Comparison of additional objects drawn beyond those in the images across conditions. a Average number of objects drawn for each drawing type that did not exist in the images (Category Drawing, Delayed Recall, Immediate Recall, Image Drawing). Participants drew few additional objects when recalling images regardless of delay and when drawing from the image. For Category Drawing, they often drew objects that did not exist in the images for that label, as expected since drawings were merely done from the category name. Dots represent each of the 60 images used in the experiment, with lines connecting the same image across conditions. Horizontal lines above the graph indicate significant pairwise Wilcoxon rank-sum test comparisons that pass a Bonferroni-corrected threshold of p < 0.0083. b Examples of additionally drawn objects from Delayed Recall, Immediate Recall, and the Image Drawings. Additional objects are circled and labeled below each drawing in orange. Participants drew additional objects in the Delayed Recall drawings, for example, adding a cactus to a desert scene, drawing a window not captured in the image, or adding a dining table to a kitchen. However, participants also drew additional objects when recalling the image immediately after seeing it, adding people to a mountain scene, or replacing a chef sculpture with a vase of flowers in a kitchen scene. Even more surprising, participants drew additional, non-existent objects when drawing from the image itself, also adding a cactus to a desert scene or people and cars to scenes that did not have any
