Abstract
The accuracy and variability of a sustained low-level force contraction (2% of maximum voluntary contraction) was measured while participants viewed unpleasant, pleasant, and neutral images during a feedback occluded force control task. Exposure to pleasant and unpleasant images led to a relative increase in force production but did not alter the variability of force production compared to conditions in which participants viewed neutral images. Findings are discussed with respect to prior work, emphasizing arousal specific changes that emerge at low target force levels.
摘要
在一项反馈遮挡力控制任务中，参与者观看不愉快、愉快和中性图像时，测量了持续低水平力收缩（最大自主收缩的 2%）的准确性和可变性。与参与者观看中性图像的条件相比，暴露于愉快和不愉快的图像会导致力产生的相对增加，但不会改变力产生的可变性。研究结果与先前的工作进行了讨论，强调了在低目标力水平下出现的特定唤醒变化。
