Motivation is a dynamic concept which fluctuates within the operator over time—it is not a binary state of either present or absent. Additionally, Self-Determination Theory purports that there is a fundamental difference between the two main categories of motivation: intrinsic and extrinsic. Intrinsic motivation drives behavior because the person perceives it as inherently satisfying, whereas extrinsic motivation drives behavior through only secondary rewards. However, factors such as the perceived satisfaction of basic psychological needs and cognitive and affective states (such as stress and workload) significantly affect motivation. Consequently, it is important to design a system that takes these factors into consideration in order to promote optimal performance of human-machine systems. Despite our understanding of motivation’s effects on human performance, many systems’ design erroneously assumes motivation is not only present in the operator whilst engaging with a task, but that the operator remains motivated throughout the course of performance. These assumptions are not only incorrect, but also fail to exploit aspects of motivation that could lead to better human performance within human-machine systems. The present study therefore examines how intrinsic motivation and operators’ cognitive and affective states (stress and workload) influence performance outcomes in terms of completion rates, speed, and accuracy in a goal-directed discretionary technological system (video games). Results pertaining to performance outcomes, measurements of the perceived satisfaction of basic psychological needs, and changes in cognitive and affective states are interpreted via the Self-Determination Theory of motivation.
