Though the frequency of gesture use by infants has been related to the development of different language abilities in the initial stages of language acquisition, less is known about whether this frequency (or "gesture rate") continues to correlate with language measures in later stages of language acquisition, or whether the relation to language skills also depends on the accuracy with which such gestures are produced (or reproduced). This study sets out to explore whether preschoolers' narrative abilities are related to these two variables, namely, gesture rate and gesture accuracy.
A total of 31 typically developing 3- to 4-year-old children participated in a multimodal imitation task, a context-based gesture elicitation task, and a narrative retelling task.
Results showed that there was a significant positive correlation between the children's narrative scores and their gesture accuracy scores, whereas higher rates of gesture use did not correlate with higher levels of narrative skill. Further multimodal regression analysis confirmed that gesture accuracy was a positive predictor of narrative performance, and moreover, showed that gesture rate was a negative predictor.
The fact that both gesture accuracy and gesture rate are strongly and differently linked to oral language abilities supports the claim that language and gesture are highly complex systems, and that complementary measures of gesture performance can help us assess with greater granularity the relationship between gesture and language development. These findings highlight the need to use gesture during clinical assessments as an informative indicator of language development and suggest that future research should further investigate the value of multimodal programs in the treatment of language and communication disorders.
尽管婴儿使用手势的频率与语言习得初始阶段不同语言能力的发展有关,但对于这种频率(或“手势率”)是否与语言习得后期的语言测量继续相关,或者这种与语言技能的关系是否也取决于这些手势的准确性(或再现),人们知之甚少。本研究旨在探讨学龄前儿童的叙事能力是否与这两个变量(即手势率和手势准确性)相关。
共有 31 名发育正常的 3 至 4 岁儿童参加了多模态模仿任务、基于语境的手势引出任务和叙事复述任务。
结果表明,儿童的叙事得分与他们的手势准确性得分呈显著正相关,而较高的手势使用率与较高的叙事技能水平无关。进一步的多模态回归分析证实,手势准确性是叙事表现的积极预测因素,而且,表明手势率是一个消极的预测因素。
手势准确性和手势率都与口语语言能力强烈而不同地相关,这一事实支持了语言和手势是高度复杂的系统的观点,并且补充的手势表现措施可以帮助我们更细致地评估手势与语言发展之间的关系。这些发现强调了在临床评估中使用手势作为语言发展的信息指标的必要性,并表明未来的研究应进一步调查多模态方案在语言和交流障碍治疗中的价值。
