Chimp Test

For 2007, researchers for Kyoto University train chimpanzees to touch numbers for screen in order. For one version, as soon as di chimp touch di first number, all di oda ones turn to plain white squares, so e gatz do di rest from memory 1. For one harder version, dem show five numbers for just small time before dem turn blank. One young chimpanzee wey dem call Ayumu get most of dem correct, and none of di humans wey dem test come near am 1 2.

Di story get another side. Another team point out say Ayumu don practice plenty, but di humans never practice. When two people practice di same task, dem get accuracy wey match im own 2. So di task show how much practice matter, just as anything wey concern chimps.

E dey measure short-term memory for where things dey and di order wey dem follow: you take in where several numbers dey at once, then remember dem without seeing dem. Unlike di study, no time limit dey before your first tap, and di number of squares go keep increasing as long as you dey get rounds correct.

• Di first round get 4 numbers. Look for as long as you like, then tap 1.
• Di oda numbers go turn blank squares. Tap dem in order: 2, 3, 4 and so on.
• If you finish one round without mistake, dem go add one number. Wrong tap go use one try, and di round go start again with new positions. 3 wrong taps go end di test.
• Your score na di most numbers wey you get correct for one round.

Because practice make big difference for di research 2, expect say your score go rise for your first few times. Na mostly because you dey learn di task. Once e stop to rise, your attempts go tell more about your memory that day. For test of sequence wey you dey see one step at a time, try di sequence memory test.
