记忆灵活性是人类记忆系统的一个标志。正如感知上不同的物体之间的泛化所索引的那样，记忆的灵活性在婴儿期逐渐发展。最近的一项研究发现，在18个月大的时候，双语在记忆概括方面具有优势[Brito and巴尔[2012] Developmental Science，15，812-816]，本研究考察了这种优势何时首次出现。在目前的研究中，双语6个月大的婴儿比单语婴儿更有可能概括为两个特征（形状和颜色）不同于单语6个月大婴儿的木偶。当挑战一个不太复杂的变化，两个木偶，只有一个特征颜色不同，单语6个月大的孩子也能够概括。这些发现表明双语婴儿记忆概括的早期出现差异，并对我们理解早期环境变化如何塑造记忆发展的轨迹具有重要意义。(C)2013 Wiley Periodicals，Inc.
Memory flexibility is a hallmark of the human memory system. As indexed by generalization between perceptually dissimilar objects, memory flexibility develops gradually during infancy. A recent study has found a bilingual advantage in memory generalization at 18 months of age [Brito and Barr [2012] Developmental Science, 15, 812-816], and the present study examines when this advantage may first emerge. In the current study, bilingual 6-month-olds were more likely than monolinguals to generalize to a puppet that differed in two features (shape and color) than monolingual 6-month-olds. When challenged with a less complex change, two puppets that differed only in one feature-color, monolingual 6-month-olds were also able to generalize. These findings demonstrate early emerging differences in memory generalization in bilingual infants, and have important implications for our understanding of how early environmental variations shape the trajectory of memory development.
