Observers typically show systematic errors in spatial perception when asked to bisect a line. We examined whether misbisection relates to the extent by which the midpoint is scrutinized explicitly. Participants were required to position a soccer goalkeeper at the exact midpoint of the goal line, drawing explicit attention to the midpoint of the line. Subsequently, they carried out a penalty kick to score a goal, without eliciting explicit attention for the centre of the goal for choosing the side to which to kick the ball. We found that participants positioned the goalkeeper to the right of the centre, confirming the previously reported rightward bias for line bisections in extra-personal space. Although participants (erroneously) believed that the goalkeeper stood in the centre, they kicked the ball to the bigger side of the goal more often. These findings indicate that asymmetries in spatial perception are more evident with explicit than implicit attention.
当被要求平分一条线时，观察者在空间感知上通常会表现出系统性错误。我们研究了平分错误是否与明确审视中点的程度有关。参与者被要求将一名足球守门员放置在球门线的精确中点处，从而明确将注意力集中在线条的中点上。随后，他们进行点球射门，在选择向球门哪一侧踢球时，无需明确关注球门中心。我们发现参与者将守门员放置在中心右侧，证实了先前报道的在个人空间外线条平分时的向右偏差。尽管参与者（错误地）认为守门员站在中心位置，但他们更频繁地将球踢向球门较大的一侧。这些发现表明，空间感知中的不对称在明确关注而非隐式关注时更为明显。
