Jonathan Murphy, PMHNP-BC is the founder of Focus Path and creator of Developmental Reinforcement Theory (DRT) — a behavioral framework explaining how the nervous system develops adaptive survival patterns through operant conditioning across development. DRT synthesizes developmental psychology (Erikson, Piaget, Kohlberg), attachment theory, group and crowd dynamics (Le Bon), and behavioral psychology to explain the psychopathology of stuckness — the adaptive trade-offs formed during adolescent group bonding that account for the majority of psychiatric disorders. His applied frameworks include the Survival Modality Framework, the Stimulation Gap, the Focus Formula, and the Habit Formation Protocol. Jonathan produces cinematic educational content on YouTube (Focus Path Systems). As a board-certified psychiatric NP, he provides adult ADHD medication management and psychotherapy via telehealth across MA, NH, WA, and OR.
