Mental time travel is comprised of mental reconstruction from personal past events (episodic memory), as well as mental construction from possible future events (foresight) (Suddendorf & Corballis, 1997). Recent findings suggest that both episodic memory and the self can contribute to shape the episodic future thinking (foresight). However, how self-concept may make the process different is not yet fully understood (Shao, Yao, Ceci & Wang, 2010). The current two studies therefore aim to explore the dynamics between the self and mental time travel. The first study investigated how core self-evaluations can be related to mental time travel, by showing whether the self-concept can predict episodic future thinking. Sixty undergraduates completed 4 questionnaires (self-esteem, self-efficacy, locus of control and neuroticism) to evaluate their core self-concepts. Each of them had to either recall past experiences or simulate future scenarios by 4 various aspects (autobiographical fluency, autobiographical specificity, amount of episodic details and phenomenology). A series of correlation analyses and stepwise regression analyses were conducted. The main results show that reported frequencies at future imagination are significantly predicted by past autobiographical fluency (β = .60，p < .001, R2 = .44) and self-esteem (β = .30，p < .005, R2 = .09). Furthermore, the self-efficacy (β = .36，p < .01, R2 = .13) rather than past events can predict the subjective feeling at future events imagination (phenomenology). The second study further explored whether the episodic future thinking can be shaped by different self-construal. Sixty undergraduates were randomly assigned to one of two groups: interdependent or independent self-concept. Participants assigned in each of these groups were presented with a story either focused on self or others. Six questions were further asked to confirm the priming effect. The follow-up interview involved topics in terms of autobiographical specificity, personal focus of past/future events, and phenomenal characteristics. To examine whether the self-construal would affect mental time travel, five repeated measure analyses of variance (ANOVAs) with time (past vs. future) as a within-subject factor, and self-construal (interdependent vs. independent) as a between-group factor were conducted. The main results show : (1) Those in the interdependent self-concept group reported more specific past and future experiences than those in the independent group, F(1,58) = 6.51，p < .05，ηp2 = .10; (2) Those in the interdependent self-concept group reported more information about others and relationships, whereas those in the independent self-concept group described more details about themselves, F(1,58) = 9.36，p < .005，ηp2 = .14; (3) Those in the independent self-concept group gave higher scores at evaluating their subjective feelings, expressing more richness and vividness of episodic details than the other group, F(1,58)= 5.27，p < .05，ηp2 = .08. These findings suggest that the self-concept can drive the construction of past and future events. Our studies reveal the dynamics between the self and mental time travel from a novel perspective.
