Test for Connecting Points

Di trail making task na one of di tasks wey psychology researchers dey use pass. For Part A, you follow numbers for order; na mostly finding things with your eyes and how quick you fit move. Part B add switching between two sequences, numbers and letters. One study wey check wetin dey drive each part find say di extra time for part B mostly show task switching, while part A show visual search and motor speed 1. Na why dem dey often look di difference between di two parts (B minus A) by itself.

• Part A: 20 circles wey get numbers from 1 go up. Tap dem for order as quick as you fit.
• Part B: numbers and letters. Change between dem for order: 1, A, 2, B, 3, C and so on, reach 10 and J.
• Small sample wey no get time limit dey come before each part (you fit skip am). Di clock for each part start when di circles show. Wrong tap go flash red and dem go count am; continue from di last correct circle.
• Each time you run am, di layout go change. For phone, dem go turn di board sideways so e go fill di screen. If you comot from di page, di run go end, because dem dey time di test.

• Part A and Part B times: lower time mean say you faster.
• B minus A: how much more time Part B take. Dis remove most of your tapping speed and leave di cost of switching.

Dem dey do di original test with pencil and paper, and di published reference values come from dat version. Tapping for screen change di movement part of di task, and screen size change how far you move, so you no fit compare dese times with paper results or use dem to judge anything about health. We no show norms. Compare your runs on di same device. To try another test wey check switching off one habit, try di Stroop test.
