The purpose of the present continuation proposal is to obtain extended funding for one additional year for a research project supported by the Deutsche Forschungsgemeinschaft. Although the research conducted with this grant (devoted to “Sampling effects through self-truncated information search”) was successful not just in terms of empirical results and publication output, but also in terms of theoretical progress, conference activities, and fruitful collaboration with other research groups, the obtained findings have raised new challenging questions that call for continued research. In particular, the empirical results we have obtained so far on the impact of self-truncated information search and on the interplay of what we call Brunswikian and Thurstonian sampling turned out to be much stronger, and led to more refined interactions than we had expected originally. It would thus be a pity not to pursue these promising new ideas. Specifically, we intend to use the proposed continued funding for four lines of research: (1) We intend to conduct a new series of computer simulations to understand the negative correlation between amount of information and decision quality that is regularly brought about through self-truncated search. (2) One experiment will be specifically designed to test distinct ways of manipulating Thurstonian sampling effects on impression formation. (3) The aim of another experiment is to deepen our understanding of stopping rules in the context of intergroup judgment, explaining outgroup homogeneity and ingroup heterogeneity as a result of different truncation strategies. Furthermore, (4) we plan to conduct one more experiment in which we apply the notion of self-truncation effects in the meaningful applied context of advice taking.

目前的延续建议的目的是为德意志Forschungsgemeinschaft支持的研究项目获得额外的一年的扩展资金。尽管通过这项赠款进行的研究（用于“通过自我截止的信息搜索进行抽样效应”）不仅在经验结果和出版成果方面都取得了成功，而且在理论进步，会议活动以及与其他研究小组的富有成果的合作方面，所获得的发现提出了新的挑战，这些挑战提出了持续研究的挑战。尤其是，我们迄今为止对自我截断的信息搜索的影响以及我们所谓的Brunswikian和Thurstonian抽样的相互作用所获得的经验结果，结果比最初预期的要更强，并导致了更精致的相互作用。因此，可惜不追求这些诺言新想法。具体而言，我们打算使用拟议的持续资金进行四项研究：（1）我们打算进行一系列新的计算机模拟，以了解信息量与决策质量之间的负相关性，这些相关性通过自我截断的搜索定期带来。 （2）将专门设计一项实验，以测试操纵瑟斯托尼亚采样影响对印象形成的不同方法。 （3）另一个实验的目的是加深我们在群体间判断中对停止规则的理解，从而解释了由于不同的截断策略而解释了群体的同质性和内群异质性。此外，（4）我们计划进行另一个实验，在该实验中，我们将自我截断效应的概念在有意义的应用咨询背景下进行。
