本研究旨在验证一个计算机化的心理旋转任务开发用于功能磁共振成像（fMRI）研究。83名女性和74名男性完成了计算机任务，两个心理旋转的纸和纸测试，并报告了他们的数学，英语和历史的高中成绩。计算机化的任务包括呈现成对的三维刺激，这些刺激的方向相差0、40、80、120或160度。结果表明，在三个主要任务中，男性的性别差异显着，虽然在计算机化任务中，性别与旋转角度相互作用。并行有效性的证据获得的形式显着的相关性表现在任务的心理旋转（纸和铅笔测试和数学成绩），而判别有效性证明了缺乏相关性与任务被认为无关的心理旋转（英语和历史成绩）。这些发现支持使用我们的计算机化心理旋转任务作为一个有效的措施，心理旋转能力的功能磁共振成像研究。本研究由国家卫生研究所资助（J.

The present study aimed at validating a computerized mental rotation task developed for use in functional Magnetic Resonance Imaging (fMRI) studies. Eighty-three females and 74 males completed the computerized task, two pencil-and-paper tests of mental rotation, and reported their high school grades in mathematics, English, and history. The computerized task involved the presentation of pairs of three-dimensional stimuli that differed in orientation by 0, 40, 80, 120, or 160 degrees. Results showed significant gender differences in favor of males in the three main tasks, although gender interacted with angle of rotation in the computerized task. Evidence for concurrent validity was obtained in the form of significant correlations between performance on tasks relevant to mental rotation (paper and pencil tests and mathematics grades), whereas discriminant validity was demonstrated by a lack of correlation with tasks deemed irrelevant to mental rotation (English and history grades). These findings support the use of our computerized mental rotation task as a valid measure of mental rotation abilities in fMRI studies. This study was funded by a National Institute of Health grant (J. Imperato-McGinley, Principal Investigator). The authors are thankful to Mariana Soraggi for her assistance with data collection and scoring. We are also indebted to Michael Peters for providing the three-dimensional drawing used in the computerized task.
