Recording of the exact timing and accuracy of each word, however, is difficult in the laboratory. The instructions are to name the colors as fast as possible without making mistakes. Different people will use different strategies and trade off one vs. the other. They also self-correct a lot when they say the wrong color. In our case, there was a set time for each block. If participants finished the list before the block ended, they could manually discontinue by pressing a button. The block will then be shown as ended in Acqknowledge. However, if the participant took longer than the provided time, they were cut off in the middle of the naming list. We are not interested in the exact cognitive performance (i.e. time and accuracy), but the physiological reactions to this task, as it is cognitively demanding and therefore more “stressful”.
