Abstract

Numerous studies have indicated that both the broaden-and-build model and the motivational dimensional model emphasize the impact of emotion on spatial attention by altering the attentional scope. However, no prior research has investigated the impact of emotional valence and motivational intensity on spatial attention within the same paradigm. Furthermore, object-based attention, characterized by distinct neural mechanisms from space-based attention and also susceptible to attentional scope, represents a major pattern of selective attention. Nevertheless, it is still unclear whether and how emotional valence and motivation play a role in object-based attentional selection. Therefore, the present study aimed to explore these areas. Using a two-rectangle paradigm, Experiment 1 found that motivational intensity modulated space-based effects, whereas emotional valence modulated object-based effects. Experiment 2 used a traditional spatial cueing paradigm to further study the stability of modulating effect of motivation intensity on space-based attention, yielding results consistent with those of Experiment 1. The present study indicated that the broaden-and-build model and motivational dimensional model were not either one or the other, but both played a role in object- and space-based attention. This study provides crucial empirical evidence for theoretical complementation and integration of emotional attention.

摘要

大量研究表明,拓宽-构建模型和动机维度模型都通过改变注意力范围来强调情绪对空间注意力的影响。然而,之前没有研究在同一范式中调查情绪效价和动机强度对空间注意力的影响。此外,基于对象的注意力以不同于基于空间的注意力的神经机制为特征,并且也容易受到注意力范围的影响,是一种主要的选择性注意模式。然而,目前尚不清楚情绪效价和动机是否以及如何在基于对象的注意力选择中发挥作用。因此,本研究旨在探讨这些领域。使用两个矩形范式,实验 1 发现动机强度调节了基于空间的效应,而情绪效价调节了基于对象的效应。实验 2 使用传统的空间提示范式进一步研究了动机强度对基于空间的注意力的调节作用的稳定性,结果与实验 1 的结果一致。本研究表明,拓宽-构建模型和动机维度模型不是一个或另一个,而是两者都在基于对象和基于空间的注意力中发挥作用。本研究为情绪注意力的理论补充和整合提供了重要的经验证据。
