It plays an important role in establishing life plans and projects. An individual with a vast time perspective can more easily articulate far-reaching goals as well as obtain resources to achieve them. Additionally, undertaken present actions often have immediate as well as long-term effects and the ability to anticipate them is important. Both aspects are necessary for life success. The goal of this study was to validate the two following hypotheses. The first stipulates that a developed future time perspective (PPC) is related to the ability to consider future consequences (CFC). The second hypothesis states that the development of formal operatory thought favours the formation of both aforementioned characteristics. A total of 127 students from 5 fi rst-year secondary school classes participated in the survey in which each completed a FTP test and the CFC Scale. The presented CFC Scale was adapted to serve the purpose of this study. The results verify that PPC and CFC are strongly correlated (0.73). Furthermore, the level of formal thinking (measured by the Test of Formal Operations) has a signifi cant meaning for FTP (F(2, 124) = 52.73; p
