Abstract:
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.
