Controversy surrounds the relationship between emotion and attention in brain and behavior. Two recent studies acquired millisecond-level data to investigate the timing of emotion and attention effects in the amygdala (Luo et al., 2010; Pourtois et al., 2010). Both studies argued that the effects of emotional content temporally precede those of attention and that prior discrepancies in the literature may stem from the temporal characteristics of the functional MRI (fMRI) signal. Although both studies provide important insights about the temporal unfolding of affective responses in the brain, several issues are discussed here that qualify their results. Accordingly, it may not be yet time to accept the conclusion that "automaticity is a matter of timing". Indeed, emotion and attention may be more closely linked than suggested in the two studies discussed here.
大脑与行为中情绪和注意力之间的关系存在争议。最近的两项研究获取了毫秒级数据,以研究杏仁核中情绪和注意力效应的时间安排(Luo等人,2010年;Pourtois等人,2010年)。两项研究均认为,情绪内容的效应在时间上先于注意力的效应,且先前文献中的差异可能源于功能磁共振成像(fMRI)信号的时间特征。尽管两项研究都为大脑中情感反应的时间展开提供了重要见解,但这里讨论了几个对其结果有影响的问题。因此,现在可能还不是接受“自动性是一个时间问题”这一结论的时候。事实上,情绪和注意力之间的联系可能比这里讨论的两项研究所表明的更为紧密。
