This document summarizes research on Action Science and Subject-Object Theory and how they can be combined to help adults overcome ineffective behaviors. It first reviews Action Science, developed by Argyris and Schon, which examines how individuals' governing values and mental models often lead to "Model I" behaviors that reduce effectiveness. Model I behaviors are driven by desires for unilateral control, to avoid loss and negative emotions, and prioritize rationality. The document then reviews Subject-Object Theory, which examines stages of adult development. It argues that combining these approaches could improve methods for helping adults recognize ineffective behaviors and mental models in order to develop "Model II" behaviors that support double-loop learning and increased effectiveness.
