Executive Functions





The task

There are two tasks to this exercise. In the first part, a series of 4 to 16 letters or words must be linked in alphabetical order. The second part demands to alternately sort two series of items.


What It Trains

Like the Trail Making Task Part A & B, this exercise requires your client to be able to switch between two kinds of stimuli to create a path connecting both sets of stimuli as fast and as smoothly as they can. Using either numbers and letters, words and numbers, or words pertaining to two different categories, your client must effectively connect a number to a corresponding letter or word, or correctly connect words of two different categories to one another. Your client’s dorsolateral prefrontal cortex (DLPFC) is challenged in this exercise as the DLPFC is the “hotspot” for cognitive flexibility.


You can modify the type of the task (letters and numbers, words and easy numbers, words and difficult numbers, words related to 2 different topics), the number of elements to sort (from 4 to 16), the way previously sorted elements are handled (hidden or not), the behavior after a mistake (start over or continue) and the time limit (from 30 seconds to unlimited).
