Re-examination of the cognitive and motivational effects of cross-categorization

我们重新研究了交叉归类的认知和动机效应。具体而言，我们创建了一个新的实验范式，考察了范畴化的自我相关性和跨范畴的认知操作对跨范畴评价的影响。我们做了三个实验，发现了以下事实。首先，交叉分类放大了组间偏见。当一个自我相关的范畴被另一个非自我相关的范畴横切时，以及当它被另一个自我相关的范畴横切时，都会发生这种放大效应。第二，对交叉范畴的认知操作降低了对交叉范畴的评价。第三，对横切范畴进行重新归类的认知操作增加了对重组后的简单范畴的评价。最后，当被试的类别包括自己的族群时，交叉类别化和再类别化的认知操作产生了相反的效果。

We re-examined the cognitive and motivational effects of cross-categorization. Specifically, we created a new experimental paradigm and investigated the effects of self-relevance of categorization and cognitive operation of cross-cutting categories on the evaluations for cross-categories. We conducted 3 experiments and found the following facts. First, cross-categorization amplified the intergroup bias. This amplification effect occurred when a self-relevant categorization was cross-cut by another non-self-relevant categorization as well as when it was cross-cut by another self-relevant categorization. Secondly, cognitive operation of cross-cutting categories decreased the evaluations for the cross-cut categories. Thirdly, cognitive operation of re-categorize the cross-cut categories increased the evaluation for the reassembled simple categories. Finally, when the categorizations included the participants' own ethnic group, the reversed effects of the cognitive operations of cross-categorization and re-categorization were obtained.
