Stimuli, task, and experimental procedure. A, Four 3D objects were used in this study: bed, bench, chair, and table. Each participant was randomly assigned two of these objects to view and draw repeatedly (trained); the remaining two objects were viewed but never drawn (control). B, Before and after the production phase, participants viewed all objects while performing a 2AFC recognition task. C, On each trial of the recognition phase, one of the four objects was briefly presented (1000 ms), followed by a 900 ms response window. On each trial of the production phase, one trained object was presented (3 s), followed by an 35 s drawing period (i.e., 23 TRs).
