Abstract

Emotionally-salient stimuli receive attentional priority. Here, we tested the extent to which top-down control can modulate this prioritization within the domain of temporal attention. To test this prioritization, we measured emotion-induced blindness, which is the effect whereby the perception of a target is impaired by the presentation of a negative distractor that precedes the target in a rapid serial visual presentation stream, relative to target perception following a neutral distractor. The degree of top-down control was investigated by manipulating participants’ concurrent working memory load while performing the task. The working-memory load consisted of participants performing mathematical calculations (no load = no calculation; low load = adding two numbers; and high load = adding and subtracting four numbers). Results indicated that the magnitude of emotion-induced blindness was not affected by the working-memory load. This finding, when combined with those of previous studies, supports the notion that the prioritization of emotionally-salient stimuli in the temporal allocation of attention does not require top-down processing, while it does in the spatial allocation of attention.

情绪导致的失明对工作记忆负荷是不敏感的。
情绪上显著的刺激获得注意力优先。在这里,我们测试了自上而下的控制在多大程度上可以在时间注意力领域内调节这种优先级。为了测试这种优先顺序,我们测量了情绪诱导的失明,这是一种效应,即在快速的连续视觉呈现流中,相对于中性干扰物之后的目标感知,在目标之前出现的负面干扰物会削弱对目标的感知。通过操纵参与者在执行任务时的并发工作记忆负荷来研究自上而下的控制程度。工作记忆负荷包括参与者进行数学计算(无负荷 = 无计算;低负载 = 将两个数字相加;和高负载 = 加和减四个数字)。结果表明,情绪性失明的程度不受工作记忆负荷的影响。这一发现与之前的研究相结合,支持了这样一种观点,即在注意力的时间分配中,情感显著刺激的优先顺序不需要自上而下的处理,而在注意力的空间分配中则需要。补充信息:在线版本包含补充材料,请访问10.1007/s42761-022-00176-9。
