Heid-turnin Test

In 1971, Roger Shepard and Jacqueline Metzler shawed fowk pairs o drauchts o block shapes, and spiered gin the twa war the same object or mirror-bilds. The mair ane shape wis turned, the langer fowk took tae answer, and the time grew in a straicht line wi the angle 1. It leukit as gin fowk war turnin the shape in their heids at a steady speed. The findin is ane o the classics o psychology.

It measures spatial thinkin: hoo accurately and hoo quickly ye can imagine an object turnin. This version uses oor ain flat shapes made o squares, drawn new for ilka run, insteid o the original 3D drauchts, sae its nummers cannae be compared wi published studies.

• The left shape is upricht. The richt yin is turned bi up tae 180°, either wey, and in aboot hauf o the pairs it's flipped as weel, like a mirror-bild. Nae turn can mak a mirror-bild match the original.
• 4 practice pairs wi feedback come first (ye can skip thaim), then 24 coontit pairs. Tap Same or Mirror, or press S or M.
• A pair ye dinnae answer within 8 seconds coonts as a miss. Leavin the page ends the run, acause the test is timed.

• Answert richt: the share o coontit pairs ye got richt.
• Time for ilk richt answer: yer average time on the pairs ye got richt. We shaw it bi angle an aa, sae ye can see gin bigger turns took ye langer, as in the original study.

This task gets quicker wi practice, and yer device and the size o yer screen matter an aa, sae compare wi yer ain earlier runs. For anither spatial test, try the sicht mindin test.
