Following biological and comparative perspectives, it was posited that acute stressors would activate more primitive modes of action control favoring gross motor actions (e.g., fight or flight) over behavioral precision. Influences of this type should result in more rapid changes in movement velocity subsequent to emotionally upsetting stimulation. In investigating processes of this type, participants in three experiments (total N = 457) were asked to track a moving visual target as smoothly as possible. The introduction of brief, aversive noise blasts was found to destabilize such efforts. In particular, time-locked analyses revealed the presence of an emotion-related increase in tremor that began quickly and persisted for nearly 2 s. In addition, the persistence component was elevated in the context of higher levels of neuroticism (Experiment 2) and emotional reactivity (Experiment 3). The results speak to questions about the emotion-action interface using a method suited to affective chronometry. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

与情绪有关的运动性震颤变化：幅度，时程以及与情绪气质的联系。

根据生物学和比较的观点，假定急性应激源将激活更原始的动作控制模式，从而有利于总运动动作（例如战斗或逃跑），而不是行为精确度。这种类型的影响应导致情绪激动后的运动速度更快变化。在调查这种类型的过程时，要求三个实验的参与者（总N = 457）尽可能平稳地跟踪运动的视觉目标。人们发现，引入短暂的，厌恶的噪音爆炸会破坏这种努力的稳定性。尤其是，时间锁定分析显示，与情感有关的震颤增加迅速开始并持续了近2 s。此外，在较高的神经质水平（实验2）和情绪反应（实验3）的情况下，持久性成分增加。该结果使用适合情感计时的方法来回答有关情感-动作界面的问题。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
