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.

该提案的目的是为Orschungsgemeinschaft支持的Aresearch项目额外获得一年。袭击的质疑是持续研究的质疑追求这些承诺的新想法。搜索（2）一种经验，以测试对RSTONIAN对改善的效果的不同方式，以解释群体均值和群体异质性作为Aruncaties策略。我们在应用建议采取的范围的上下文中应用了自我截断效应概念的更多实验。
