Learning Objectives 1. Identify the four functions of behavior (escape, attention, access, sensory) and the limits of relying on function alone. 2. Describe six core yearnings—belonging, competence, coherence, self-directed meaning, orientation, feeling—through an ACT-informed lens. 3. Examine an assessment tool for evaluating how core yearnings show up for clients, for a more neuroaffirming picture of the behavior.
