“…Specifically, due to their strong motivation to achieve their goals (Brown et al, 2006; Steins & Behravan, 2017), graduate students with high proactive personality are more likely to feel the full support of their tutors during their daily interaction with their tutors (Eid & Al‐Jabri, 2016; Majid & Wey, 2009; Ozkurt & Alpay, 2018), and they are more active in participating in knowledge sharing activities. In contrast, graduate students with low proactive personality miss out on opportunities because of their passivity in interacting with their tutors (Hosseingholizadeh & Khoniki, 2015; Reeve, 2006), and even in a good teacher−student relationship, they often display a negative attitude, fail to recognize the learning opportunities provided by their tutors, and are less likely to share knowledge (Hughes et al, 2001; Robertson, 2020). Therefore, under the influence of mentor−student relationship, graduate students with high proactive personality can show stronger knowledge sharing willingness and knowledge sharing behavior than individuals with low proactive personality.…”
