Mental Causation and Motivation: The Motivational Congruence Theory's Perspective.

Mental causation is a deep-rooted debate in the philosophy and psychology literature. It relates to the causal role of mind on the physical world and is tightly linked with the Descartes' dualistic approach towards mind-body interaction. While the role of mental properties might seem obvious in our everyday interaction with the world, there are many arguments that make mental causation inefficacious or redundant within the physical world. In the motivation literature, the issue of mental causation is pivotal. It substantiates the causal role of intrinsic motivation on human behavior. However, the main theoretical streams in the motivation literature take a dualistic approach by dichotomizing different types of motivation into extrinsic and intrinsic ones. This creates a fundamental challenge on the possibility of mental causation in the relationship between motivation and behavior. The three main theoretical streams in the motivation literature consider intrinsic and extrinsic motivations as distinct and independent types of motivation and give a higher weight to one type over the other. This approach makes the role of intrinsic motivation as a mental factor on behavior difficult to interpret. Motivational congruence theory resolves this issue by taking a contextualist and dialectical stance on the relationship between intrinsic motivation, extrinsic motivation, and the context. In a dynamic interaction with each other and the context, the two distinct yet intertwined types of motivation (i.e., intrinsic and extrinsic ones) produce overall motivation which in turn induces behavior. The theory resolves the issue of mental causation both at the surface and deep levels.
