“…The N1 and P2 components, which was associated with psychological indicators in the current study reflects exogenous automatic attention, and it is noted to be related to early emotion processing for N1 amplitude (Keil et al, 2001;Foti et al, 2009;Gable and Harmon-Jones, 2012), recognition processes for P2 amplitude (Halit et al, 2000). In an ERP study investigating emotional processing in social anxiety, the N1 amplitude to facial stimuli increased in the high social anxiety (HSA) group as compared with that in the low social anxiety group, which means that the HSA group showed an early attentional bias to facial expressions (Felmingham et al, 2016). The ERP study investigating attentional bias in obsessive-compulsive disorder (OCD) reported that the N1 and P2 amplitudes to OCD-related expression stimuli increased in the OCD group as compared with the healthy control group (Zhang et al, 2017).…”

Introduction: Attention bias towards pain-related information exists in patients with chronic pain, and recently, attention bias modification (ABM) training has been administered to patients with chronic pain. In this study, we conducted an attention bias modification task in conjunction with event-related potential measurements for individuals with chronic low back pain (LBP) and investigated the relationship between attention bias and psychological assessment. Methods: Eleven women and two men with chronic LBP participated in the study. Results: The Japanese version of the STarT Back Screening Tool (J-SBST) total score was significantly correlated with the N1 amplitude of Cz. The J-SBST psychological score was significantly correlated with the N1 amplitude of Cz and with reaction time (RT). The Japanese version of the Pain Catastrophizing Scale (PCS) and Japanese version of the Beck Depression Inventory-Second Edition (BDI-II) scores were significantly correlated with the P2 amplitude at Fz (only PCS), Cz, and Pz. Conclusions: Our findings suggest that J-SBST, which provides a comprehensive evaluation of psychological factors, PCN with measuring of catastrophizing in the context of actual or anticipated pain, and BDI-II, can likely help identify chronic LBP patients with attention bias. For chronic LBP patients who are classified according to J-SBST or PCN pain-related outcome improvement with ABM training can be expected.

“…Reduced function of this system, postulated to avert a sensory load of threatening stimuli, may result in overgeneralization to nonthreatening stimuli. In fact, larger N1 amplitudes occurring in response to nonthreatening stimuli have also been found in other populations prone to high levels of anxiety, such as those with panic attacks (Wise, McFarlane, Clark, & Battersby, ) and social anxiety (Felmingham, Stewart, Kemp, & Carr, ); such findings have also been considered indicative of hypervigilance of early automatic attention. Thus, the current study, taken together with these previous research findings, may pinpoint a general hypervigilant information‐processing pattern unconfined to trauma‐related stimuli that could be indicative of a decrement in cortical modulation.…”

Early automatic hyperarousal in response to neutral novel auditory stimuli among trauma‐exposed individuals with and without PTSD: An ERP study

ERP studies have associated posttraumatic stress disorder (PTSD) with enhanced P3 amplitudes in response to trauma-related stimuli, along with reduced amplitudes in the context of neutral (trauma-unrelated) stimuli. Additionally, a bias toward trauma-related stimuli is also observed among trauma-exposed participants not meeting criteria for PTSD, suggesting that trauma exposure itself, and not only the severity of posttraumatic stress (PTS), is a critical factor in information processing changes. However, previous examination of the response of trauma-exposed (PTSD and non-PTSD) participants to novel, neutral stimuli has produced conflicting findings. The current study examined ERPs in response to a novelty oddball paradigm comprised of neutral distractor sounds. Participants were 16 individuals with PTSD, 21 trauma-exposed individuals without PTSD, and 12 nontraumatized controls. Detailed trauma histories and PTS symptoms were collected. A significant effect of group on early ERPs was observed, showing an increase in the N1-P2 complex peak amplitude among the PTSD group, relative to controls. Among the entire sample, significant positive correlations were observed between PTS symptom severity, as well as trauma history, and early N1-P2 complex peak amplitudes, in response to novel stimuli. Furthermore, trauma-exposed participants with no PTS symptoms exhibited larger N1 amplitudes compared to participants with no trauma history. No trauma-related alterations in later ERP components were observed. These results suggest that trauma exposure may lead to hyperarousal at early processing levels, even in response to neutral novel stimuli. The findings concur with the neurocircuitry model that associates PTSD with hyperresponsivity of the amygdala.

“…In general, larger N1 amplitudes that occur in response to nonthreatening stimuli have been found in populations prone to high levels of anxiety, such as panic attacks (Wise et al 2009), social anxiety (Felmingham et al 2016), and PTSD (Zukerman et al 2018). The N1 was specifically enhanced in those with PTSD in a study done by Zukerman et al (2018) when participants were presented with the auditory novelty oddball paradigm to discriminate between target, novel, and standard tone.…”

Expect the unexpected: Processing of sensory information in the anticipation of predictable and unpredictable threats

Anxiety is characterized by a sustained state of heightened vigilance due to uncertain danger, producing increased attention to a perceived threat in one's environment. To further examine this exploited the temporal resolution afforded by event-related potentials to investigate the impact of predictability of threat on early perceptual activity. We recruited 28 participants and utilized a within-subject design to examine hypervigilance in anticipation of shock, unpleasant picture and unpleasant sound during a task with unpredictable, predictable and no threat. We investigated if habituation to stimuli was present by asking the participants to rate unpleasantness and intensity of the stimuli before and after the experiment. We observed hypervigilance in the unpredictable threat of shock. Habituation was observed for the visual stimuli. The present study suggests that unpredictability enhances attentional engagement with neutral somatosensory stimuli when the threat is of the same modality, meaning we observed the presence of hypervigilance which is a characteristic of anxiety.
