The relationships between the temporal focus of mind-wandering (i.e., past-oriented and future-oriented mind-wandering) and well-being are important issues for adolescents, which may have significant implications on their well-being and self-identity development. However, few studies tested the temporal focus of mind-wandering and its emotional consequences in adolescents. In the present study, we conducted two studies using self-reported questionnaires from large sample sets to examine the relationships between the temporal focus of mind-wandering and hedonic (pleasure attainment) and eudaimonic (meaning pursuing) well-being among Chinese adolescents. Study 1 preliminarily tested the relationships between the temporal focus of mind-wandering and hedonic well-being among adolescents ( n = 1273) suggesting that both past-oriented mind-wandering (PMW) and future-oriented mind-wandering (FMW) were positively correlated with hedonic well-being. Study 2 used a new sample ( n = 986) and included another aspect of well-being (i.e., eudaimonic well-being), showing that PMW and FMW were both positively correlated with hedonic and eudaimonic well-being. Moreover, self-reflection mediated the relationships between FMW and hedonic/eudaimonic well-being, whereas self-reflection did not act as a mediator in the relationships between PMW and well-being. The present findings indicated that both PMW and FMW are beneficial for Chinese adolescents' well-being, and emphasized the mediating role of self-reflection in the relationships between FMW and well-being.

Rewards play an important role in people's well-being. However, the mechanisms underlying neural habituation to hedonic rewards (attainment of pleasure) and eudaimonic rewards (attainment of meaning and self-realization) and their implications for longitudinal changes in well-being remain unknown. By operationalizing hedonic rewards as "winning money for oneself" and eudaimonic rewards as "winning money for a charity", 78 participants (41 women, aged from 17 to 24 years) completed a revised monetary gambling task during event-related potential (ERP) recording. Subsequently, the participants' well-being was measured after one year. The results showed that the reward positivity (RewP) effect readily decreased as the hedonic rewards were repeated, whereas the RewP effect in response to eudaimonic rewards was relatively sustained over time. Moreover, the declining RewP effect for repeated eudaimonic rewards was marginally positively associated with longitudinal decreases in well-being. These findings demonstrate at the neural level that sensitivity to repeated hedonic rewards is more prone to decrease than sensitivity to repeated eudaimonic rewards, and sustained eudaimonic reward sensitivity in the short term has greater implications for changes in well-being in the long term., (© 2021 Society for Psychophysiological Research.)

Reward or pleasure can be achieved from a hedonic approach (pleasure attainment) or eudaimonic approach (meaning and self-realization). However, the neurodynamics of hedonic and eudaimonic reward processing remain unclear. By operationalizing hedonic reward as "win money for oneself" and eudaimonic reward as "win money for charity", the current study used the monetary incentive delay task to parse hedonic and eudaimonic reward dynamics into the anticipatory and consummatory stages while event-related potentials (ERPs) were recorded. 24 participants (12 women) were recruited in this study. The results showed that in the anticipatory stage, the amplitudes evoked by hedonic and eudaimonic reward did not differ during early cue recognition (P2, N2), but they separated during late cue elaboration (cue-P3). In the consummatory stage, hedonic reward elicited a larger FRN effect, but eudaimonic reward elicited a larger fb-P3 effect. In addition, we also used the neural indices of hedonic and eudaimonic reward processing to predict participants' longitudinal changes in well-being (depression and positive emotion) across 6 months as exploratory in nature. Preliminary regression evidence suggested that greater differential amplitude of cue-P3 elicited by eudaimonic reward anticipation versus neutral anticipation positively predicted longitudinal increases in positive emotion. The findings elucidated specific substages of hedonic and eudaimonic reward processing and explored their potential roles in longitudinal changes in well-being., (Copyright © 2018 Elsevier B.V.

What is a good life and how it can be achieved is one of the fundamental issues. When considering a good life, there is a division between hedonic (pleasure attainment) and eudaimonic well-being (meaning pursuing and self-realization). However, an integrated approach that can compare the brain functional and structural differences of these two forms of well-being is lacking. Here, we investigated how the individual tendency to eudaimonic well-being relative to hedonic well-being, measured using eudaimonic and hedonic balance (EHB) index, is reflected in the functional and structural features of a key network of well-being-the default mode network (DMN). We found that EHB was positively correlated with functional connectivity of bilateral ventral medial prefrontal cortex within anterior DMN and bilateral precuneus within posterior DMN. Brain morphometric analysis showed that EHB was also positively correlated with gray matter volume in left precuneus. These results demonstrated that the relative dominance of one form of well-being to the other is reflected in the morphometric characteristics and intrinsic functions of DMN., (© The Author (2017).
