Behavioral architecture
The behavioral architecture of INR in organizations.
Organizations attempt to influence behavior through goals, structures, and interventions. Self-Determination Theory demonstrate that the quality of motivation determines how sustainable this behavior is. Autonomous motivation leads to engagement and well-being, controlled motivation to stress and exhaustion.
However, motivation quality alone does not explain how behavior becomes part of professional identity. Self-Perception Theory explains how individuals observe their behavior and draw conclusions from it about who they are.
Source 01
Self-Determination Theory
Explains the quality of motivation and how sustainable behavior arises.
Source 02
Self-Perception Theory
Explains how behavior becomes part of professional identity.
INR connects both into a chronological chain.
01
Organizational context influences need fulfillment
02
Needs fulfillment influences quality of motivation
03
Motivation quality influences behavioral choices
04
Behavioral choices influence self-interpretation
05
Self-interpretation influences future motivation and performance
The innovation of INR does not lie in introducing new psychological principles, but in the systematically connection from motivation quality and self-interpretation to an applicable behavioral architecture for organizations.
