Humans prioritize stimuli related to themselves rather than to other people. How we control these priorities is poorly understood, though it is relevant to the nature of self-processing and a wide range of neurological and neuropsychiatric disorders, from cases of strokes, dementia to depression and schizophrenia. We update the Self-Attention Network proposed in 2016 by evaluating how self-prioritization interacts with Peterson and Posner's three attentional systems: alerting, orienting and executive control, based on evidence on a variety of behavioral and neuroscientific studies with healthy participants and patients with brain lesions. We suggest that all the three attentional networks contribute to self-prioritization. Understanding the nature of self-prioritization in attentional contexts may provide important clinical implications for a variety of disorders related to self-processing.
