In the study, 33 participants viewed photographs from either a potential homebuyer's or a burglar's perspective, or in preparation for a memory test, while their eye movements were recorded. A free recall and a picture recognition task were performed after viewing. The results showed that perspective had rapid effects, in that the second fixation after the scene onset was more likely to land on perspective-relevant than on perspective-irrelevant areas within the scene. Perspective-relevant areas also attracted longer total fixation time, more visits, and longer first-pass dwell times than did perspective-irrelevant areas. As for the effects of visual saliency, the first fixation was more likely to land on a salient than on a nonsalient area; salient areas also attracted more visits and longer total fixation time than did nonsalient areas. Recall and recognition performance reflected the eye fixation results: Both were overall higher for perspective-relevant than for perspective-irrelevant scene objects. The relatively low error rates in the recognition task suggest that participants had gained an accurate memory for scene objects. The findings suggest that the role of bottom-up versus top-down factors varies as a function of viewing task and the time-course of scene processing.
在这项研究中,33名参与者从潜在购房者或窃贼的视角观看照片,或者为进行记忆测试做准备,同时记录他们的眼球运动。观看照片后进行了自由回忆和图片识别任务。结果表明,视角具有快速影响,即场景开始后的第二次注视更有可能落在场景中与视角相关而非与视角无关的区域。与视角无关的区域相比,与视角相关的区域也吸引了更长的总注视时间、更多的注视次数和更长的首次通过停留时间。至于视觉显著性的影响,首次注视更有可能落在显著区域而非非显著区域;显著区域也比非显著区域吸引了更多的注视次数和更长的总注视时间。回忆和识别表现反映了眼球注视结果:与视角相关的场景对象在总体上比与视角无关的场景对象表现更高。识别任务中相对较低的错误率表明参与者对场景对象有准确的记忆。研究结果表明,自下而上和自上而下因素的作用会根据观看任务和场景处理的时间进程而有所不同。
