Previous studies have shown that ﬂanking distracters inﬂuence line bisection. In the present study, we examined if reaching the ﬂanker after bisecting the line resulted in a variation of ﬂanker interference on line bisection. Right- and left-handed participants were asked to bisect a horizontal line ﬂanked by a dot (bisection task, B-task) or to bisect the line and then to reach the dot (bisection plus reaching task, BR-task). The dot was placed laterally to, and above or below, the line edge. The results showed that in both tasks the subjective midpoint was shifted away from the position of the dot. However, this effect was greater in the BR-task than in the B-task. We suggest that the requirement to perform an action to the ﬂanker in the BR-task induced participants to pay more attention to the dot, enhancing its salience and distorting effects on line bisection.
