The capacity for dynamically coordinating behaviour is assumed to have largely matured in infancy. In adolescence—another sensitive period for social development—the primary focus on individual social cognition as the main driver of interaction has prevented the study of actual social interaction as behavioural coordination within dyads. From a dynamic perspective, however, capturing real-time social dynamics is essential for the assessment of social interactive processes. In order to improve the understanding of social development during adolescence, we investigated the potential developmental course of social contingency detection in dynamic interactions. Pairs of 205 Belgian adolescents (83 male, 122 female), aged 11–19, engaged in real-time social interaction via the Perceptual Crossing Experiment (PCE). Comparing early, middle and late adolescents, we found a generally higher performance of late adolescents on behavioural and cognitive measures of social contingency detection, while the reported awareness of the implicitly established social interaction was lower in this group overall. Additionally, late adolescents demonstrated faster improvement of behavioural social coordination throughout the experiment, compared with the other groups. Our results indicate that social interactive processes continue to develop throughout adolescence, which manifests as faster social coordination at the behavioural level. This finding underscores dynamic social interaction within dyads as a new opportunity for identifying altered social development during adolescence.

社会突发事件检测能力在整个青春期持续发展

动态协调行为的能力被认为在婴儿期已经基本成熟。在青春期——社会发展的另一个敏感时期——主要关注个人作为互动的主要驱动力的社会认知阻碍了将实际社会互动作为二元内行为协调的研究。然而，从动态的角度来看，捕捉实时社会动态对于评估社会互动过程至关重要。为了提高对青春期社会发展的理解，我们研究了动态互动中社会偶然性检测的潜在发展过程。11-19 岁的 205 名比利时青少年（83 名男性，122 名女性）通过感知交叉实验 (PCE) 进行实时社交互动。比较早期、中期和晚期青少年，我们发现晚期青少年在社会意外事件检测的行为和认知测量方面的表现普遍较高，而报告的对隐性建立的社会互动的认识在这个群体中总体较低。此外，与其他组相比，晚期青少年在整个实验过程中表现出更快的行为社会协调改善。我们的研究结果表明，社会互动过程在整个青春期继续发展，这表现为行为水平上更快的社会协调。这一发现强调了二元组内的动态社会互动是识别青春期改变的社会发展的新机会。我们的研究结果表明，社会互动过程在整个青春期继续发展，这表现为行为水平上更快的社会协调。这一发现强调了二元组内的动态社会互动是识别青春期改变的社会发展的新机会。我们的研究结果表明，社会互动过程在整个青春期继续发展，这表现为行为水平上更快的社会协调。这一发现强调了二元组内的动态社会互动是识别青春期改变的社会发展的新机会。
