摘要: 探讨不规则几何图形识别中取样的眼动特征。被试为12名大学生,刺激材料为20个不规则几何图形,采用EyelinkII型眼动仪。结果发现,随作业难度加大,被试在认知加工中的有效取样时间比显著下降。在不良视觉条件下,图形信息的取样点数量显著减少,眼动扫视路径显著增长。在识别旋转图形时,有效取样时间下降,取样点数量增加,眼动扫视路径增长。图形信息的显示条件与显示方式的交互作用对图形识别的反应时、取样点的数量和眼动扫视路径长度的影响显著。

Abstract: A eye movements study on sampling traits for irregular geometric figure recognition was conducted. Ss were 12 university students. The stimuli were 20 irregular geometric figures. The equipment was EyelinkII tracker in the experiment. It was found that, with the task difficulty increasing, the ratio of effective sampling time descended significantly. In poor display condition, the number of fixations reduced significantly and the sacnpaths become significant longer than in good display condition. The interaction between display condition and display style had a significant effect on RT,the number of fixations and the length of scanpaths.

Key words: figures recognition, sampling, eye movements
