The cone of direct gaze refers to the range of gaze deviations an observer accepts as looking directly at them. Previous experiments have calculated the width of the cone of direct gaze using the gaze deviations actually presented to the observer, however, there is considerable evidence that observers actually perceive gaze to be systematically more deviated than actually presented. Here, we examine the width of the cone of direct gaze in units of perceived gaze deviation. In doing so, we are able to disambiguate differences in width both within and between observers that are due to differences in their perception of gaze and due to differences in what observers consider to be looking at them. We suggest that this line of inquiry can offer further insight into the perception of gaze direction, and how this perception may differ in clinical populations.
直接注视锥指的是观察者认为他人直接看向自己时所能接受的注视偏差范围。以往的实验通过实际呈现给观察者的注视偏差来计算直接注视锥的宽度,然而,有大量证据表明,观察者实际感知到的注视偏差比实际呈现的要系统地更大。在此,我们以感知到的注视偏差为单位来研究直接注视锥的宽度。这样做,我们能够区分观察者内部和观察者之间由于他们对注视的感知差异以及由于观察者认为他人看向自己的标准差异而导致的宽度差异。我们认为,这条研究思路可以为注视方向的感知以及这种感知在临床人群中可能存在的差异提供进一步的见解。
