Socioemotional and referential communication are primary expressions of interpersonal engagement in infancy and beyond. Early socioemotional communication in dyadic interactions may form a foundation for triadic referential communication and gesture production, yet the role of temperament in moderating their association has not been examined. We investigated whether early socioemotional communication behaviors, and infant temperamental reactivity, were associated with later pointing production. Participants were 51 infants (45% girls) and both their parents (86.5% Dutch). Early infant socioemotional communication (production of smile, vocalizations, and gaze) was observed during separate home-based face-to-face interactions with mothers, fathers, and strangers at 4 and 8 months. At both ages, mothers and fathers reported on infant temperamental surgency and negative affectivity, and overall means were calculated. Referential communication (declarative pointing) was measured during structured lab-based observations at 12 and 15 months. Socioemotional and referential communication behaviors were microanalytically coded second by second. Poisson multilevel regression analyses indicated interaction effects between temperament and smile, vocalizations, and gazes to the adult's face with each partner in predicting pointing. High levels of infant temperamental surgency tended to enhance positive associations between early socioemotional communication behaviors with mothers and fathers and pointing. By contrast, high levels of negative affectivity tended to dampen associations between early communication behaviors with strangers and pointing. Results highlight the importance of infant socioemotional communication with diverse partners and the moderating role of temperamental reactivity in predicting referential communication.

社交情感和指代性交流是婴儿期及以后人际互动的主要表现形式。在双人互动中，早期的社交情感交流可能为三人参照交流和手势产生奠定基础，但气质在调节它们之间的关联中的作用尚未得到检验。我们研究了早期社交情感交流行为和婴儿气质反应性是否与后期的指点产生有关。参与者为 51 名婴儿（45%为女孩）及其父母（86.5%为荷兰人）。在 4 个月和 8 个月时，分别在婴儿家中进行了面对面的独立互动，观察了婴儿与母亲、父亲和陌生人的早期社交情感交流（微笑、发声和注视的产生）。在这两个年龄段，母亲和父亲都报告了婴儿气质的易激惹性和负向情感，并且计算了总体平均值。在 12 个月和 15 个月时，通过结构化的实验室观察测量了参照性交流（宣告性指点）。社交情感和参照性交流行为被逐秒进行微观分析编码。泊松多级回归分析表明，在预测指向时，气质与对每个成人面孔的微笑、发声和注视之间存在与同伴的交互作用。婴儿气质易激惹性水平较高，往往会增强婴儿与母亲和父亲的早期社交情感交流行为与指点之间的正相关关系。相比之下，负向情感水平较高往往会削弱婴儿与陌生人的早期交流行为与指点之间的关联。结果强调了婴儿与不同同伴的社交情感交流的重要性，以及气质反应性在预测参照性交流中的调节作用。（PsycInfo 数据库记录（c）2024 APA，保留所有权利）。
