Example of a 25-s trial. In this example, the participant managed to complete five of the six spirals. The participant had to draw each spiral counter clockwise, starting from the centre yellow circle. Participants had to start with the top-left spiral and move in a clockwise order, hence the last spiral of the trial was on the bottom-left. The dotted lines were not displayed for the task; they have been added to illustrate the data analysis presented in the next section.
