The Cognitive Estimation Test (CET) is widely used by clinicians and researchers to assess the ability to produce reasonable cognitive estimates. Although several studies have published normative data for versions of the CET, many of the items are now outdated and parallel forms of the test do not exist to allow cognitive estimation abilities to be assessed on more than one occasion. In the present study, we devised two new 9-item parallel forms of the CET. These versions were administered to 184 healthy male and female participants aged 18-79 years with 9-22 years of education. Increasing age and years of education were found to be associated with successful CET performance as well as gender, intellect, naming, arithmetic and semantic memory abilities. To validate that the parallel forms of the CET were sensitive to frontal lobe damage, both versions were administered to 24 patients with frontal lobe lesions and 48 age-, gender- and education-matched controls. The frontal patients' error scores were significantly higher than the healthy controls on both versions of the task. This study provides normative data for parallel forms of the CET for adults which are also suitable for assessing frontal lobe dysfunction on more than one occasion without practice effects.
认知估计测试（CET）被临床医生和研究人员广泛用于评估做出合理认知估计的能力。尽管已有多项研究发表了CET各版本的常模数据，但现在许多项目已经过时，且不存在该测试的平行版本，无法在多个场合评估认知估计能力。在本研究中，我们设计了两种新的包含9个项目的CET平行版本。这些版本被施测于184名年龄在18 - 79岁、受教育年限为9 - 22年的健康男性和女性参与者。研究发现，年龄增长、受教育年限增加以及性别、智力、命名、算术和语义记忆能力与CET测试的成功表现相关。为了验证CET的平行版本对额叶损伤是否敏感，两个版本都施测于24名额叶病变患者以及48名年龄、性别和教育程度相匹配的对照者。在两个版本的任务中，额叶病变患者的错误分数均显著高于健康对照者。本研究为成人CET平行版本提供了常模数据，这些版本也适用于在多个场合评估额叶功能障碍，且不存在练习效应。
