Mental Rotation Stimuli (Giorgio Ganis)

 

Description: This data set contains the individual files (in PICT format) used in the study cited below and a .tar archive with all the files. The set has 47 ¬†Shepard and Metzler figures and their mirror images. This set is especially useful for training studies in which shape repetition would be problematic.The file naming conventions are as follows. The first 4 numbers are the number of blocks in the four arms of the figure. The fifth number can be 0, 90 or 180. It’s a rotation factor of part of the figure (basically, one can generate more then one shape for a given set of 4 arm lengths). The number after the ‘Y’ is the angle of rotation between the shapes (3 angles, 50, 100, and 150). Finally, if the filename starts with ‘R’, it means that the two shapes are mirror-images of each other.
