Behavioral Cusp

Full Definition

A behavioral cusp is a behavior that, once learned, provides access to new contingencies of reinforcement and learning opportunities that were previously unavailable. These pivotal behaviors have far-reaching effects beyond their immediate function, often leading to rapid expansion of behavioral repertoires and developmental progress. In behavioral medicine, identifying and targeting behavioral cusps can maximize treatment efficiency by producing broad-based improvements from focused interventions.
