This study examined parental behaviors (autonomy support, control) toward their adolescent child as well as parents' and adolescents' positive and negative emotions experienced during parent-adolescent discussions on vocational decision-making. Research showed that repeated daily interactions provide the seeds to stable interactional patterns. Exploring short-term interactions allows to understand the process of behavioral and emotional change that takes place during discussions. Thus, a first goal was to identify and describe parental behaviors and emotions manifested by parents and adolescents during this discussion. Second, using a multilevel modeling approach, dynamic structural equation modeling (DSEM), simultaneous associations between parental behaviors and emotions were examined. The third goal was to examine the extent to which parental behaviors and parents' and adolescents' emotions predicted each other during this discussion. Parent-adolescent dyads (N = 42) participated in a discussion task on the adolescent's career choice, where parental behaviors were rated by observers, and emotions were detected with a facial expression recognition software. Results showed that parental autonomy is beneficial for adolescents in the short term (reduction of negative emotions). Also, the results showed that adolescents' emotions influence parental behaviors, suggesting that adolescents play an active role in the co-construction of their vocational project by leading the parent to adopt specific behaviors during the discussion. Finally, the emotions of parents and adolescents were dynamically interrelated, which indicates emotional contagion. These findings highlight the necessity to consider momentary parental behaviors and emotions to better understand parental contributions in vocational development.

本研究调查了父母对青春期孩子的行为（自主支持、控制）以及父母和青少年在职业决策讨论中父母和青少年的积极和消极情绪。研究表明，每天重复的互动为稳定的互动模式奠定了基础。探索短期互动可以了解讨论期间发生的行为和情绪变化的过程。因此，第一个目标是确定和描述父母和青少年在讨论期间表现出的父母行为和情绪。其次，使用多层次建模方法、动态结构方程模型 (DSEM)，研究了父母行为与情绪之间的同时关联。第三个目标是检查在讨论过程中父母行为与父母和青少年情绪相互预测的程度。父母-青少年二元组（否 = 42) 参与了一项关于青少年职业选择的讨论任务，观察者对父母的行为进行评分，并使用面部表情识别软件检测情绪。结果表明，父母的自主权在短期内对青少年有益（减少负面情绪）。此外，结果表明，青少年的情绪会影响父母的行为，这表明青少年通过在讨论中引导父母采取特定行为，在共同构建他们的职业项目中发挥了积极作用。最后，父母和青少年的情绪是动态相关的，这表明情绪会传染。
