The capacity to retain the order of events is central to most of our everyday activities. Several studies aimed at investigating serial memory used the serial recall task in which participants are presented with series of items (e.g., digits) and asked to recall them in the same order they were presented. Some models suggest that the retention of serial information depends on the perceptual and motor systems (the perceptual-gestural view; Jones, Hughes, & Macken, 2006). For instance, when participants try to retain series of digits in a specific order, they would build up a plan comprising an arrangement of articulatory gestures, just as they do when they want to talk (Woodward, Macken, & Jones, 2008). The role of the motor system in retention however, has proved very difficult to test because the underlying processes are not well specified. The goal of this research program is to define the processes that are involved in retention by examining the role of the different motor systems (e.g., eye movements) in retention. In order to do this, I will use a serial recall paradigm in which participants will be asked to memorise complex natural objects. These stimuli are selected because they afford several motor actions. I will therefore manipulate various motor characteristics of the objects (e.g., how they can be seized or manipulated) and the motor systems recruited during retention. For instance, I will manipulate the similarity between the motor actions afforded by the objects and examine the effect on recall performance. The project will allow investigating what motor skills are used during retention and whether retention involves specific skills or general motor processes shared by several skills. The present research program will allow developing the perceptual-gestural view of memory and to test it against other models of memory.

保持事件顺序的能力是我们大多数日常活动的核心。几项旨在调查连续记忆的研究使用了连续回忆任务，在该任务中，参与者被呈现一系列物品（例如，数字），并被要求按照呈现的顺序回忆它们。一些模型表明，序列信息的保留取决于感知和运动系统（感知-手势观点；Jones, Hughes, & Macken, 2006）。例如，当参与者试图以特定顺序记住一系列数字时，他们会建立一个包含发音手势安排的计划，就像他们想要说话时所做的那样（Woodward, Macken, & Jones, 2008）。然而，运动系统在记忆保留中的作用已被证明是非常难以测试的，因为潜在的过程没有很好地规定。本研究计划的目标是通过检查不同运动系统（如眼球运动）在记忆保留中的作用来定义与记忆保留有关的过程。为了做到这一点，我将使用一个连续回忆范式，参与者将被要求记忆复杂的自然物体。这些刺激被选择是因为它们提供了几个运动动作。因此，我将操纵物体的各种运动特征（例如，它们如何被抓住或操纵）以及在保留期间招募的运动系统。例如，我将操纵物体所提供的运动动作之间的相似性，并检查对回忆性能的影响。该项目将允许调查在记忆过程中使用了哪些运动技能，以及记忆是否涉及特定技能或由几种技能共享的一般运动过程。目前的研究计划将允许发展记忆的感知-手势观点，并将其与其他记忆模型进行比较。
