“…Previous studies have shown that both FTP and PI are related with important educational variables such as student motivation (Creten, Lens, & Simons, & 2001;Husman & Lens, 1999;Simons, Dewite, & Lens, 2004), school investment (Peetsma, 2000), academic engagement (Horstmanshof & Zimitat, 2007), and academic achievement (Adelabu, 2007;De Volder & Lens, 1982;Malka & Covington, 2005;Teahan, 1958;Zimbardo & Boyd, 1999). In one of the earlier studies, Teahan (1958), for example, found that high achievers have more extensive (i.e., refers to the subjective time horizon by which people's forethought is limited) FTP than low achievers on most of the projective tests such as story completion tests and Thematic Apperception Tests.…”
