The embodiment approach has shown that motor neural networks are involved in the processing of action verbs. There is developmental evidence that embodied effects on verb processing are already present in early years. Yet, the ontogenetic origin of this motor reuse in action verbs remains unknown. This longitudinal study investigates the co-occurrence of manual verbs and actions during mother-child daily routines (free play, bathing, and dining) when children were 1 to 2 (Group 1) and 2 to 3 (Group 2) years old. Eight mother-child dyads were video-recorded in 3-month intervals across 12 months (27 recording hours), and the timing of verbs and manual actions (21,876 entries) were coded by independent observers. Results showed that the probability of matched verb-action co-occurrences were much higher (0.80 and 0.77) than that of random co-occurrences (0.13 and 0.15) for Group 1 and Group 2, respectively. The distributions of the verb-action temporal intervals in both groups were quite symmetrical and skewed with the peak corresponding to both 0.00 s synchronic intervals (8% of the cases) and the shortest +5 s interval (40% of the cases). Mother-led instances occurred in both groups whereas child-led instances were restricted to Group 2. Mothers pragmatically aligned their verbal productions, since they repeatedly used (74%) those verbs they shared with their children's repertoire (31%). In conclusion, the early multisensory communicative and manipulative scene affords grounding of verb meanings on the ongoing actions, facilitating verb-action pairing in the realm of social interactions, providing a new dimension to the prevailing solipsistic approach to embodiment.
具身认知方法表明，运动神经网络参与了动作动词的处理。有发展证据表明，早年就已存在具身认知对动词处理的影响。然而，这种动作动词中运动复用的个体发生起源仍然未知。这项纵向研究调查了1至2岁（第1组）和2至3岁（第2组）儿童在母子日常活动（自由玩耍、洗澡和用餐）中手动动词和动作的共现情况。8对母子在12个月内每隔3个月进行一次视频记录（共27个记录小时），独立观察者对动词和手动动作的时间（21876条记录）进行编码。结果显示，第1组和第2组中，动词与动作匹配共现的概率分别比随机共现的概率（0.13和0.15）高得多（0.80和0.77）。两组中动词 - 动作时间间隔的分布相当对称且有偏差，峰值对应于0.00秒同步间隔（占案例的8%）和最短的 +5秒间隔（占案例的40%）。两组中都出现了母亲主导的情况，而儿童主导的情况仅限于第2组。母亲们在语用上调整了她们的言语表达，因为她们反复使用（74%）那些与孩子词汇表中相同的动词（31%）。总之，早期的多感官交流和操作场景为动词意义在正在进行的动作上提供了基础，促进了社会互动领域中的动词 - 动作配对，为当前盛行的具身认知的唯我论方法提供了一个新的维度。
