    How do I program a game with a Payoff structure (case 16545)

    Hi all,

    I'm trying to program a game with 200+ trials where participants pick between option A and option B on each trial. Each option has a specified payoff structure that depends on what they picked in the last 5 turns. I can articulate the payoffs with one equation. The payoff for picking A is n where n equals the number of times the participant picked A in the last five trials. The payoff for picking B is n+3 where n is still the number of times participants picked A in the last five trials. After each trial I want to display the number of points they earned on that trial as well as their cumulative points up to that trial.

    Can anyone tell me if there is a way to do this in direct RT? If so, can anyone help me?

    Thanks!

    DirectRT does not currently have the capability to do or use calculations while running an input file. However, something like you describe could be possible in MediaLab using the responses.xls feature. Take a look at the Advanced Features section of the MediaLab manual here for more information: http://www.empirisoft.com/medialab/h...d_features.htm.
