從節奏到意義：早期手勢與語言發展多模態前驅指標的縱向研究

// From rhythms to meaning: Longitudinal evidence on multimodal precursors of early gestures and language development

本縱向研究追蹤2至12個月嬰兒，觀察其自發動作、節奏動作與手勢發展｜發現自發動作3個月後減少，節奏動作於6至9個月達高峰，手勢在第一年最後三個月增加｜節奏動作與9個月時的詞彙量有正相關，顯示其在嬰兒早期溝通基礎中扮演重要角色。

// This longitudinal study observed infants aged 2-12 months to examine the development of spontaneous movements, rhythmic movements, and gestures during interactions with adults and objects. Using microanalytic coding, the study found that spontaneous movements decrease after three months, rhythmic movements peak between 6-9 months, and gestures increase in the last trimester of the first year. Multimodal combinations of gestures and vocalizations were rare and stable, with rhythmic movements correlating with vocabulary at 9 months. The results suggest infant expressive development reorganizes motor behaviors over time, with rhythmic movements playing a key role in early communication foundations.
