摘要:Abstract With this paper, the author has two main objectives: (i) to reflect on the role of emotions regarding the process of PhD research and supervision, and (ii) to identify the emotions mature students experience through their engagement in a research-based PhD, considering their own voices gathered through an in-depth focus group. The pertinence of this subject is grounded on two main reasons. On the one hand, a hot reality may be verified in different parts of the globe: mature students engaging in research-based PhDs. On the other hand, small research has been addressing the role of emotions in the supervisory and research processes, even though this experience has been considered, for many PhD students, an intense and demanding ‘roller coaster’.
