This volume focuses on topics at the intersection between neuroethics and neurodevelopment, and brings together the perspectives of experts in both clinical assessment and intervention, and researchers in child psychology, neurosciences, medicine, health policy, law, and social work. The goal is to review emerging issues related to the ethical ramifications of how variation in human neurodevelopment is described, and the effects of these descriptions on those with lived experience, clinical and intervention services, and health and social policy. Related topics are also explored including the effect of the Covid-19 pandemic, the ethics of invasive neurotechnology interventions, biomarkers, machine learning, precision medicine.
