The development of prospective memory in early childhood: Contributions of retrospective memory and executive control processes

这个研究项目考察了儿童如何发展记忆能力，以实现他们的意图，被称为前瞻性记忆。这是一种重要的认知能力，使儿童能够独立于父母和照顾者。儿童日常生活中典型的前瞻性记忆任务的例子包括记住将家庭作业还给老师或记住在骑自行车之前戴自行车头盔。有趣的是，孩子们经常忘记执行他们的意图，尽管他们能够记住并报告他们应该做什么。这种能力对儿童发展的许多领域都有重要影响，包括他们的学术和社会功能以及他们的安全和福祉。一个典型的实验室前瞻性记忆任务包括：（1）儿童被分配一个前瞻性的意图，（2）引入一个延迟间隔，儿童在其中完成一个干扰活动，（3）一个正在进行的任务，遵循延迟间隔，（4）几个线索，出现在正在进行的任务，信号，儿童应该完成的前瞻性意图。在研究结束时，孩子们被要求确认他们记住了任务指令，以消除孩子们只是忘记了他们应该做什么的可能性。本研究旨在探讨回溯记忆（回忆前瞻意图的内容）和执行过程（涉及线索的发现和意图的实现）对幼儿期前瞻记忆表现的影响。三个项目将研究幼儿期前瞻性记忆和回顾性记忆之间的关系，排除前瞻性记忆失败是由于回顾性记忆短暂失误的可能性，并研究可能减少执行要求以促进成功的前瞻性记忆的因素。综上所述，本研究将有助于更好地理解执行过程（如线索监测）是否有助于前瞻记忆的发展，以及回顾记忆对前瞻记忆发展的相对贡献。这项研究将测试前瞻性记忆的发展模型（Mahy，Moses和Kliegel，2014），该模型声称，尽管在儿童表现出成功的前瞻性记忆之前，简单意图的回顾性记忆必须到位，但执行过程，如对前瞻性记忆线索的监测，会推动儿童时期前瞻性记忆的发展。研究结果将确定儿童的前瞻性记忆成功的条件和失败的条件。更广泛地说，它将有助于我们理解儿童的记忆发展，特别是执行未来意图的记忆。

This program of research examines how children develop the ability to remember to carry out their intentions, known as prospective memory. This is a critical cognitive ability that allows children to function independently from their parents and caregivers. Examples of prospective memory tasks typical in children's everyday life include remembering to return a homework assignment to a teacher or remembering to wear a bicycle helmet before taking a bike ride. Interestingly, children often forget to carry out their intentions despite being able to remember and report what it was they were supposed to do. This ability has important implications for many areas of children's development including their academic and social functioning as well as their safety and well-being.***A typical laboratory prospective memory task involves: (1) children being assigned a prospective intention, (2) the introduction of a delay interval in which children complete a distractor activity, (3) an ongoing task that follows the delay interval, and (4) several cues that appear in the ongoing task that signal that the child should complete the prospective intention. At the end of the study, children are asked to confirm that they remember the task instructions in order to eliminate the possibility that children simply forgot what they were supposed to do.******The current research will examine the contributions of retrospective memory (remembering the content of the prospective intention) and executive processes (involved in detecting the cue and carrying out the intention) to prospective memory performance during early childhood. Three projects will examine the relation between prospective memory and retrospective memory across early childhood, rule out the possibility that prospective memory failures are due to momentary lapses in retrospective memory, and examine factors that might reduce executive demands to promote successful prospective memory. Taken together, this research will contribute to a better understanding of whether executive processes such as cue monitoring contribute to the development of prospective memory and what the relative contribution of retrospective memory is to prospective memory development.******This research will test a developmental model of prospective memory (Mahy, Moses, & Kliegel, 2014) that asserts that although retrospective memory for simple intentions must be in place before a children demonstrate successful prospective memory, executive processes such as monitoring for the prospective memory cue drive the development of prospective memory during childhood. The findings will establish the conditions under which children's prospective memory is successful and conditions under which it fails. More broadly, it will contribute to our understanding of children's memory development, especially memory for carrying out future intentions.**
