Ballard's block-copying task, illustrating the most common visual strategy by participants. Typically, participants fixate a block in the model (1) before fixating a block of the corresponding colour in the source area (2). Once the block is picked up and in transit towards the copy area (dashed grey arrow), a refixation of the block in the model is made (3), presumably to gather information about where to place the selected block. Finally, the location at which the block will be placed is fixated (4).
