在一大群女性（年龄范围42-74岁）中研究了抗抢跑和正面抢跑（PS）表现。在两个变体的任务，一个“传统的”反扫视（TA）任务，其中没有视觉刺激存在于眼跳目标，和视觉引导的反扫视（VGA）任务，其中小的视觉刺激存在于可能的眼跳目标之前，必要的视觉刺激。在两个反扫视任务中，方向错误的频率是相似的。然而，反应时间（RT）在VGA任务中比在TA任务中长1.33毫秒。在所有参与者中，面部扫视和TA的平均眼跳幅度都与VGA的平均眼跳幅度相关，但彼此之间不相关。助教们的测量值随着年龄的增长而增加。扫视幅度的变异性是更高的TA比PS和VGA。扫视极角变异性低，所有三个任务。年龄降低性能与适度的任务依赖，除了增加TA hypermetria。这些结果表明，反扫视方向错误的产生并不依赖于视觉目标存在的眼跳目标，反扫视RT可以受到目标存在的影响，年龄可以增加眼跳hypermetria在没有视觉指导，视觉引导的反扫视是由不同的自愿和视觉引导眼跳机制。此外，这些结果表明，人类运动性能的理解受益于使用的参与者池具有更大的年龄范围比在大多数studies.NEW & NOTEWORTHThis研究使用了视觉引导的antisaccade（VGA）任务，以确定是否在一个大型的中年参与者池的antisaccade任务的执行控制或自愿眼跳生成的问题的结果不佳的性能。全面分析了眼跳表现的时间和空间属性与任务和年龄的关系。相关性分析用于确定自愿和视觉引导的运动机制如何共同管理VGA。
Antisaccade and prosaccade (PS) performance were studied in a large cohort of females (age range 42–74 yr). Antisaccade performance was assessed in two variants of the task, a “traditional” antisaccade (TA) task, in which no visual stimuli were present at the saccade goal, and a visually guided antisaccade (VGA) task, in which small visual stimuli were present at the possible saccade goals prior to the imperative visual stimulus. Directional error frequency was similar in the two antisaccade tasks. However, reaction time (RT) was ∼33 ms longer in the VGA task than in the TA task. Across participants, the average saccade amplitudes of prosaccades and TAs were both correlated with those of VGAs but not with each other. TAs had a hypermetria that increased with age. Saccade amplitude variability was much higher for TAs than for PSs and VGAs. Saccade polar angle variability was low for all three tasks. Age diminished performance with modest task dependence, except for an increase in TA hypermetria. These results suggest that the generation of antisaccade directional errors does not depend on visual target presence at the saccade goal, that antisaccade RT can be affected by target presence, that age can increase saccade hypermetria in the absence of visual guidance, and that visually guided antisaccades are governed by distinct voluntary and visually guided saccade mechanisms. Moreover, these results suggest that an understanding of human motor performance benefits from the use of a participant pool with a larger age range than that used in most studies.NEW & NOTEWORTHYThis study uses a visually guided antisaccade (VGA) task to determine whether poor performance in a large middle-aged participant pool on an antisaccade task results from problems with executive control or voluntary saccade generation. Spatial and temporal attributes of saccade performance as a function of task and age are analyzed comprehensively. Correlational analysis is used to determine how VGAs are governed jointly by voluntary and visually guided movement mechanisms.
