CognitionKit Digit Symbol Substitution (DSST)
The CognitionKit DSST is a global measure of cognitive ability, requiring multiple cognitive domains to complete effectively.
The task presents participants with an array of abstract symbols associated with numbers. When a particular number is highlighted on screen, the participant must draw the corresponding abstract shape using their index finger on the smartphone. This is a timed test, so the participant must try to complete as many symbol-to-number matches within the allotted timeframe.
Outcome measures include total correct, errors and latency (movement latency and response latency).
We would recommend using this test to assess cognitive function in:
