The current study identified career-development profiles in a sample of 4815 Chinese adolescents (M_age = 16.19 years, SD = 0.67) and examined their associations with academic self-efficacy and academic motivation. The latent profile model was built on four facets of career development (career feeling, career belief, career exploration, and career planning). The results identified three profiles: high career exploration and planning (N = 225, 6.00%), low career development (N = 907, 22.13%), and average career development (N = 3224, 71.91%). Those showing high career exploration and planning showed significantly higher levels of academic self-efficacy and academic motivation than those showing the other two profiles. The results indicated non-monotonous patterns and asynchronous associations and developmental trajectories among the facets of career development among adolescents. Important implications for career education can be drawn based on the findings from the relations among career-development profiles, academic self-efficacy, and academic motivation.

Mindfulness appears to improve empathy and understanding in relationships, which are necessary for successful cooperation. However, the impact of mindfulness on cooperation has not been fully studied. This study used hyperscanning technique to examine the effect of mindfulness on the inter-brain synchrony of interacting individuals during the cooperative tasks. Forty-one dyads were randomly assigned to a mindfulness group or a non-mindfulness group. Dyads of the mindfulness group performed a short mindfulness exercise following a 15-minute mindfulness audio guidance. Dyads of the non-mindfulness group were instructed to rest quietly with their eyes closed. Then, simultaneously and continuously EEG was recorded from all dyads when they completed a computer-based cooperative game task. Reaction times (RTs) and success rates were used to indicate the behavioral performance, and phase locking value (PLV) was used to indicate the inter-brain synchrony. The results showed that (1) Greater theta inter-brain synchrony during the cooperative computer game tasks was observed in the mindfulness group than in the non-mindfulness group; (2) Greater theta inter-brain synchrony was observed in the successful cooperation conditions as compared to those in the failure cooperation conditions; (3) Greater theta inter-brain synchrony was observed at the frontal region as compared to those at the parietal-occipital region in the successful cooperation condition. The results expand the neural basis of the effects of mindfulness on cooperation feedback processing.

Background: The interaction between parent and adolescent is more challenging than in other age periods. Family cohesion seriously impacts parent-adolescent emotional interactions. However, the underlying neural mechanism has not been fully examined. This study examined the differences in the neural synchrony in response to emotional film clips between high and low family cohesion adolescent-parent dyads by using the electroencephalograph (EEG) hyperscanning. Results: Simultaneously electroencephalograph (EEG) was recorded while 15 low family cohesion parent-adolescent dyads (LFCs)and 14 high family cohesion parent-adolescent dyads (HFCs)received different emotional induction when viewing film clips. Interbrain phase-locking-value (PLV) in gamma band was used to calculate parent-adolescent dyads’ interbrain synchrony. Results showed that higher gamma interbrain synchrony was observed in the HFCs than the LFCs in the positive conditions. However, there was no significant difference between the HFCs and LFCs in other conditions. Also, the HFCs had significantly higher gamma interbrain synchrony in the positive conditions than in the negative conditions. Conclusion: Interbrain synchrony may represent an underlying neural mechanism of the parent-adolescent emotional bonding, which is the core of family cohesion.

Numerous studies have suggested that academic stress has negative impact on adolescents’ psychological function, few of those studies, however, considered whether and how the impact of stress on adolescents’ emotional states is moderated by corresponding regulation. This study aimed to examine the fluctuation of emotional states before and after the mid-term examination and the influence of different emotional regulatory strategies. In the present study, 72 adolescents aged 12–18 reported their emotional states and corresponding regulation before and after mid-term examination up to six times over a period of two weeks. Results showed that: (a) On the sampling day, the participants reported increasingly emotional states as time went by. Improvement of adolescents’ daily emotional states was more significant after the mid-term examination. Participants reported decreasingly positive emotional states and increasingly negative ones as time went by before mid-term examination. (b) Adolescents who used down-regulation at a certain sampling moment reported more pleasant emotional states at the subsequent sampling moment than those who used up-regulation. Adolescents who used more up-regulation in a negative emotional event reported more negative emotional states at the subsequent sampling moment after the mid-term examination.

Healthy peer relationships could provide emotional and social support for adolescents experiencing dramatic physical and environmental changes. Examining age differences in cognitive neural processing during peer interaction provides insight into adolescent interpersonal contact and “social brain” development. The present study compared the age differences between adolescents and adults by examining the behavior and interbrain synchronization of pairs in a cooperative computer game task. 32 pairs of adolescents and 31 pairs of adults were recruited as participants. The reaction times and interbrain synchronization of the participants were measured. The results revealed that interbrain synchronization activation following the onset of the “ready signal” was primarily detected in low-frequency bands such as delta and theta. Adolescent pairs’ interbrain synchronization activations were significantly higher than those of adult pairs in the anterior and central brain regions, such as the frontal, frontal-central, and parietal lobes. Correlation analysis indicated a positive correlation between occipital region interbrain synchronization and behavioral performance. The findings provide behavioral and neurophysiological evidence for the characteristics of adolescent interpersonal cognitive processing and point to the significance of low-frequency interbrain synchronization in interpersonal coordination.
