The invention relates to a method and an electronic device for implementing the method for measuring mental load. The electronic device generates at least two different cognitively loading tasks for the person participating in the measurement, the first task determining a reference level and at least one other task determining the loading capacity level. The electronic device determines the pulse parameters of the person participating in the measurement during the cognitively loading tasks. The electronic device also compares the pulse parameters during the different tasks with each other. Finally, the electronic device generates a value descriptive of the mental load of the person participating in the measurement on the basis of the comparison of the pulse parameters.
