Abstract: When solid objects are viewed from only 1 direction, some parts are necessarily occluded. Expectations about possible completions of novel objects (cubes with indentations) were measured by the response times to determine whether 2 images could be 2 depth-rotated views of the same object. Completions are considered global if the completed indentations are identical to the visible indentations (i.e., they are globally simple because of the repetitions) and are considered local if they are locally simple (e.g., straight contours with a minimal number of additional surfaces). The results of 3 experiments showed that local and global completion tendencies that were well established for 2-dimensional surfaces appear valid for 3-dimensional objects as well. Also, it is shown that structural object aspects play an important role in object completion.
