以复合汉字为材料,通过两个实验探讨在心理旋转加工中是否存在整体/局部优先效应。实验一检验视知觉中的整体优先效应,实验二考察心理旋转加工中是否存在整体优先效应。结果表明:延长刺激呈现时间直至被试做出反应,在正镜像判断的纯视觉任务中不存在视觉整体优先效应;在心理旋转任务中,大汉字(整体)旋转条件反应时与小汉字(局部)旋转反应时差异不显著。这些结果说明复合汉字刺激心理旋转加工中不存在整体优先效应。
Mental rotation was one typical transformation of mental images, which was higher connective processes and reported to be functional equivalence with visual perception. Previous studies had indicated that global precedence was found in visual perception and mental rotation. Perceptual global precedence refers to a priority in perceptual processing for the global features of a form or object, the most commonly used experimental material in this field is compound letters. However, it was still unclear that whether global precedence could exist in other materials, such as Chinese characters. In the present research, to explore whether there was an effect of global precedence on mental rotation with compound Chinese characters stimuli （ larger characters were constructed from smaller ones, e. g. , a large ＂ 上＂ made up of lots of small ＂下＂）.
In Experiment 1, 32 college students took part in a task to judge whether the large character or small character of the compound stimulus was in its regular format or left-right mirror, 2（ task： identification of normal image/mirror-reversed image for large or small characters）X 2{stimuli： congruence or incongruenee of large-small characters） was designed to eliminate perceptual global precedence though prolonging the duration of target stimuli. Experiment 2 investigated the global precedence on mental rotation with a 4 （rotation degree： 0, 60, 120,180） × 2 （rotation pattern： rotation of large characters or small characters） × 2（stimuli： congruence or incongruence of rotation angles of large-small characters） within-subject factorial design for another 32 college students, the tasks was same as in Experiment 1. Results showed that prolonging targets＇ duration until the participants responded, perceptual global precedence could be eliminated in judging regular format and mirroring of visual perception. When mental rotation was add to the task, there was no significant difference between RTs of identification of large and small characters. Based on these result, the conclusion was that global precedence didn＇t exist in mental rotation when adopted compound Chinese characters as experimental material. And the research results from visual perception are the same.
