当专家和新手观看足球比赛录像时，我们测量了眼球运动和手动反应之间的时间关系。观察员使用操纵杆不断指示即将进球的可能性。我们测量了手动反应与受试者之间眼睛位置变异之间的相关性。为了确定滞后幅度，我们在这两个测量之间的一系列可能的延迟上重复这些相关性，并搜索最负相关系数。我们发现了大约两秒的滞后，以及专业知识对滞后幅度的影响，这表明专业知识通过将眼球运动更快地引导到场景中与任务相关的区域来发挥作用，从而在做出行为决策之前促进更长的处理持续时间。这是一种强大的新方法，用于检查多个观察者在复杂的移动图像中的眼球运动行为。
We measured the temporal relationship between eye movements and manual responses while experts and novices watch a video-taped football match. Observers used a joystick to continuously indicate the likelihood of an imminent goal. We measured correlations between manual responses and between-subjects variability in eye position. To identify the lag magnitude, we repeated these correlations over a range of possible delays between these two measures and searched for the most negative correlation coefficient. We find lags in the order of two seconds, and an effect of expertise on lag magnitude, suggesting that expertise has its effect by directing eye movements to task-relevant areas of a scene more quickly, facilitating a longer processing duration before behavioural decisions are made. This is a powerful new method for examining the eye movement behaviour of multiple observers across complex, moving images.
