Abstract

Despite substantial improvements to memory precision in childhood, the neural mechanisms underlying these changes remain unclear. Here, 40 children (7–9 years; 22 females, 18 males; majority White) and 42 adults (24–35 years; 22 females, 20 males; majority White) modulated their approaches to memory formation—focusing on the specific details to encourage precision or general category to encourage imprecision. Children and adults alike formed more precise memories under the specific task, yet adults' neural states were more cohesive as a group than were children's. Moreover, children's adoption of an adult‐like neural approach explained age‐related gains in memory precision (β = 0.08). Development unfolds as children—initially varying in their memory control—eventually adopt an adult‐like approach that benefits memory precision around age 9.
编码状态的神经成熟支持儿童记忆精度的提高
尽管儿童时期的记忆精度有了实质性的提高,但这些变化背后的神经机制仍不清楚。这里有40名儿童(7-9岁;女性22人,男性18人;多数为白人)和42名成年人(24-35岁;女性22人,男性20人;大多数人(白人)调整了他们形成记忆的方法——专注于具体细节以鼓励精确,或者专注于一般类别以鼓励不精确。在特定的任务下,儿童和成人都能形成更精确的记忆,但成年人的神经状态作为一个群体比儿童更有凝聚力。此外,儿童采用类似成人的神经方法解释了与年龄相关的记忆精度增益(β = 0.08)。随着孩子们的发展——最初在记忆控制方面有所不同——最终在9岁左右采用了类似成人的方法,这有利于记忆的准确性。

期刊介绍: As the flagship journal of the Society for Research in Child Development (SRCD), Child Development has published articles, essays, reviews, and tutorials on various topics in the field of child development since 1930. Spanning many disciplines, the journal provides the latest research, not only for researchers and theoreticians, but also for child psychiatrists, clinical psychologists, psychiatric social workers, specialists in early childhood education, educational psychologists, special education teachers, and other researchers. In addition to six issues per year of Child Development, subscribers to the journal also receive a full subscription to Child Development Perspectives and Monographs of the Society for Research in Child Development.
