The major aim of the proposed research is the advancement of psychological assessment by researching the item-position effect that is biasing measurement in the area of ability testing. For achieving this aim the research proposal suggests the construction of a methodology for the reliable detection and identification of the item-position effect in ability data, the optimization of the representation of the item-position effect in considering disturbances due to ceiling and similarity effects, the extension of the available method for data obtained in non-speeded testing to data obtained in speeded testing. Furthermore, the proposed research shall contribute to the further clarification of the sources of the item-position effect. Accordingly it is to be clarified whether the item-position effect is due to learning and whether there is an interaction with the difficulty-guided arrangement of items. A major part of the research work has to be conducted by means of simulated data. Simulated data enable the control over the general characteristics of data and, therefore, are especially well suited for finding out about the detectability of the item-position effect and about the specificities of the arrangement of items. The investigation of the impact of speeded testing on the item-position effect requires empirical data and also the investigation of the sources of the item-position effect. The investigation of the sources concentrates on the learning hypothesis. Therefore, the data collection must include the application of measures of learning besides ability measures. In the end there should be a revised method that enables the control of the item-position effect and eventually its exploitation as another source of valuable information.

本研究的主要目的是通过对能力测验中偏置测量的项目位置效应的研究，推动心理测评的发展。为了实现这一目标的研究建议，建议建设一个可靠的检测和识别的能力数据中的项目位置效应的方法，优化的项目位置效应的表示，考虑干扰由于天花板和相似性的影响，扩展的可用方法获得的数据在非加速测试中获得的数据在加速测试。此外，本文的研究将有助于进一步阐明项目位置效应的来源。因此，它是要澄清的项目位置效应是否是由于学习和是否有一个相互作用的项目的困难导向的安排。研究工作的主要部分必须通过模拟数据进行。模拟数据能够控制数据的一般特性，因此，特别适合于发现项目位置效应的可检测性和项目排列的特殊性。研究快速测试对项目位置效应的影响需要实证数据，也需要研究项目位置效应的来源。对来源的考察主要集中在学习假设上。因此，数据收集除了能力测量外，还必须包括学习测量的应用。最后，应该有一个修正的方法，使项目位置效应的控制，并最终开发其作为另一个有价值的信息来源。
