摘要: 本研究探讨图形识别学习和再认中取样的时间进程及其策略。被试为24名大学生,刺激材料为20个不规则无意义几何图形,以EyelinkII型眼动仪为主要实验设备。结果发现:显示方式和反馈条件显著影响图形再认期间的取样时间进程;图形学习时和再认时取样首视点的时间和空间方位具有显著相关,具有时空的一致性;反馈条件对取样策略调整主要体现在增加取样点数目、固定中等取样路径、增加取样点时间和减少取样辅助操作等方面;即时反馈提示显著影响再认时的取样,但是对学习时的取样影响不显著

Abstract: The time course and strategies of figure recognition is an important issue addressed by this study. Previous studies to date have focused on eye movement strategies in figure recognition. However, there are few studies that have examined how feedback effects figure perception and recognition strategies. The main goal of this research was to investigate the feedback effect on the sampling of figure recognition.
Twenty-four collage students participated this study, All participants were right handed and had normal vision. A 2 x2 mixed measures design was used in this investigation. The within-subject independent variable was the display type, with two levels (rotated and upright). The between-subject independent variable was the feedback condition with two levels (feedback and no feedback). The task was to judge whether the figures displayed in a sequence were same or not.
The results revealed that the display type and feedback condition significantly influenced participants’ figure recognition time. Additionally, the first-sampling-parts of the two irregular geometric figures displayed in sequence were significantly correlated. With feedback, the strategies of figure recognition changed on sampling number, scanning path, and sampling time.
To summarize, the feedback condition influenced the time course and strategies of figure recognition.

Key words: figure recognition, sampling, strategy, time course, feedback
