Abstract
It is possible to create pairs of Latin squares that are digram balanc ed (in other words, that counterbalance immediate sequential effects) in a Greco-Latin design. A behavioral researcher can use these squares to design an efficient, well-balanced study without relying on chance . Researchers can apply these squares to any experiment in which they must pair conditions with different stimuli in a within-subject design . For experiments with a large number of conditions, however, the proc edure is very time-consuming if done manually. A BASIC program is desc ribed that generates the correct pairs of squares for experiments with as many as 80 conditions.
