Although mouse-tracking has been seen as a real-time window into different aspects of human decision-making processes, currently little is known about how the decision process unfolds in veridical and false memory retrieval. Here, we directly investigated decision-making processes by predicting participants’ performance in a mouse-tracking version of a typical Deese–Roediger–McDermott (DRM) task through distributional semantic models, a usage-based approach to meaning. Participants were required to study lists of associated words and then to perform a recognition task with the mouse. Results showed that mouse trajectories were extensively affected by the semantic similarity between the words presented in the recognition phase and the ones previously studied. In particular, the higher the semantic similarity, the larger the conflict driving the choice and the higher the irregularity in the trajectory when correctly rejecting new words (i.e., the false memory items). Conversely, on the temporal evolution of the decision, our results showed that semantic similarity affects more complex temporal measures indexing the online decision processes subserving task performance. Together, these findings demonstrate that semantic similarity can affect human behavior at the level of motor control, testifying its influence on online decision-making processes. More generally, our findings complement previous seminal theories on false memory and provide insights into the impact of the semantic memory structure on different decision-making components.

动手错误记忆:分布式语义和鼠标跟踪的联合研究

尽管鼠标跟踪已被视为人类决​​策过程不同方面的实时窗口,但目前人们对决策过程如何在真实和错误的记忆检索中展开知之甚少。在这里,我们通过分布式语义模型(一种基于使用的意义方法)预测参与者在典型 Deese–Roediger–McDermott (DRM) 任务的鼠标跟踪版本中的表现,从而直接研究决策过程。要求参与者研究相关词列表,然后用鼠标执行识别任务。结果表明,小鼠轨迹在很大程度上受到识别阶段出现的单词与之前研究的单词之间的语义相似性的影响。特别地,语义相似度越高,驱动选择的冲突越大,正确拒绝新词(即错误记忆项目)时轨迹的不规则性就越高。相反,关于决策的时间演化,我们的结果表明语义相似性影响更复杂的时间度量,这些度量为在线决策过程建立索引,从而为任务性能服务。总之,这些发现表明语义相似性可以在运动控制层面影响人类行为,证明其对在线决策过程的影响。更一般地说,我们的发现补充了先前关于错误记忆的开创性理论,并提供了对语义记忆结构对不同决策制定组件影响的见解。相反,关于决策的时间演化,我们的结果表明语义相似性影响更复杂的时间度量,这些度量为在线决策过程建立索引,从而为任务性能服务。总之,这些发现表明语义相似性可以在运动控制层面影响人类行为,证明其对在线决策过程的影响。更一般地说,我们的发现补充了先前关于错误记忆的开创性理论,并提供了对语义记忆结构对不同决策制定组件影响的见解。相反,关于决策的时间演化,我们的结果表明语义相似性影响更复杂的时间度量,这些度量为在线决策过程建立索引,从而为任务性能服务。总之,这些发现表明语义相似性可以在运动控制层面影响人类行为,证明其对在线决策过程的影响。更一般地说,我们的发现补充了先前关于错误记忆的开创性理论,并提供了对语义记忆结构对不同决策制定组件影响的见解。这些发现表明,语义相似性可以在运动控制层面影响人类行为,证明其对在线决策过程的影响。更一般地说,我们的发现补充了先前关于错误记忆的开创性理论,并提供了对语义记忆结构对不同决策制定组件影响的见解。这些发现表明,语义相似性可以在运动控制层面影响人类行为,证明其对在线决策过程的影响。更一般地说,我们的发现补充了先前关于错误记忆的开创性理论,并提供了对语义记忆结构对不同决策制定组件影响的见解。
