This task requires participants to respond continuously to a series of stimuli such as numbers according to a set rule. For example, they might press a button for all numbers except "3," and refrain from pressing it when "3" appears.
It measures "sustained attention" and "response inhibition" (the ability to suppress impulsive responses), assessing how well someone maintains focus and their tendency toward errors or impulsivity.

This task measures the ability to suppress interference in information processing by requiring correct responses in situations where word meaning and text color conflict. For example, if the word "Red" is written in blue ink, you must say "blue."
By suppressing automatic reading and correctly naming the color, it evaluates "selective attention," "interference control," and "executive function."

This task involves judging whether the current stimulus matches the one presented "n" steps earlier in the sequence. For example, in 2-back, you must remember and compare with the stimulus from two items back.
It primarily measures "working memory," as well as "attentional control" and "cognitive flexibility." Increasing the n-level makes it possible to evaluate memory capacity and manipulation limits.

In Part A, participants connect numbers in order (1→2→3), assessing "processing speed" and "visual search ability."
In Part B, they alternate between numbers and letters (1→A→2→B), measuring "cognitive flexibility," "set-shifting," and "executive function."
The number of errors and completion time can be analyzed to detect issues in executive functioning.
