Positive affects vary in the degree with which they are associated with approach motivation, the drive to approach an object or a goal. High approach-motivated positive affects cause a narrowing of attention, whereas low approach-motivated positive affects causes a broadening of attention. The current study was designed to extend this work by examining whether the relationship between motivation and attentional bias was bi-directional. Specifically, the experiment investigated whether a manipulated local attentional scope would cause greater approach motivational processing than a global attentional scope as measured by neural processes as early as 100 ms. As compared to a global attentional scope, a local attentional scope caused greater neural processing associated with approach motivation as measured by the N1 to appetitive pictures.
积极情绪与趋近动机的关联程度不同,趋近动机是指趋近某个物体或目标的驱动力。高趋近动机的积极情绪会导致注意力的集中,而低趋近动机的积极情绪则会导致注意力的分散。本研究旨在通过考察动机和注意偏向之间的关系是否具有双向性来扩展这一工作。具体来说,实验通过神经过程测量,研究了在 100 毫秒内,局部注意力范围是否会比全局注意力范围引起更大的趋近动机加工。与全局注意力范围相比,局部注意力范围引起了更大的与趋近动机相关的神经加工,这可以通过 N1 对有吸引力的图片来测量。
