This task requires adults to judge sequences of three numbers and determine if they are in order (ascending or descending).

In the task, for the non-counting sequences, there are 4 ascending, 5 descending, and 8 unordered (4 that have the first to digits ascending and 4 with the first 2 digits descending)

For the counting sequences, there are 3 ascending and 4 descending and 8 unordered (4 that have the first two digits ascending, and 4 with the first 2 digits descending).

Orders are switched in Form B.

This measure was developed by Heather Douglas as part of her M.Cog.Sc. thesis at Carleton University.
