Abstract

Positive social bidding refers to moments when infants look at an unresponsive caregiver and try to re-engage the social partner via smiling and/or vocalizing. Prior to six months of age, there is considerable variability in the extent to which infants engage in positive social bidding. In this study we explore whether infants' and mothers' cardiac vagal tone is associated with these individual differences. Mothers and their 4- to 6-month-old infants (n = 132) participated in the Face-to-Face Still-Face Paradigm (FFSF); social behaviors and respiratory sinus arrhythmia (RSA) were recorded on a moment-to-moment basis. More frequent vocal bidding during the Still-Face episode was related to infants' and mothers' physiological synchrony, as well as lower levels of infants' negative affect and higher levels of infants' RSA during face-to-face Social Play. Also, infants demonstrating more vocal bidding exhibited greater increases in RSA at the beginning and end of the Reunion phase following the Still-Face stressor. Critically, the relation between infants' physiological regulation and vocal bidding differed as a function of the FFSF episode in which RSA was measured. The implications of adopting a biobehavioral perspective on the development of positive social bidding are discussed.

静止面孔范式下婴儿社会竞价行为的生物行为关联

积极的社会竞价指的是婴儿看着一个没有反应的照顾者，并试图通过微笑和/或发声来重新吸引社会伙伴的时刻。在六个月之前，婴儿参与积极社会竞价的程度有相当大的差异。在这项研究中，我们探讨了婴儿和母亲的心脏迷走神经张力是否与这些个体差异有关。母亲及其4 ~ 6个月大的婴儿（n = 132）参与了face - face - face范式（FFSF）；即时记录社会行为和呼吸性窦性心律失常（RSA）。静止面孔事件中更频繁的语音命令与婴儿和母亲的生理同步性有关，也与面对面社交游戏中婴儿的负向情感水平降低和婴儿的RSA水平升高有关。此外，表现出更多声音竞价的婴儿在“静止面孔”应激源后的重聚阶段的开始和结束时，RSA表现出更大的增长。至关重要的是，婴儿的生理调节和发声竞价之间的关系在测量RSA的FFSF事件中有所不同。采用生物行为学的观点对发展积极的社会投标的影响进行了讨论。

期刊介绍： Infancy, the official journal of the International Society on Infant Studies, emphasizes the highest quality original research on normal and aberrant infant development during the first two years. Both human and animal research are included. In addition to regular length research articles and brief reports (3000-word maximum), the journal includes solicited target articles along with a series of commentaries; debates, in which different theoretical positions are presented along with a series of commentaries; and thematic collections, a group of three to five reports or summaries of research on the same issue, conducted independently at different laboratories, with invited commentaries.
