Digit Symbol Substitution Task

Digit Symbol Substitution Task measures processing speed. The task begins with a brief animated tutorial in which participants are instructed to match 5 different symbols with corresponding numbers. Once the 60-second session starts, participants are shown a symbol and then must identify and click the corresponding number as quickly as possible. After each selection, a new symbol appears. The digit symbol pairs remain the same throughout the session but change in future sessions.
