Cognitive biases are an important factor contributing to the development and symptom severity of psychosis. Despite the fact that various cognitive biases are contributing to psychosis, they are rarely investigated together. In the current systematic review, we aimed at investigating specific and shared functional neural correlates of two important cognitive biases: aberrant salience and source monitoring. We conducted a systematic search of fMRI studies of said cognitive biases. Eight studies on aberrant salience and eleven studies on source monitoring were included in the review. We critically discussed behavioural and neuroimaging findings concerning cognitive biases. Various brain regions are associated with aberrant salience and source monitoring in individuals with schizophrenia and the risk of psychosis. The ventral striatum and insula contribute to aberrant salience. The medial prefrontal cortex, superior and middle temporal gyrus contribute to source monitoring. The anterior cingulate cortex and hippocampus contribute to both cognitive biases, constituting a neural overlap. Our review indicates that aberrant salience and source monitoring may share neural mechanisms, suggesting their joint role in producing disrupted external attributions of perceptual and cognitive experiences, thus elucidating their role in positive symptoms of psychosis. Account bridging mechanisms of these two biases is discussed. Further studies are warranted.

COVID-19 pandemic is a global challenge that affects people’s mental health worldwide. Experiencing anxiety by children and adolescents, who are vulnerable to the impact of sustained stressors during developmentally sensitive periods, can lead to long-lasting effects on their health. The article brings insight into the short and long-term consequences of the COVID-19 pandemic on the children and adolescents’ mental health. The particular aim of this study is to investigate the relationship between anxiety, stress, and resilience in young individuals in the context of COVID-19. A review of the psychological effects of pandemic on children and adolescents was done using electronic databases. Most reviewed studies reported risk factors of psychosocial problems among children and adolescents during pandemics, resilience and positive coping as protective factors for the occurrence of anxiety and stress symptoms, and mediating role of parents’ stress impact on children’s behavioral and emotional problems. Clinical implications are discussed and additional research is suggested.
