--- - |2 Abstract Neuroscience has already changed the understanding of how intent forms and is acted upon, how an individual's cognitive processes shape behavior, and how bio‐psychosocial history and neurodevelopmental approaches provide information that has been largely missing from the assessment of intent. In this paper, we first review the state of forensic assessment of mental condition and intent, focused primarily on the weaknesses of the current approach. In Section 2, we discuss neurobehavioral forensic assessment, which is a neuroscience‐based approach. Section 3 focuses on the changing understanding of mental illness and how neuroscience is pushing law towards a functional capacity‐and‐ability model and away from a diagnostic cut‐off model. Finally, in Sections 4 and 5, we turn to the role of social and environmental context in shaping behavior and propose a model of behavioral intent in line with the scientific evidence. - Behavioral Sciences & the Law, Volume 36, Issue 4, Page 411-425, July/August 2018.
