Previous research has only examined perceptual deficits that are hypothesized in a model of stress and injury under laboratory-induced stress conditions. The generalizability of findings from such induced-stress conditions is limited beyond the laboratory. The current research examined the influence of life-event stress and hardiness on peripheral narrowing in a real-life stress situation. Athletes completed life-stress and hardiness questionnaires, along with measures of state anxiety and peripheral vision. The stress condition was obtained by assessing the athletes within 2 hours of a competition. The real-life stress condition had a larger effect on state anxiety and peripheral narrowing than the laboratory-induced situations used in previous research, with effect sizes twice and three times as large as those reported in the literature. All athletes experienced significant reductions in peripheral vision prior to competition, regardless of life-event stress or hardiness levels.
以往的研究仅考察了在实验室诱导的应激条件下，应激与损伤模型中假设的感知缺陷。此类诱导应激条件下的研究结果的普遍性在实验室之外是有限的。当前的研究考察了生活事件应激和心理韧性对现实生活应激情境中外周视野变窄的影响。运动员完成了生活应激和心理韧性问卷，以及状态焦虑和外周视野测量。应激条件是通过在比赛前2小时内评估运动员获得的。与以往研究中使用的实验室诱导情境相比，现实生活应激条件对状态焦虑和外周视野变窄的影响更大，效应大小是文献报道的两倍和三倍。所有运动员在比赛前外周视野都有显著降低，无论生活事件应激或心理韧性水平如何。
