我们评估了显着性在促使观察者在社交场景中注视眼睛方面的作用。显着性地图（Itti和科赫，2000年）计算的场景，从以前的研究。显著性对数据的解释不充分。第一个固定位置的显着性值非常低，并不大于偶然的预期。此外，眼睛区域的显著性值较低。此外，虽然显著性在预测早期扫视方面并不比晚期扫视更好，但是注视场景的社交区域（例如，眼睛）非常快（在200 ms内）。因此，视觉显著性并不能解释观察者在复杂的社会场景中选择眼睛的偏见，也不能解释一般的注视行为。相反，观察者的注视似乎主要是由他们对社会信息的默认兴趣驱动的。(C)2009爱思唯尔有限公司版权所有。
We assessed the role of saliency in driving observers to fixate the eyes in social scenes. Saliency maps (Itti & Koch, 2000) were computed for the scenes from three previous studies. Saliency provided a poor account of the data. The saliency values for the first-fixated locations were extremely low and no greater than what would be expected by chance. In addition, the saliency values for the eye regions were low. Furthermore, whereas saliency was no better at predicting early saccades than late saccades, the average latency to fixate social areas of the scene (e.g., the eyes) was very fast (within 200 ms). Thus, visual saliency does not account for observers' bias to select the eyes within complex social scenes, nor does it account for fixation behavior in general. Instead, it appears that observers' fixations are driven largely by their default interest in social information. (C) 2009 Elsevier Ltd. All rights reserved.
