“…For example, people who are afraid of, or anxious about failure in challenging and demanding situations, and therefore seek to avoid them, are shown to be low achievers (Jones & Berglas, 1978; Midgley, Arumkumar & Urdan, 1996; Miller, 1987). On the other hand, those who are optimistic and make an active effort to deal with a challenging situation turn out to be high achievers (Aspinwall & Taylor, 1997; Cantor, 1990; Diener & Dweck, 1978; Hokoda & Fincham, 1995; Hokoda, Fincham & Diener, 1989; Pintrich & DeGroot, 1990). Another important factor that has been shown to influence adolescents’ academic achievement and problems at school is their peers and friends.…”
