It is my privilege to work as a tertiary learning advisor (TLA). Through my role I have had the opportunity to form unique relationships with students during individual consultations. This has enabled me to observe student behaviour, and the metacognitive strategies students use to negotiate the myriad challenges of tertiary study. I noticed trends in student behaviour that did not fit current literature on teaching and learning, and identified possible links between the observed student feelings of overwhelm, and sensory processing sensitivity (SPS) and highly sensitive people (HSP), the term used to describe humans with SPS. This paper examines the transformative journey I took in identifying the key indicators of SPS, firstly in myself, and then in my students. My burgeoning knowledge and reflection on and in my own practice provided self-scaffolding that enabled me to recognise and share the markers of SPS. My study "Does an understanding of HSP help students who identify as Highly Sensitive People (HSP) to manage their learning?" found that HSP students unanimously rate the knowledge of SPS to be life-changing and empowering in managing life and study. All participants also believed that information about SPS should be made available to all in-coming students, and that tutors should be given training and resources in order to better support HSP students. Of significance, it also found that tertiary students with SPS have often already developed useful metacognitive strategies for independent and life-long learning by the time they reach tertiary level education.
