The relationships between the anterior-posterior and left-right regions of the brain have been characterized as mutually inhibitory. Whereas the left hemisphere attends to right proximal hemispace and is associated with positive emotions, the right hemisphere attends to left distal hemispace and is associated with negative emotions. Because of the excitatory and inhibitory influences between the left and right frontal and posterior regions of the brain, the expression of emotion will result in an ipsilateral attentional bias. Given these functional systems, we hypothesized that positive emotions would be associated with a bias for left distal hemispace and negative emotions would be associated with a bias for right proximal hemispace. We tested these hypotheses by having 138 undergraduate students place emotionally labeled pegs on a large board. Our results indicated that the positively labeled pegs were placed in left distal hemispace and the relative placement of negatively labeled pegs was rightward and proximally. Whereas numerous research investigations have examined how attention is biased for emotional stimuli, ours is the first investigation to provide evidence that emotions can bias attentional allocation.
大脑前后区域与左右区域之间的关系被描述为相互抑制。左半球关注右侧近端半空间，并与积极情绪相关联，而右半球关注左侧远端半空间，并与消极情绪相关联。由于大脑左右额叶和后部区域之间存在兴奋和抑制性影响，情绪表达会导致同侧注意力偏向。基于这些功能系统，我们假设积极情绪与对左侧远端半空间的偏向相关，消极情绪与对右侧近端半空间的偏向相关。我们通过让138名本科生将带有情绪标签的小钉放在一个大板子上，对这些假设进行了测试。我们的结果表明，带有积极标签的小钉被放置在左侧远端半空间，而带有消极标签的小钉的相对放置位置则偏向右上方。尽管众多研究调查了注意力如何因情绪刺激而产生偏向，但我们的研究是首次提供证据表明情绪会使注意力分配产生偏向的调查。
