中文摘要：

给22名被试呈现若干组在外形与纹路上变化的电池图片，要求指出何种类型的电池有电。结果发现，被试会快速觉察电池的共享特征并概括出一般性的结论。如若电池间无共享特征，被试则需较长时间才给出“无法概括”的反应。共享纹路时，被试在“共享-无干扰”条件下的反应明显快于“共享-有干扰”条件下的反应，体现出假设形成与验证的过程。共享特征为外形的反应时短于共享特征为纹路的反应时，这说明被试在任务中采用的是整体优先的加工策略。

英文摘要：

Twenty-two subjects were presented with figures of battery sets consisting of four batteries different in shape and stripes. The subjects were asked to indicate what kind of batteries could produce electricity. The results indicated that if the charged batteries shared some features, the subjects could detect this shared feature quickly and make a general conclusion. On the contrary, if the charged batteries did not share a feature, the subjects would respond slowly. If the shared feature was stripe, the subjects would respond more quickly in the＇shared-but-interference-free condition than the shared-but-with-interference condition, and manifested the process of hypothesis forming and testing. The reaction time was longer if the shared feature was shape. This suggested that subjects often applied a global precedence strategy.
