Children in transition with respect to a concept, when asked to explain that concept, often convey one strategy in speech and a different one in gesture. Are both strategies activated when that child solves problems instantiating the concept? While solving a math task, discordant children (who produced different strategies in gesture and speech on a pretest) and concordant children (who produced a single strategy) were given a word recall task. All of the children solved the math task incorrectly. However, if discordant children are activating two strategies to arrive at these incorrect solutions, they should expend more effort on this task than concordant children, and consequently have less capacity left over for word-recall and perform less well on it. This prediction was confirmed, suggesting that the transitional state is characterized by dual representations, both of which are activated when attempting to explain or solve a problem.
在概念转变过程中的儿童,当被要求解释该概念时,往往在言语中传达一种策略,而在手势中传达另一种不同的策略。当那个孩子解决体现该概念的问题时,两种策略都会被激活吗?在解决一项数学任务时,不一致的儿童(在前测中手势和言语表现出不同策略)和一致的儿童(只表现出单一策略)被给予一项单词回忆任务。所有儿童都没能正确解决数学任务。然而,如果不一致的儿童为了得出这些错误答案而激活了两种策略,那么他们在这项任务上应该比一致的儿童付出更多努力,因此用于单词回忆的能力就会更少,在单词回忆任务上的表现也会更差。这一预测得到了证实,表明过渡状态的特征是双重表征,在试图解释或解决问题时,这两种表征都会被激活。
