Learning a language is a long-term undertaking. In this endeavor, motivation is served by patterns of regulation that steer and control behavior. Regulation can be focused on possibilities and opportunities (an approach pattern), or the implications of failure (an avoidance pattern). Responding to calls for work with a focus on regulation (Papi et al., 2019), and with the aim of developing insights into second-language perseverance, this study explores the regulation profiles of highly motivated adult learners of Swedish. Using the directed motivational currents construct as a template, analyses of interview data from 18 participants revealed distinct patterns of approach- and avoidance-focused regulation. While approach orientations were associated with enjoyment and well-being, avoidance orientations were associated with worry and stress. The effects of regulatory orientations on motivational sustainability are discussed, and implications for theory and practice are considered. © National Federation of Modern Language Teachers Associations
