The most frequently used measures of executive functioning are either sensitive to left frontal lobe functioning or bilateral frontal functioning. Relatively little is known about right frontal lobe contributions to executive functioning given the paucity of measures sensitive to right frontal functioning. The present investigation reports the development and initial validation of a new measure designed to be sensitive to right frontal lobe functioning, the Figure Trail Making Test (FTMT). The FTMT, the classic Trial Making Test, and the Ruff Figural Fluency Test (RFFT) were administered to 42 right-handed men. The results indicated a significant relationship between the FTMT and both the TMT and the RFFT. Performance on the FTMT was also related to high beta EEG over the right frontal lobe. Thus, the FTMT appears to be an equivalent measure of executive functioning that may be sensitive to right frontal lobe functioning. Applications for use in frontotemporal dementia, Alzheimer's disease, and other patient populations are discussed.
执行功能最常用的测量方法要么对左额叶功能敏感,要么对双侧额叶功能敏感。鉴于对右额叶功能敏感的测量方法匮乏,人们对右额叶对执行功能的贡献了解相对较少。本研究报告了一种旨在对右额叶功能敏感的新测量方法——图形连线测验(FTMT)的开发及初步验证。对42名右利手男性施测了FTMT、经典的连线测验(TMT)和鲁夫图形流畅性测验(RFFT)。结果表明,FTMT与TMT和RFFT均存在显著关系。FTMT的表现还与右额叶高β脑电图有关。因此,FTMT似乎是一种等效的执行功能测量方法,可能对右额叶功能敏感。文中还讨论了其在额颞叶痴呆、阿尔茨海默病及其他患者群体中的应用。
