Eye movements and examples of postscan drawings. A, Representative examples of fixation locations (cyan circles) during the imagination phase of a single trial of each task are overlaid on a blank white screen on which participants focused their imagination (left). A visual representation of what participants were asked to imagine on the screen is shown to the right of each panel. Note the central focus of fixations for the Imagine Fixation and Imagine Objects tasks, the more dispersed pattern over the bottom two-thirds of the screen for the Imagine 2D Grid and Imagine 3D Grid tasks and the three clusters for both the Construct Array and Construct Scene tasks representing the locations of the imagined objects. B, The mean variance (±1 SEM) of fixations on the x coordinate during the imagination phase of each task. C, Representative examples of postscan drawings for the Construct Array (left) and Construct Scene (right) tasks.
