An increasing number of studies have provided evidence in favor of the idea that verbal memory and language production rely on the same processes. For instance, some researchers have shown that recall performance is modulated by the linguistic properties of items and others have shown that errors produced in serial recall mimic the errors observed during language production. In line with this idea, a number of researchers have suggested that verbal memory plays a key role during language learning. Although most researchers acknowledge a role for language production in verbal memory, it is unclear what is its role and to what extent it contributes to verbal immediate retention and learning. For instance, there is a debate about whether or not the language production architecture is sufficient to support verbal retention, or whether a specialised dedicated memory store is necessary to account for retention. The long-term objective of this program is to further this line of research and to investigate the role of language production in verbal memory in order to reconcile memory models and models of language production. We will use an experimental design combining a memory task and a task requiring language production. In the general procedure, participants are first required to retain a series of verbal items presented auditorily through loudspeakers. After presentation of the list, they are presented visually with a list of verbal items that they have to articulate out loud, followed by a recall of the initial list. The proposed research program is structured in three phases. In the first part of this program, we will manipulate the similarity between the list in memory and the list to articulate. If language production and retention rely on the same processes, such overlap should impair articulation as well as recall performance. In the second part of this program, we will investigate whether the language production architecture is sufficient to account for memory performance or whether other processes, such as speech perception, must be called upon for retention. In the third part, the role of language production in verbal learning will be investigated by repeating either the list to retain or the list to articulate at regular intervals throughout the experiment. This program of research will investigate the mechanisms supporting verbal memory and learning and contribute to bridging the gap between two fields of research that have evolved mostly in parallel, but that bear striking similarities. We will do so by using a new innovative experimental method that will allow assessing the mutual influence between the production of language and verbal memory. The knowledge gained from this research program will have critical impact on our understanding of normal cognitive functioning and have implications for understanding language and verbal memory impairments.

越来越多的研究提供了支持非文字记忆和语言产生依赖于相同过程的证据。例如，一些研究人员已经表明，召回性能是由项目的语言属性调制和其他人已经表明，在串行回忆中产生的错误模仿在语言生产过程中观察到的错误。根据这一观点，许多研究人员认为，言语记忆在语言学习中起着关键作用。虽然大多数研究者承认语言产生在言语记忆中的作用，但它的作用是什么以及在多大程度上有助于言语即时记忆和学习还不清楚。例如，关于语言产生架构是否足以支持口头保留，或者是否需要专门的专用记忆存储来解释保留，存在争议。该计划的长期目标是进一步研究这一领域，并研究语言产生在言语记忆中的作用，以协调记忆模型和语言产生模型。我们将使用一个实验设计，结合记忆任务和需要语言生产的任务。在一般的程序中，参与者首先需要记住一系列通过扬声器播放的口头项目。在呈现列表之后，他们被视觉地呈现一个他们必须大声表达的口头项目列表，然后回忆最初的列表。拟议的研究计划分为三个阶段。在这个程序的第一部分，我们将操纵内存中的列表和要表达的列表之间的相似性。如果语言的产生和记忆依赖于相同的过程，那么这种重叠会损害发音和回忆的表现。在本课程的第二部分，我们将研究语言产生架构是否足以解释记忆表现，或者是否必须调用其他过程（如言语感知）来保持记忆。在第三部分中，语言产出在言语学习中的作用将通过在整个实验过程中定期重复要保留的列表或要表达的列表来研究。该研究计划将调查支持非文字记忆和学习的机制，并有助于弥合两个研究领域之间的差距，这两个研究领域主要是平行发展的，但具有惊人的相似之处。我们将使用一种新的创新实验方法来评估语言和非文字记忆之间的相互影响。从这项研究计划中获得的知识将对我们理解正常的认知功能产生关键影响，并对理解语言和言语记忆障碍产生影响。
