The global population has been significantly affected by the pandemic in terms of physical and mental health. According to transactional theory, individuals have undergone an adaptation process influenced by cognitive control abilities. Emotional responses to COVID-19-related stimuli may interfere with top-down attentional processes, thereby hindering adaptation. This study aimed to investigate the impact of COVID-19-related stimuli on attentional processing and to determine whether psychological factors could modulate these effects. A sample of 96 healthy undergraduate students participated in an emotional Stroop task in which they were presented with a series of stimuli, including both neutral and negative COVID-19-related as well as non-COVID-19 stimuli. COVID-19-related PTSD, as an index of distress (PTSS), and trait anxiety were evaluated. Results showed that participants were more accurate in identifying COVID-19-related stimuli compared to non-COVID-19 stimuli. Being female and having higher retrospective PTSS scores related to COVID-19 were predictive of faster reaction times for both neutral and negative COVID-19-related stimuli. This heightened attentional bias toward COVID-19-related stimuli suggests that individuals may be more sensitive to stimuli associated with the pandemic. The results suggest that the association between COVID-19 stimuli and attentional biases extends beyond emotional valence, being retrospectively influenced by mental health, suggesting potential pathways to future mental health challenges.

The pandemic period which has characterized the last two years has been associated with increasingly worsening psychological conditions, and previous studies have reported severe levels of anxiety, mood disorder, and psychopathological alteration in the general population. In particular, worldwide populations have appeared to present post-traumatic stress symptoms (PTSS). Surprisingly, no studies have evaluated the effect of COVID-related PTSS on cognitive functioning. This study focused on the association between high levels of PTSS related to COVID-19 and alterations in executive functioning by considering executive inhibitions in populations not infected by the virus. Ninety respondents from the Italian population participated in the study. A higher percentage of PTSS was reported. Moreover, respondents with high post-traumatic symptomatology presented deficits in the inhibition of preponderant responses, demonstrating an executive deficit which could be expressed by a difficulty in controlling goal-directed actions. This was underlined by worse performances in elaborating incongruent stimuli in the Stroop task and no-go stimuli in the Go/No-Go task. This report presents preliminary findings underlining the effect of the COVID-19 pandemic on cognitive functions. The results confirmed a persistently higher post-traumatic symptomatology related to the COVID-19 pandemic in the Italian population and highlighted an association with cognitive inhibition impairment.
