In this paper, we started reviewing the relationship between personality traits and personal values. And then, we focused the abstract and concrete thinking style, the growth mindset, and the promotion-focused fit as the students’ personality traits. Also, we focused the future time perspective as the students’ personal value. All these factors have temporal features, especially future, in a sense. Abstraction is related to distant future positively [23]. The growth mindset is related to the possibility of the intelligence development in the future [5]. The promotion-focused people act for the future positive outcome (goal-oriented) [8]. The addiction is also related to the present in a temporal aspect. Thus, we found out that the three cognitive traits affect the future time perspective, and then all the factors except the promotion-focus affect the smart phone addiction negatively. One of the features of the promotion-focus is related to risk-taking [24]. The risk-taking is also related to the present hedonic time perspective. This feature lowered the relationship between the promotion-focus and the smart- phone addiction.
As already mentioned in the Introduction Section, the adolescent is more vulnerable to technology addiction than adults. Thus, technology addiction is a quite serious problem to them. In order to prevent the addiction problem, educators should devise new methods for our adolescent to have a long time horizon.
