Introduction Top-down mechanisms that regulate attentional control are influenced by task demands and individuals’ goals, while bottom-up processes salient stimuli. Analogous networks involved in both (e.g., frontostriatal areas). However, they affected differently the emotional salience of stimuli, which determines allocation attention. This study aims to determine whether recent pandemic experience continues exert an influence on cognitive processes. To this end, will biases toward pandemic-related stimuli compared negative neutral Furthermore, investigate top-down latter affect autonomic as indexed Heart Rate Variability (HRV). Methods Ninety-six undergraduate students completed a Flicker Task with categorized valence (neutral, non-COVID, COVID-related). paradigm involves presentation two different pictures, identical except for specific detail. The required detect detail has been changed. Given employs images natural scenes, participants tend focus more areas scene than others. As result, changes central interest (CI) detected rapidly marginal (MI) areas. Participants’ response times (RTs) at their HRV data were used assess performance associated nervous system activity. Results results indicate slower responses COVID-related CI MI changes, requiring involvement (CI changes) (MI was detection scenes. Discussion These findings highlight intricate interplay between salience, mechanisms, physiological threatening Contextual factors, particularly those related stress, processing its relationship
