Attention prioritizes stimuli previously associated with reward or punishment. The present study examined whether this attentional bias, widely considered to be involuntary and automatic, could be suppressed with sufficient motivation. Participants performed visual search for a shape-defined target. One color-singleton distractor predicted the possibility of receiving a reward and another an electric shock, with each outcome occurring infrequently. Participants were informed that the likelihood to earn a reward or avert punishment depended on fast and accurate performance, thus providing strong motivation to resist distraction by reward- and shock-related stimuli. Results revealed a reduction in the magnitude of attentional capture by reward- and threat-associated distractors, relative to neutral distractors, that persisted into extinction. In a second experiment, we replicated the suppression of value-modulated attentional capture in the absence of the shock condition, thus confirming that the suppression did not result from the presence of threat. Finally, in a third experiment, we replicated the typical pattern of attentional capture by reward cues using a more conventional procedure in which the motivation to suppress valent stimuli was low (the likelihood to be rewarded was high and not contingent on fast performance). This study demonstrates that signals for reward and threat can be actively suppressed with sufficient motivation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
注意优先处理先前与奖励或惩罚相关的刺激。本研究考察了这种注意力偏向是否可以通过足够的动机来抑制。参与者执行了视觉搜索任务,以寻找形状定义的目标。一种颜色单一的干扰项预示着获得奖励的可能性,另一种则预示着电击,每种结果都很少发生。参与者被告知,获得奖励或避免惩罚的可能性取决于快速准确的表现,从而提供了强烈的动机来抵制与奖励和威胁相关的刺激的干扰。结果表明,与中性干扰项相比,与奖励和威胁相关的干扰项对注意力的捕获程度降低,这种情况一直持续到消退。在第二个实验中,我们在没有电击条件的情况下复制了价值调节注意力捕获的抑制,从而证实这种抑制不是由威胁的存在引起的。最后,在第三个实验中,我们使用一种更传统的程序复制了奖励线索引起的典型注意力捕获模式,在这种程序中,抑制有价值刺激的动机较低(获得奖励的可能性很高,并且不取决于快速表现)。这项研究表明,奖励和威胁的信号可以通过足够的动机来主动抑制。(PsycInfo 数据库记录(c)2022 APA,保留所有权利)。
