Random sequence generation tests have proved to be a useful diagnostic tool for the identification of clinically relevant impairments of executive functions and for the study of cognitive functioning in healthy individuals. The most prevalent variety, random number generation, involves several limitations, however. In the original Mittenecker Pointing Test (MPT; Mittenecker, 1958), subjects were instructed to point successively and as randomly as possible at nine unlabeled circles irregularly arranged on a cardboard. With the computer program presented here, Mittenecker's classical test has been transferred to a contemporary format. The MPT can be applied using a standard PC keyboard and computes a series of sophisticated measures of deviations from randomness on the basis of information theory analysis. Because of its easy and well-controlled administration and reduced demands on memory and attention, the automatized MPT offers a wide range of application possibilities in normal but also in severely impaired clinical samples.
随机序列生成测试已被证明是一种有用的诊断工具,可用于识别执行功能的临床相关损伤,并用于研究健康个体的认知功能。然而,最常见的随机数生成方法存在多种局限性。在原始的米滕内克尔指向测试(MPT;米滕内克尔,1958)中,要求受试者依次尽可能随机地指向在硬纸板上不规则排列的九个未标记的圆圈。通过这里呈现的计算机程序,米滕内克尔的经典测试已转换为现代格式。MPT 可以使用标准 PC 键盘进行应用,并基于信息论分析计算一系列复杂的随机偏差度量。由于其易于操作且可得到良好控制,并且对记忆和注意力的要求降低,自动化的 MPT 在正常但也在严重受损的临床样本中提供了广泛的应用可能性。
