The purpose of this paper is to systematically examine the research literature on the decision of expert interviewers within the theoretical framework of the Hierarchy of Expert Performance (HEP). After providing an overview of the HEP framework, existing research in the investigative interviewing at each of the eight levels of the HEP framework is reviewed. The results identify areas of strength in reliability between experts’ observations (Level 2) and of weakness in reliability between experts’ conclusions (Level 6). Biases in investigative interview experts’ decision making is also revealed at biasability between expert conclusions (Level 8). Moreover, no published data are available in reliability within experts at the level of observations (Level 1) or conclusions (Level 5), biasability within or between expert observations (Level 3 and 4) and biasability within expert conclusions (Level 7). The findings highlight areas where future research and practical endeavour are much needed for the investigative interview.

本文的目的是在专家绩效等级（HEP）的理论框架内系统地研究关于专家访谈员决策的研究文献。在概述了 HEP 框架之后，将对 HEP 框架八个级别中每个级别的调查性访谈中的现有研究进行审查。结果确定了专家观察之间可靠性强的领域（2 级）和专家结论之间可靠性的弱点（6 级）。调查访谈专家决策中的偏差也体现在专家结论之间的偏差上（级别 8）。此外，在专家级别上，没有可靠的已发表数据。观察（级别 1）或结论（级别 5）、专家观察内部或之间的偏差（级别 3 和 4）以及专家结论内的偏差（级别 7）。调查结果突出了调查访谈非常需要未来研究和实际努力的领域。
