Summary - The Neuroscience of Imposter Syndrome: Ancient Circuits, Modern Doubts

Imposter syndrome is not personal failure. It is a human phenomenon born of ancient neurobiology built for survival—not our complex, modern network of pressures.

This workshop will map how inherited threat and stress processes interact with contemporary social dynamics to create fertile ground for self‑doubt. Then, we will clarify why common cognitive tools often fall short, and we will examine the foundational, psychophysiological mechanisms that support more durable, brain‑based neuroplastic change.

Dr. Kymberlee O'Brien is an Assistant Professor in the Department of Organizational and Leadership Psychology at William James College and Faculty in the Clinical Psychology Department. She is primarily a faculty member of the Neuroscience of Leadership Psychology concentration, where she teaches, supervises, and advises concentration students. Dr. O'Brien is committed to supporting her students' learning and development. Dr. O’Brien is the owner of NeuraLight Consulting LLC. She earned her PhD in Social Psychology with a specialization in Psychophysiology from Brandeis University in 2011, where she was mentored by Professor Arthur Wingfield, the Neuroscience Director. Her dissertation, which garnered the APA Dissertation Award, centered on Moral Decision Making Under Stress. Following her PhD, she completed a four-year post-doctoral fellowship in Developmental Psychobiology at UMass Boston/Harvard Medical School in 2014. Dr. O'Brien was also honored as a Harvard University Sackler Scholar Fellow in Psychobiology, recognized by the American Psychological Foundation Visionary Award, and received the National Institutes of Health NLP award for her research on psychophysiological health disparities. Recently, she was funded by the Massachusetts Cultural Council for her programming: Brain Fitness Across Multiple Domains (2025). Her research focuses on acute and chronic social stress, as well as awe and flourishing experience as the protective and reparative processes that can mitigate these impacts. She is particularly interested in the psychophysiological processes underlying emotion regulation, social engagement, and leadership and followership processes. Her funded research has largely focused on the biological correlates of bias and intergroup processes. Currently, she is leading the redesign of the Neuroscience of Leadership lab at William James College, expanding its scope to include broader neurophysiological studies that assess acute and chronic stress through neuroendocrine and autonomic parameters related to social processes.

Identify at least four brain systems implicated in impostor syndrome (amygdala, ACC, insula, DMN) and describe their functional roles in social evaluation and self-concept;
Explain how neurochemical systems (HPA axis/cortisol, dopamine prediction error signaling, oxytocin, serotonin) contribute to persistent self-doubt and under-recognition of achievement;
Critique at least three commonly used strategies (e.g., affirmations, “fake it till you make it,” generic CBT) and articulate two neuroscience-based reasons why these tools often lack sustained impact;
Discuss advanced neuroscience-informed interventions—including interoceptive retraining, polyvagal-informed safety cues, and oxytocin-based attunement—and describe their theoretical basis for reducing impostor cognitions;
Describe how integrating cognitive reframing with physiological state regulation enhances emotional encoding, retention, and generalization of learning; and
Summarize at least two metrics for evaluating progress (validated self-report scales, behavioral experiments) and outline considerations for long-term maintenance.
