In an effort to understand the temporal organization of infant physiologic and behavioral systems during social interaction with adults, spectral and cross-spectral analyses of infant heart rate and mother-father-stranger-infant behavioral data are described herein for a 3-month-old infant during face-to-face social interaction with her parents and a stranger. This infant's heart rate rhythms were stronger during social interaction with both mother and father than with a stranger. Infant behavioral rhythms were associated with (high coherence) the parents' behavioral rhythms, but not with those of the stranger. Furthermore, infant heart rate and infant behavioral rhythms showed high coherence with all three adults. Although these findings are preliminary, based on a case study and need replication, they generate intriguing hypotheses. This technique of studying the rhythmicity of infant social interaction with spectral analysis suggests that the 3-month-old infant's behavior and heart rate are synchronized during interaction with all three adults; however, the infant and adult behavioral rhythms are synchronous only with mother and father and not with an unfamiliar stranger.
为了了解婴儿在与成人社交互动过程中生理和行为系统的时间组织，本文描述了对一名3个月大婴儿在与父母及一名陌生人进行面对面社交互动时的心率以及母婴-父婴-陌生婴儿行为数据进行的频谱分析和互谱分析。与陌生人相比，该婴儿在与母亲和父亲的社交互动过程中心率节律更强。婴儿的行为节律与父母的行为节律相关（高相干性），但与陌生人的行为节律无关。此外，婴儿心率和行为节律与所有三位成人都表现出高相干性。尽管这些发现基于一项案例研究，尚属初步且需要重复验证，但它们提出了有趣的假设。这种通过频谱分析研究婴儿社交互动节律性的技术表明，3个月大的婴儿在与所有三位成人互动时其行为和心率是同步的；然而，婴儿与成人的行为节律仅在与母亲和父亲互动时同步，与不熟悉的陌生人互动时则不同步。
