Emotional and Attentional Bias in Fibromyalgia: A Pilot ERP Study of the Dot-Probe Task

Abstract

Introduction:The present research investigates the neural correlates of attentional bias in fibromyalgia (FM) with a dot-probe task performed during an electroencephalogram (EEG) recording. Methods: For this purpose, 30 female participants were recruited, divided into two groups: a group of patients with FM (FM, n = 15, M age = 51.87) and a healthy control group (HC) (HC, n = 15, M age = 46.13). Results: The results did not show behavioral differences between groups, but the EEG results showed that healthy controls had larger P300 amplitudes than patients with FM. Regarding late positive potentials (LPP), we found that patients with FM had larger amplitudes than healthy controls in a later time window. Conclusion: In summary, while the P300 results suggest that patients allocate less attentional resources to the task, the increased amplitudes of their LPP suggest augmented emotional processing of the target stimuli. Altogether, our results seem to support the thesis of generalized attentional deficits in FM.

“…Other studies seem to support the thesis of generalized attentional deficits in FM and augmented emotional processing of the target stimuli [ 28 – 30 ].…”

“…The visual analogue scale was used to evaluate pain intensity, sleep quality and fatigue. This interview was used in another previously published study [ 28 ]. The interview guide is in the supplementary material.…”

Different Educational Interventions on Individual Cognition of Garbage Classification Based on EEG Monitoring

“…Alicart et al (2020) identified that gossip information was more deeply remembered than trivia, and the related P300 amplitude was larger, indicating that it was positively related to the attention state [49]. Cardoso et al (2021) tried to distinguish the cognitive processes expressed by P300 and LPP, in which the former was associated with concentration, whereas the latter was more closely related to emotional changes [50]. Liu et al (2022) used P300 to explore the impact of social norms on the willingness to use recycled water.…”
