Millisecond Forums

Hi forum users,

I hope you can help me programming the following study: I want to program the classic Wason rule discovery test to assess confirmation bias (Wason, 1960; for an example, see http://www.nytimes.com/interactive/2015/07/03/upshot/a-quick-puzzle-to-test-your-problem-solving.html). I’m not sure how to do this and whether it is even possible in Inquisit. All the help is appreciated!

In the original study participants were presented with a series of three numbers (viz., 2,4,6) and told that the series of numbers confirm to a certain rule. Participants were instructed to discover this rule by writing down sets of three numbers.
After writing down each set, participants were informed whether the series of numbers that was written down confirmed the rule or not. By testing their hypotheses this way, participants could infer the rule behind the series of numbers.

Because the rule is quite simple (three numbers in increasing order of magnitude) I think/hope programming this in inquisit is not very complicated, but I do not know which option/function to use.
Again, all the help is appreciated.

Best, Koen
