1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

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