PRLG (PseudoRandom List Generator) is an application to generate pseudorandom lists from a stimulus file. Constraints can be set to limit the number of similar successive items (n-back: 1, 2, etc) based on the levels provided in the columns. The program also provides information about the randomness of the generated lists. This includes 1st and 2nd-order transition information. The transition information (Same or Different responses across n-back trials) can be used as a constraint as well.

PRLG runs on macOS and Windows computers.
