Hello Dave, I am trying to create judgment of contingency task using the Inquisit 4. I want to be able to create a visual feed where there is a light bulb in the middle of the screen and a push-button towards the end of the screen (lower end). What I want to be able to do is to vary the probability of 1) light coming on after a participant presses a button within the allotted 3 or 5 second where they are asked to push the button and 2) light coming on after a participant doe not press a button within the allotted time. And I also wan to be able to vary the number of trials people would get. Is this something that can be achieved using the Inquisit? I am trying to gather scripts that would help me build this kind of experiment. I would really appreciate it if you could help me with the script or point me to direction where I can find scripts people have used/created to do this kind of experiment. Thank you so much for your self in advance, Please let me know about this and happy new year!
