关于扫视控制的认知和神经要求的结论可能会因刺激呈现方法的不同而有所不同。在当前的研究中，通过评估 12 名健康年轻人的促眼跳反应和抗眼跳反应的行为差异，将其作为任务呈现方法、提示到目标间隔的长度和之前的试验类型的函数，对这个问题进行了研究。一秒的提示到目标的间隔会导致目标忽视，表现为未纠正错误和“错误”扫视反应时间的增加。对于同时条件，视觉定向速度（眼跳延迟）和抑制失败（反眼跳错误）之间也存在密切关系。有趣的是，只有同时条件才会产生任务切换成本（关于眼跳延迟和错误响应百分比）。因此，扫视任务呈现方法可以影响有关支持成功表现的认知操作的结论。
Conclusions about the cognitive and neural requirements of saccade control may differ as a result of stimulus presentation method. This issue was examined in the current study by evaluating behavioral differences in pro- and anti-saccade responses among 12 healthy young adults as a function of task presentation method, length of cue-to-target interval, and previous trial type. A one sec cue-to-target interval fostered goal neglect, indicated by an increase in uncorrected errors and reaction times for “error” saccades. There was also a strong relationship between speed of visual orienting (prosaccade latencies) and failed inhibition (antisaccade errors) for the simultaneous condition. Interestingly, only the simultaneous condition produced task switch costs (on saccade latencies and error response percentages). Saccadic task presentation method, therefore, can influence conclusions about the cognitive operations supporting successful performance.
