for autonomy, relatedness and competence, and as such, aims to provide the conditions needed to foster language learning in an environment in which they can thrive and grow in psychologically healthy ways (Ryan & Deci, 2020). In this theoretical article, the authors make a case for using self-determination theory (SDT; Deci & Ryan, 1985; Ryan & Deci, 2017) as an overarching framework for future developments in the field of SALL. The article gives an overview of four key SALL support systems, showing how they can fulfil students' basic psychological needs. These four key support systems are: advising in language learning; structured awareness raising; conversation lounges; and interest-based, student-led learning communities.
