“…Three studies have examined the P300 and how it may relate to SI. The first did not find any relationship between the P300 and self-reported SI (g = −0.57; Baik et al, 2018). Another study among psychiatric patients found a significant, positive relationship between the P300 to a variety of stimuli during an affective incentive delay task and SI (Song et al, 2019).…”

Suicide is a concern around the world. Estimates indicate that well over 800,000 people die by suicide annually (World Health Organization, 2014). Many scientists have suggested that suicidal thoughts (i.e., thoughts related to desire for death or suicide, regardless of suicidal intent) and behaviors (i.e., suicide attempt with nonzero intent; death by suicide; Silverman et al., 2007) are partially the result of differences or abnormalities in neurobiological

“…This suggests that ERPs may be a more sensitive method than behavioural measures in capturing attentional bias in adolescents with suicidal behaviour. Previous studies using both clinical and non-clinical samples have also demonstrated that ERPs are more sensitive than behavioural measure for investigating attentional bias (60,(100)(101)(102)(103)(104).…”

Attentional Bias Deficits in Adolescent Suicide Attempters During an Emotional Stroop Task: An ERP Study

There is increasing evidence that, in adolescence, attentional bias plays a critical role in the vulnerability for suicidal behaviour. No studies to date have investigated the neurophysiological correlates of attentional bias in adolescent suicidality. The present study uses event-related potentials (ERPs) to investigate such processing in inpatient adolescents admitted for an acute suicide crisis using an Emotional Stroop Task (EST). In this task, participants are asked to name the colour of words varying in emotional valence (positive, negative, neutral, suicide-related). Suicidal individuals are hypothesised to be more preoccupied by the context of the suicide-related stimuli, which may interfere with their ability to perform the colour naming task. Seventeen adolescents with acute suicidal behaviour and 17 age- and gender-matched healthy controls performed an EST while ERPs were recorded. Suicide attempters showed increased reaction times to suicide-related words compared to other emotion categories, while the controls did not. The amplitude of the early posterior negativity (EPN) was not significantly different across groups or emotional valence. A double peak P3 (early-P3 and late-P3) was observed in both groups. Both the early- and late-P3 were significantly reduced in amplitude in the suicide attempter group compared to the control group, regardless of emotional valence. The late-P3 latency was also significantly delayed in the suicide attempters compared to controls. The behavioural findings support the attentional bias theories of suicide attempters and extend these findings to adolescents. Furthermore, large early- and late-P3 provide evidence that cognitive strategies employed by two groups did markedly differ.

“…In Experiment 3, visual targets elicited larger P300 amplitudes for positive auditory cues compared to neutral auditory cues on valid trials. Previous studies have shown that the amplitude of P300 was related to attentional resource allocation to emotional stimuli (Yee and Miller, 1994;Kessels et al, 2010;Willner et al, 2015), attentional disengagement with threat (Baik et al, 2018), the maintenance of attention (Bauer, 2021). Experiment 3 found that P300 amplitudes were higher for visual targets after positive auditory cues than those for visual targets after neutral auditory cues in valid trials, but not in invalid trials.…”

Recently, researchers have expanded the investigation into attentional biases toward positive stimuli; however, few studies have examined attentional biases toward positive auditory information. In three experiments, the present study employed an emotional spatial cueing task using emotional sounds as cues and auditory stimuli (Experiment 1) or visual stimuli (Experiment 2 and Experiment 3) as targets to explore whether auditory or visual spatial attention could be modulated by positive auditory cues. Experiment 3 also examined the temporal dynamics of cross-modal auditory bias toward positive natural sounds using event-related potentials (ERPs). The behavioral results of the three experiments consistently demonstrated that response times to targets were faster after positive auditory cues than they were after neutral auditory cues in the valid condition, indicating that healthy participants showed a selective auditory attentional bias (Experiment 1) and cross-modal attentional bias (Experiment 2 and Experiment 3) toward positive natural sounds. The results of Experiment 3 showed that N1 amplitudes were more negative after positive sounds than they were after neutral sounds, which further provided electrophysiological evidence that positive auditory information enhances attention at early stages in healthy adults. The results of the experiments performed in the present study suggest that humans exhibit an attentional bias toward positive natural sounds.
