Postures are known to be able to affect emotion and motivation. Much less is known about whether (affective) modulation of eye blink startle occurs following specific postures. The objective of the current study was to explore this. Participants in the present study were requested to assume three different sitting postures: with the spine flexed (slouched), neutral upright, and extended. Each posture was assumed for four minutes, and was followed by the administration of brief self-report questionnaires before proceeding to the next posture. The same series of postures and measures were repeated prior to ending the experiment. Results indicate that, relative to the other postures, the extended sitting posture was associated with an increased startle, was more unpleasant, arousing, had smaller levels of dominance, induced more discomfort, and was perceived as more difficult. The upright and flexed sitting postures differed in the level of self-reported positive affect, but not in eye blink startle amplitudes.
众所周知，姿势能够影响情绪和动机。而对于特定姿势后是否会出现眨眼惊吓的（情感）调节，人们了解得要少得多。本研究的目的就是探索这一问题。本研究要求参与者采取三种不同的坐姿：脊柱弯曲（懒散）、中立直立和伸展。每种姿势保持四分钟，然后在进入下一种姿势之前进行简短的自我报告问卷调查。在实验结束前重复相同系列的姿势和测量。结果表明，相对于其他姿势，伸展坐姿与惊吓增加、更不愉快、更具刺激性、支配水平较低、引起更多不适以及被认为更困难有关。直立坐姿和弯曲坐姿在自我报告的积极情绪水平上有所不同，但在眨眼惊吓幅度上没有差异。
