The Perceptual Crossing Experiment (PCE) captures the capacity for social contingency detection using real-time social interaction dynamics but has not been externally validated. We tested ecological and convergent validity of the PCE in a sample of 208 adolescents from the general population, aged 11 to 19 years. We expected associations between PCE performance and (a) quantity and quality of social interaction in daily life, using Experience Sampling Methodology (ESM; ecological validity) and (b) self-reported social skills using a questionnaire (convergent validity). We also expected PCE performance to better explain variance in ESM social measures than self-reported social skills. Multilevel analyses showed that only self-reported social skills were positively associated with social experience of company in daily life. These initial results do not support ecological and convergent validity of the PCE. However, fueled by novel insights regarding the complexity of capturing social dynamics, we identified promising methodological advances for future validation efforts.

感知交叉实验（PCE）利用实时社交互动动态捕获社交意外事件检测的能力，但尚未得到外部验证。我们以来自一般人群的 208 名 11 至 19 岁青少年为样本，测试了 PCE 的生态效度和收敛效度。我们预计 PCE 表现与（a）日常生活中社交互动的数量和质量（使用经验抽样方法（ESM；生态效度））和（b）使用问卷（收敛效度）自我报告的社交技能之间存在关联。我们还预计 PCE 表现比自我报告的社交技能能够更好地解释 ESM 社会衡量指标的差异。多层次分析表明，只有自我报告的社交技能与日常生活中公司的社交经历呈正相关。这些初步结果并不支持 PCE 的生态和收敛有效性。然而，在关于捕捉社会动态的复杂性的新见解的推动下，我们发现了未来验证工作有希望的方法论进展。
