Lateral biases in spatial attention

第一部分：神经系统正常的人在空间注意力方面表现出非常强烈和可靠的横向偏差。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，法线通常会表现出明显的偏差。这些偏差的原因尚不清楚。这可能是因为人们倾向于从左到右扫描物体（比如阅读英语），或者因为人们更关注空间的左侧。看起来这些偏见也影响了实验室以外的人。在真实的世界中，当人们在行走时与静止的物体相撞时，他们往往会用身体的右侧这样做。这表明人们低估了物体向右的接近程度。 目前提案中提出的研究是试图确定这些偏见存在的条件，以及它们是否影响其他真实的世界活动，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.
