Mental rotation of three-dimensional objects.
نویسندگان
چکیده
The time required to recognize that two perspective drawings portray objects of the same three-dimensional shape is found to be (i) a linearly increasing function of the angular difference in the portrayed orientations of the two objects and (ii) no shorter for differences corresponding simply to a rigid rotation of one of the two-dimensional drawings in its own picture plane than for differences corresponding to a rotation of the three-dimensional object in depth.

Mental rotation: effects of dimensionality of objects and type of task.
The original studies of mental rotation estimated rates of imagining rotations that were much slower when two simultaneously portrayed three-dimensional shapes were to be compared (R. Shepard & J. Metzler) than when one two-dimensional shape was to be compared with a previously learned two-dimensional shape (Cooper and her associates). In a 2 X 2 design, we orthogonally varied dimensionality of...
متن کاملTwo- vs. three-dimensional presentation of mental rotation tasks: Sex differences and effects of training on performance and brain activation
The well-documented sex difference in mental rotation favoring males has been shown to emerge only for 2-dimensional presentations of 3-dimensional objects, but not with actual 3-dimensional objects or with virtual reality presentations of 3-dimensional objects. Training studies using computer games with mental rotation-related content have demonstrated training effects on mental rotation perfo...
متن کاملPerceptual illusion of rotation of three-dimensional objects.
Perspective views of the same three-dimensional object in two orientations, when presented in alternation, produced an illusion of rigid rotation. The minimum cycle duration required for the illusion increased linearly with the angular difference between the orientations and at the same slope for rotations in depth and in the picture plane.
متن کاملDetection of three-dimensional objects under arbitrary rotations based on range images.
In this paper a unique map or signature of three dimensional objects is defined. The map is obtained locally, for every possible rotation of the object, by the Fourier transform of the phase-encoded range-image at each specific rotation. From these local maps, a global map of orientations is built that contains the information about the surface normals of the object. The map is defined on a uni...
متن کاملA New Set of Three-Dimensional Shapes for Investigating Mental Rotation Processes: Validation Data and Stimulus Set
Background Few experiments in the history of psychology have spurred as much research interest as the seminal paper by Shepard and Metzler [1] on the mental rotation of drawings of three-dimensional objects. As of the writing of this article, according to Web of Science the original paper has been cited more than 2000 times, and there have been more than 5000 studies on mental rotation. These s...
