An example of quality control. Each block consisted of 150 trials and 150 rest intervals, with 10 rest intervals randomly selected for quality control. For example, in one block, trial 14 was selected, with the correct answer being ‘Today’s dinner tasted great’. To minimize participant movement, researchers communicated orally with the participants to confirm the accuracy of their responses.
