Heat maps of mouse movements by experiment and health literacy. Heat maps are shown for statements used in Experiment 1 (left panels) and tweets in Experiment 2 (right panels). The heat maps show incremental processing for many trials (i.e., there are smooth paths from the start button to the response button). However it is also apparent that overrides exist in the data (i.e., abrupt changes occur, especially near the response buttons). These overrides indicate that dual stage processing may happen late in the trials
