The present study compares children's and adults' ability to detect information that is conveyed through representational hand gestures. Eighteen children (M = 10 years, 1 month) and 18 college undergraduates watched videotaped stimuli of children verbally and gesturally explaining their reasoning in a problem-solving situation. A recall procedure was used to assess whether children and adults could detect information conveyed in the stimulus children's gesture and speech. Results showed that children and adults recalled information that was conveyed through representational gestures. In addition, "mismatching" gesture negatively affected the precision of speech recall for adults. However, this negative effect on speech recall was absent for children.
本研究比较了儿童和成人检测通过表征性手势传达的信息的能力。18名儿童（平均年龄10岁1个月）和18名大学生观看了儿童在解决问题情境中通过言语和手势解释其推理过程的录像刺激。采用回忆程序来评估儿童和成人是否能够检测到刺激中儿童手势和言语所传达的信息。结果表明，儿童和成人都能回忆起通过表征性手势传达的信息。此外，“不匹配”手势对成人言语回忆的准确性产生了负面影响。然而，这种对言语回忆的负面影响在儿童中并不存在。
