Lateral biases in spatial attention

第一部分：神经正常的人在空间注意方面表现出非常强烈和可靠的侧偏。大多数人更关注物体的左侧。同样，当被要求对大小、数量、亮度、颜色或距离做出判断时，“正常人”通常表现出向左偏倚。造成这些偏差的原因尚不清楚。这可能是因为人们倾向于从左向右扫描物体（比如阅读英语），或者是因为人们更关注左边的空间。看起来这些左倾的偏见也会影响到实验室之外的人。在现实世界中，当人们走路时与静止的物体碰撞时，他们倾向于用身体的右侧进行碰撞。这表明人们低估了右边物体的接近程度。当前提案中提出的研究是试图确定这些偏见存在的条件，以及它们是否会影响其他现实世界的活动，比如驾驶。

Part 1: Neurologically normal people exhibit very strong and reliable lateral biases in spatial attention. Most people pay more attention to the left side of the object. Similarly, when asked to make judgments of size, numerosity, brightness, colour, or distance, normals usually exhibit leftward biases. The cause of these biases is unknown. It could be because people tend to scan objects from the left to the right (like reading English), or because people pay more attention to the left side of space. It looks like these leftward biases affect people outside of the laboratory too. In the real world, when people collide with stationary objects while walking, they tend to do so with the right side of their body. This suggests that individuals underestimate the proximity of objects to the right. The research proposed in the current proposal is an attempt to determine the conditions under which these biases exist and whether they influence other real world activities, such as driving.
