异同判断加工中物体数量的作用

The Function of the Number of Objects in the Processing of Same and Different Judgment

本实验通过给被试同时呈现2或4个图形,要求被试完成异同判断任务,以考察异同判断加工中物体数量的作用。实验结果表明:(1)"同"反应随着物体数量的增多而加速,意味着"同"反应的加工机制很有可能是一种全局加工,刺激数量越大,刺激就越强,"同"判断的反应时就缩短;(2)"异"反应随着物体数量的增多而减速,支持"异"反应的加工机制很有可能是序列加工。

Through presenting two or four graphs to examinees at the same time and requiring them to finish the task of same and different judgment, the paper studied the function of the number of objects in the processing of same and different judg ment. The results showed： firstly,＂sameness＂ reaction will accelerate with the growing of the numbers of objects, which means the processing mechanism of ＂sameness＂ reaction is likely to be a global processing and the more stimulus, and the stronger the stimulation is and the time for reaction of ＂sameness＂ judgment is shorter; secondly, ＂difference＂ reaction will slow down with the growing of the number of objects and the processing mechanism of supporting ＂difference＂ reaction is likely to be a serial processing.
