In this first issue of "The Journal for the Psychology of Language Learning," this paper discusses some of methodological issues surrounding research methodology on emotions in the field of applied linguistics and language learning research. The aim of this paper is to develop a basic understanding and awareness of the challenges and issues involved in conducting research on emotions by bringing the notion of researcher's reflexivity to the forefront. Studies on researcher's reflexivity in any empirical research is nothing new, but how it is actually incorporated and manifested in the research process is a fairly neglected matter. The purpose of this paper is thus to pursue this matter by revisiting one of author's previous research that explores emotions in conjunction with its related and intertwining factors such as identity, L2 self, positionality and learners' language learning experiences.
