## question about selecting a stimulus from a set and presenting it once...

 Author Message vz29 Distinguished Member Group: Awaiting Activation Posts: 69, Visits: 183 Hi,I'm running a priming study and wanting to present a letter string as a prime. I'd like to have Inquisit select one letter string from a set and then present this letter string throughout the entire experiment.In the past I've done this in a very inefficient way -- by specifying a for each letter string. e.g. / numitems = 18/ items = baseline1/ select = noreplace/ 1 = "RRR"/ 2 = "RRR"/ 3 = "RRR"/ 4 = "RRR"/ 5 = "RRR"/ 6 = "RRR"/ 7 = "RRR"/ 8 = "RRR"/ 9 = "RRR"/ 10 = "RRR"/ 11 = "RRR"/ 12 = "RRR"/ 13 = "RRR"/ 14 = "RRR"/ 15 = "RRR"/ 16 = "RRR"/ 17 = "RRR"/ 18 = "RRR" / numitems = 18/ items = baseline2/ select = noreplace/ 1 = "GGG"/ 2 = "GGG"/ 3 = "GGG"/ 4 = "GGG"/ 5 = "GGG"/ 6 = "GGG"/ 7 = "GGG"/ 8 = "GGG"/ 9 = "GGG"/ 10 = "GGG"/ 11 = "GGG"/ 12 = "GGG"/ 13 = "GGG"/ 14 = "GGG"/ 15 = "GGG"/ 16 = "GGG"/ 17 = "GGG"/ 18 = "GGG" / numitems = 18/ items = baseline3/ select = noreplace/ 1 = "MMM"/ 2 = "MMM"/ 3 = "MMM"/ 4 = "MMM"/ 5 = "MMM"/ 6 = "MMM"/ 7 = "MMM"/ 8 = "MMM"/ 9 = "MMM"/ 10 = "MMM"/ 11 = "MMM"/ 12 = "MMM"/ 13 = "MMM"/ 14 = "MMM"/ 15 = "MMM"/ 16 = "MMM"/ 17 = "MMM"/ 18 = "MMM" / numitems = 18/ items = baseline4/ select = noreplace/ 1 = "BBB"/ 2 = "BBB"/ 3 = "BBB"/ 4 = "BBB"/ 5 = "BBB"/ 6 = "BBB"/ 7 = "BBB"/ 8 = "BBB"/ 9 = "BBB"/ 10 = "BBB"/ 11 = "BBB"/ 12 = "BBB"/ 13 = "BBB"/ 14 = "BBB"/ 15 = "BBB"/ 16 = "BBB"/ 17 = "BBB"/ 18 = "BBB"How can I do it so that Inquisit chooses from a set that contains the four letter strings from above?
