INTEREST AND SCOPE The analysis and measurement of mental load is a topic of focal interest in contemporary basic and applied psychological sciences. It also has a strong appeal to folk psychology. When listening to conversations, one can often hear phrases such as: "You need to put your mind to it, concentrate, invest, devote attention"; "I cannot follow, this is too fast for me"; "The demands are too high". These are a few examples of common expressions that people


use to describe the demands, or the mental costs, of involvement in the performance of a given task. How are these experiences reflected in the scientific study of mental load?
