The task

In this task, your client must locate a symbol in a grid full of intricate symbols and letters (intruder) that differs from other symbols (all of which are identical), and catch the intruding character that was shown before starting the task and that does not belong.


What It Trains

Primarily, this task exercises your client’s sustained attention and concentration skills. Attention is the essence of focus. Your client will need to focus on looking for a specific target and ignore other visual information that could distract them. Any time a person pays attention to something, visual information is stored in the brain. This visual information has value, but only if it is gathered, measured, and analyzed for a specific use case. In addition, this exercise requires your client to practice their visual scanning and shape recognition skills.


You can modify the type of help (with help, with intruder, multi-symbols, or odd one out, or not), the size of the grid (2×2, 4×4, 4×6, 4×8, 6×8, 8×8, 8×10, 8×12, 8×14, or 8×16), the number of sequenced series (2, 4, 5, or 10), the types of character (letters and numbers or symbols), and the response time (unlimited, 120, 60, 30, 20, or 10 seconds).
