The present study investigated the impact of the dominant hand on performance in two paper-and-pencil tests of visual selective attention (d2-R; FAIR-2). We hypothesized that preview benefits (i.e., preprocessing of stimuli located to the right of the currently fixated item) could improve test performance of left-handers as compared to right-handers because using the right hand could prevent preview benefits simply by covering subsequent stimuli. A group of left-handed students (n = 86) and a group of right-handed students (n = 90) completed both the test d2-R and the test FAIR-2 with their dominant (writing) hand. Results showed that left-handed participants outperformed right-handers in both tests. Hence, when the results of left-handers are to be compared to right-handers or to normative data (which are dominated by right-handers), the impact of preview benefits on left-hander performance should be taken into account.
本研究调查了惯用手对两种纸笔视觉选择性注意测试（d2-R；FAIR-2）表现的影响。我们假设，预览优势（即对当前注视项目右侧的刺激进行预处理）可以提高左撇子的测试表现，而不是右撇子，因为使用右手可能会通过遮挡后续刺激来简单地阻止预览优势。一组左撇子学生（n=86）和一组右撇子学生（n=90）用他们的惯用手（写字手）完成了 d2-R 和 FAIR-2 测试。结果表明，左撇子参与者在两个测试中的表现都优于右撇子。因此，当将左撇子的结果与右撇子或规范数据（主要由右撇子组成）进行比较时，应考虑预览优势对左撇子表现的影响。
