Test to Turn Shapes for Mind

For 1971, Roger Shepard and Jacqueline Metzler show people pairs of drawings of block shapes and ask dem whether di two na di same object or mirror images. Di more dem turn one shape, di longer e take people to answer, and di time grow in a straight line with di angle 1. E be like say people dey turn di shape for dia mind with steady speed. Dis finding na one of psychology classics.

E dey measure how you dey think about space: how correct and how quick you fit imagine say object dey turn. Dis version use our own flat shapes wey square make, and we draw dem fresh every time person run am, instead of di original 3D drawings, so you no fit compare di numbers with published studies.

• Di shape for left side dey upright. Di one for right side don turn reach 180° either way, and for about half of di pairs, person don flip am like mirror image. No turning fit make mirror image match di original.
• 4 practice pairs wey get feedback come first (you fit skip dem), then 24 pairs wey count. Tap Same or Mirror, or press S or M.
• If you no answer one pair within 8 seconds, e go count as miss. If you comot from di page, di run go end because dem dey time di test.

• How many you answer correct: di share of pairs wey count wey you answer correct.
• Time for each correct answer: your average time for di pairs wey you answer correct. We still show am by angle, so you fit see whether bigger turns take you more time, like wetin happen for di original study.

Practice dey make dis task faster, and your device plus di size of your screen fit affect am too, so compare am with your own earlier runs. If you want another test about space, try di test for picture memory.
