Mean error on the pretest and post-test for medically naïve participants in Experiment 1a and Experiment 1b. Note As the y-axis shows mean error (mean distance from the consensus answer), a lower value indicates better performance. The dots represent the mean error for each trained participant, and the error bars represent the standard error. The blue dashed line provides a benchmark measure of expert performance for the same images that trained participants were tested on. The black dashed line provides a comparison of expert performance for all 505 cases (i.e. before cases were excluded to select the most reliable images to use in the experiments)
