Positive academic emotions can promote good academic performance and development in students. Therefore, how teachers stimulate students to produce more positive academic emotions is particularly important. This study aimed to reveal the underlying mechanism of teacher support and adolescents’ positive academic emotions. A total of 854 students from western China participated in this survey, which included the Students’ Perception of the Teacher’s Behavioural Support Questionnaire, the Psychological Suzhi Questionnaire for Middle School Students, the General Self-Efficacy Scale, and the Achievement Emotions Questionnaire (396 boys; 12 to 20 years old, M_age = 15.3, SD = 2.04). Results showed that (1) teacher support, psychological suzhi, and general self-efficacy were positively correlated with students’ positive academic emotion; (2) psychological suzhi and general self-efficacy played a separate mediating role between teacher support and adolescents’ positive academic emotion; and (3) teacher support also influenced adolescents’ positive academic emotion through the serial mediation of psychological suzhi and general self-efficacy.

Prosocial behavior contributes to the well-being of individuals as well as the harmonious development of society. This research aimed to reveal the mechanisms underlying the relationship between the psychological suzhi and prosocial behavior of Chinese adolescents with the consideration of time. A total of 477 adolescents (228 boys, 49.1%; M_age = 14.04 and SD = 1.77) from southwest China completed three questionnaires during waves 1 and 2. Results showed that psychological suzhi and forgiveness were positively correlated with prosocial behavior in both waves 1 and 2; psychological suzhi significantly predicted both current and three months later prosocial behavior and forgiveness played a mediating role in both immediate and lasting effects of psychological suzhi on prosocial behavior. Psychological suzhi and forgiveness are vital predictors of adolescents’ prosocial behaviors in China. Interventions based on psychological suzhi and forgiveness are essential to promote the development of pro-social behaviors.

Detecting and correcting execution errors is crucial for safe and efficient goal-directed behavior. Despite intensive investigations on error processing, the cognitive foundations of this process remain unclear. Based on the presumed relation between executive attention (EA) and error processing, we implemented a seven-day EA intervention by adopting the Posner cueing paradigm to test the potential causal link from EA to error processing in healthy adults. The experimental group (high EA, HEA) was trained on the Posner cueing paradigm, with a ratio of invalid cue (IC) trials to valid cue (VC) trials of 5:1 and a corresponding ratio of 1:1 in the active control group (low EA, LEA). We found that the EA intervention improved EA across intervention sessions. Critically, after the EA intervention, the HEA group showed that post-error accuracy (PEA) was restored to the same level as the post-correct accuracy (in comparison with the LEA group). However, post-error slowing and the flanker effect were not modulated by the EA intervention. Furthermore, we observed that the changes in the accuracy of VC trials positively predicted the changes in PEA and that the two groups were classified according to the changes in PEA with a 61.3% accuracy. Based on these results, we propose that EA causally drives error processing. And the capabilities of the “actively catch” more attention resources and the automatic mismatch processing developed after EA intervention is transferable to error processing, thereby directly resulting in the gains in post-error adjustments. Our work informs the potential cognitive mechanisms underlying this causal link.
