The present study examined relationships among gaze behaviour and cardiac vagal tone using a novel stress-inducing task.
Participants' (N = 40) eye movements and heart rate variability (HRV) were measured during an unsolvable computer-based task randomly presenting feedback of "Right" and "Wrong" answers distinctly onscreen after each trial. Subgroups were created on the basis of more frequent eye movements to the right ("Correct"-Attenders; n = 23) or wrong ("Incorrect"-Attenders; n = 17) areas onscreen.
Correct-Attenders maintained HRV from baseline to the stress task. In contrast, Incorrect-Attenders spent significantly more time viewing "Wrong" feedback, exhibited a reduction in HRV during the stress condition (p < .01), and were more likely to negatively self-evaluate performance.
Results demonstrate that pervasive attention to negative feedback ("Wrong") elicits perseverative stress and negative self-evaluations among university students. This study highlights the potential for studying attentional biases and emotional distress through combined measures of gaze behaviour and cardiac vagal tone.
本研究采用一种新的应激诱导任务，考察了注视行为与心脏迷走神经张力之间的关系。
在一项不可解决的基于计算机的任务中，参与者（N=40）的眼动和心率变异性（HRV）在每次试验后屏幕上分别明显呈现“正确”和“错误”反馈时进行测量。根据参与者更多地注视屏幕右侧（“正确”注意者；n=23）或错误区域（“错误”注意者；n=17），创建了亚组。
“正确”注意者在基线到应激任务期间保持 HRV。相比之下，“错误”注意者花了更多的时间注视“错误”反馈，在应激条件下 HRV 显著降低（p<0.01），并且更有可能对表现进行负面自我评价。
研究结果表明，普遍关注负面反馈（“错误”）会引发大学生持续的应激和负面自我评价。本研究强调了通过注视行为和心脏迷走神经张力的综合测量来研究注意偏差和情绪困扰的潜力。
