The inter-relationships between visual lobe dimensions, search times and eye movement parameters were investigated for a competition search task with 18 subjects. The subjects had previously participated in a visual lobe measurement and two search performance experiments using the same set of stimulus material. Using an Eye Mark Recorder, the average search times of subjects were found to be comparatively longer than for previous search tasks not using the recorder, and relative search performance ranks of the subjects were altered. The method of stimulus presentation and the search area were different in this experiment, so we cannot be certain as to which factor or factors caused the lengthening of search times and changes in ranking. All subjects achieved a 100% hit rate with no mis-classification of targets. A very high correlation coefficient was obtained for cumulative detection percentage and pooled search times when fitted to a random search model. Average search times were found to be significantly correlated with fixation durations as well as with the number of fixations. Contrary to expectation, none of the visual lobe dimensions was found to correlate significantly with average search times nor with eye movement parameters.
针对一项有18名受试者参与的竞争搜索任务，研究了视叶尺寸、搜索时间和眼动参数之间的相互关系。这些受试者之前参与了一项视叶测量以及两项使用同一组刺激材料的搜索性能实验。使用眼动记录仪发现，受试者的平均搜索时间相较于之前未使用该记录仪的搜索任务要长得多，并且受试者的相对搜索性能排名发生了变化。本实验中刺激呈现方法和搜索区域有所不同，所以我们无法确定是哪个或哪些因素导致了搜索时间延长和排名变化。所有受试者的命中率均达到100%，且没有对目标进行错误分类。当拟合到随机搜索模型时，累积检测百分比和总搜索时间获得了非常高的相关系数。发现平均搜索时间与注视持续时间以及注视次数显著相关。与预期相反，未发现任何视叶尺寸与平均搜索时间或眼动参数显著相关。
