Which theory proposes that both internal and external motivational factors contribute to motivation?

The answer hinges on the understanding of the Social Learning and Expectancy theory. This theory emphasizes that motivation is influenced by both internal factors, such as an individual's beliefs, expectations, and self-efficacy, as well as external factors, including social influences and environmental cues.

By integrating these perspectives, the theory acknowledges that an individual's motivation to engage in a behavior is not solely driven by their internal desires or needs but is also significantly affected by their expectations of success and the reinforcements or outcomes they anticipate from their actions within a social context. This dual recognition of internal and external motivators offers a comprehensive view of what drives behavior in educational settings.

In contrast, other options primarily focus on distinct aspects of motivation without accounting for this interplay. For example, Extrinsic Motivation focuses specifically on external rewards rather than the balance with internal factors, while Triarchic Theory relates more to different types of intelligence rather than motivations. Structure of Intellect primarily deals with cognitive abilities and does not directly address motivational factors.
