Two representative trials and probability distributions of fixation durations from Experiment Two. Top two rows: Gaze events (saccades in gold and fixations in magenta) for TMT-A (left) and TMT-B (right) tests for two representative participants (S1 and S2). The last row shows probability density functions of fixation durations for TMT-A (left bottom panel) and TMT-B (right bottom panel) performed by 37 healthy, young controls (subset of all the participants). The red vertical lines show the mean value for the two distributions (302 and 326 ms respectively) and the green lines show the medians of the two distributions (207 and 214 ms respectively)
