“…Moreover, this facilitation effect of stress on T2 only appears under neutral conditions, not under negative conditions. Several studies have confirmed that individuals have a more severe attentional bias to threat stimuli under stress, resulting from the delayed disengagement toward threat (Luo et al, 2019;Macatee, Albanese, Schmidt, & Cougle, 2017;Nelson, Purdon, Quigley, Carriere, & Smilek, 2015;Wirz, & Schwabe, 2020), which makes it difficult to shift attentional resources from T1 to T2. Therefore, the person under stress needs to make every effort to deal with the resource occupation and attention release of negative T1, leading to insufficient resources for the early selective attention processing of T2.…”

“…Specifically, in the second stage, the individuals first need to select the target consciously from many distractors and then encode it into working memory. Under stress, there are fewer available resources for T2 early processing after a negative T1 than a neutral T1 (Luo et al, 2019;Macatee et al, 2017;Nelson et al, 2015); hence, stress increases target selection in the second stage only under the neutral condition. The emotional information confusion in the second stage of working memory consolidation leaves the same resource for T2 processing (Alomari et al, 2015); therefore, stress does not affect this process.…”

The present study is the first to examine the time-dependent mechanism of acute stress on emotional attentional blink (EAB) with event-related potential (ERP) measures. We explored the stage characteristics of stress affecting EAB, whether it affects the early selective attention process (marked by early posterior negativity) or the late working memory consolidation (marked by late positive potential). Sixty-one healthy participants were exposed to either a Trier Social Stress Test (TSST) or a control condition, and salivary cortisol was measured to reflect the stress effect. ERPs were recorded during an attentional blink (AB) paradigm in which target one (T1) were negative or neutral images. Results showed stress generally reduced AB effects. Specifically, stress promoted the early selective attention process of target two (T2) following a neutral T1 but did not affect T2 consolidation into working memory. Correlational analyses further confirmed the positive effect of cortisol and negative emotional state on AB performance. Moreover, the ERP results of acute stress on AB conformed to the trade-off effect between T1 and T2; that is, stress reduced T1 late working memory consolidation and improved T2 early selective attention process. These findings further demonstrated that stress did not change the central resource limitation of AB. In general, stress generates a dissociable effect on AB early-and late-stage processing; namely, acute stress reduce the AB effect mainly from the improvement of participants' overall ability to select the targets in the early stage.

“…Acute stress has profound effects on attentional processing through activation of hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS) (Arnsten, 2009; Luo et al, 2020). Recent models of visual attention selection implement target enhancement (or target facilitation, directly boosting relevant information) and distractor suppression (suppressing irrelevant information) as independent processes that resolve the competition of simultaneously presented stimuli for attentional resources (Liesefeld & Müller, 2019; Wyble et al, 2020).…”

“…Previous studies have shown that salient stimuli can capture attention in a bottom-up manner(Gaspar & McDonald, 2014; Gaspelin & Luck, 2018). Furthermore, Several studies have demonstrated that stressed individuals are more easily distracted by task-irrelevant threatening (salient) stimulus(Luo et al, 2020; Wirz & Schwabe, 2020). Gaspar & McDonald (2018) found that in the high-anxiety group, the N2pc components appeared earlier compared to the low-anxiety group when a salient distractor appeared, indicating that individuals with high anxiety were less able to suppress distracting information and slower to do so.…”

Acute stress has a profound effect on attention selection, however, it remains unclear how acute stress affects target enhancement and distractor suppression in attention selection. The current study aimed to investigated the acute stress effect on target enhancement and distractor suppression in a visual search task by using ERP. The stress response was successfully induced as indexed by the activation of HPA and the subjective affect rating. Crucially, acute stress group showed significant smaller N2pc than the control group in the high-salience distractor condition, no significant differences of Pd was observed, which indicated that actue stress disrupts the target enhancement rather than the distractor suppression in attention selection. The detrimental effects might attribute to the impairing function of prefrontal cortex. The current study provide clear evidences of the impairment of target enhancement under acute stress, and reveal the cognitive mechanism of acute stress effects on attention selection.
