Road-drawin Test

The road-drawin task is ane o the maist uised tasks in psychology research. Pairt A, nummers in order, is maistly sicht-search an speed o muivin. Pairt B adds switchin atween twa sequences, nummers an letters. A study that leukit at whit gars ilk pairt fand that the extra time on pairt B maistly reflects task-switchin, while pairt A reflects sicht-search an motor speed 1. That is why the difference atween the twa pairts (B minus A) is aften leukit at on its ain.

• Pairt A: 20 circles nummered fae 1 upwards. Tap them in order as fast as ye can.
• Pairt B: nummers an letters. Switch atween them in order: 1, A, 2, B, 3, C an sae on, up tae 10 an J.
• A short untimed sample comes afore ilk pairt (ye can skip them). The clock for ilk pairt sterts whan its circles appear. A wrang tap flashes reid an is coontit; cairry on fae the last richt circle.
• Ilk rin haes a new layout. On a phone the board is turned on its side sae it fills the screen. Leavin the page ends the rin, acause the test is timed.

• Pairt A an pairt B times: lawer is faster.
• B minus A: hou muckle langer pairt B tuik. This taks awa maist o yer tappin speed an leaves the cost o switchin.

The oreeginal test is dune wi a pencil on paper, an the published reference values come fae that version. Tappin on a screen chynges the muivin pairt o the task, an screen size chynges hou far ye muive, sae thir times cannae be compared wi paper results or uised tae judge onything aboot health. We shaw nae norms. Compare wi yer ain rins on the same device. For anither test o switchin aff a habit, gie the Stroop test a try.
